So i have played around with flashing different ROMs to my Nitro and quite like where CM10 is going. The only real issue that i have found is that while on CM10, my phone doesn't seem to be using 4G(which I understand is HSPA+). On the ICS Stock ROM, I can go to Settings > About Phone > Status(or something like that) and it says "HSPA+" and never changes. Wondering if it is just CM10, I flashed CM9 and had the same issue.
Today, I found that if i am connected to WiFi, I can disable it and my phone will show "HSPA+" for about 4 seconds, then go to "UMTS" for a second, and then to "HSPA". It never returns to "HSPA+".
This seems like a pretty big issue but every time I post a question about it in the various threads about CM, it gets skipped over and nobody talks about it. So, I thought it was time to make a thread for it.
Mine seems to work well on cm9 and cm10 not sure why your having an issue

Try to reflash your baseband and firmware. That should do the trick.
Good Luck:laugh:

Nevermind, just saw on a different post that you're trying to flash 20c correct? Even though it may be compatible, I would try to stick with what is stable with CM10. One of the band versions is of course the 10j baseband dated 26 Feb 2012. With all the security measures from lg, at&t, and Google combined, it is possible that they may have some sort of block installed that slows you, unless you run their genuine 4.1 stock jb software. It would not suprise me at all.

I found out that it is actually a feature inherent in the radio that it only uses 4G when it needs it in order to save on battery.
I'm having a similar problem: every time the phone reboots (and it unfortunately does this frequently since going to CM9), the phone won't see LTE. I have to go into the Field Test mode (*#*#4636#*#*), where it is always reverted to WCDMA preferred and switch to LTE/GSM auto.
Any ideas?

I had this. I fooled around getting Field Test to show LTE/GSM auto, then going into the usual menu, putting it to LTE/GSM auto, going back to Field Test and checking it was Ok, then going back to the menu, switching to GSM auto, then going back to Field Test, etc., then going back to menu, switching to LTE/GSM, then checking Field Test, then rebooting (or something like that
BTW, there's an app in the market called "Hidden Menu" that will save you typing the key sequence each time. (There are actually multiple apps with the same name - the one I use has green #'s in the icon.)
Good luck!
Nothing Above EDGE
Hello,
I'm a new member, but I have been an XDADev reader and android/iPhone/PC/Mac/Things that go buzz, whirr, click, zoom and or boom/ for my whole life.
I have a Nitro HD, (AT&T P930).
I followed Mattman's (Thanks! WELL done.) improved guide on unbricking/rooting etc. I have been rooted and updating every week or so to the latest CM10 nightly (VERY buggy at first! But half the "fun" for a nerd like me).
The dam shame of it is that I cannot get ANYTHING above EDGE (2G) to work. I have been stuck at 100kbps or so for weeks now. My only saving grace is that I have wifi at work and at home. But anytime other than that I am basically without any significant data.
When I initially saw this thread, I thought YES! Finally somebody has reported this and we are going to get to the bottom of it. But now after reading through it, (Especially Mattman saying its inherent to the radio) then perhaps MY problem is an isolated one and I did something wrong? I was wondering if anyone would like to help me address it? Because my problem is that while on CM10 it truly does NOT connect to 3G or 4G, ever. (went back to stock ICS and got minimum 3G all day, with spurts of 4G wherever my phone found it).
I am pretty good at this crap, so I wont need much hand holding. Just point and shoot me in the right direction
What I'm thinking right now is that perhaps my baseband is not correct, or maybe I should re-flash it?
Current basic info:
Network: T-Mobile
Mobile network type EDGE:2 (Poop)
Service state: In service
Mobile network state: Disconnected (wtf? I can get texts/calls/slow as shyt data)
Android Version: 4.1.1
Baseband Version: P930-MDM9200B-V10f-OCT-31-2011-XX (should it be this?)
Kernel version:
3.0.8-cynaogenmod+

Thanks alot to anyone who can assist. (I'm close to giving up and going back to stock ICS "permanently", 3G and 4G work with that BTW).

It's because you're on T-Mobile. AT&T phones won't work with T-Mobile's 3G/4G data.
I should clarify that you can roam onto AT&T's 3G network (because of the deal between AT&T and T-Mobile when their attempted merger failed), but that will only allow you to use a small amount of data (i.e., a small fraction of your full data plan allotment). Details here: http://support.t-mobile.com/docs/DOC-3299
I'm not sure if you need to do something special to get data roaming to work for you, but it's only going to give you 200MB of data use per month at the most, so it's probably not the solution you're looking for.

Thanks very much for the info Drumist, Tmobile says the opposite, but I will call them and try to talk to someone in their higher level tech support (surprisingly good, some of them are!) and see if they have a different story to tell.
Further Clarification: The phone is unlocked and I am a T-Mobile subscriber with a 2gig per month 4G plan and a Tmobile sim card is in the phone.
The phone runs fine all the way up to the 2gig limit at 4G speeds on the stock ICS rom. (And I have had other unlocked ATT 4G phones run at 4G on tmobile's network. This is the experience that leads me to believe the problem is with the current rom).
I'm really getting the feeling I should just go back to it (rooted v20c ICS). The amount of variables here are a bit more than my time resources permit to ferret out.

Well, it's possible that it works. The Nitro HD supposedly supports the 2100MHz 3G band (which I didn't realize until just now looking), although AT&T doesn't use that particular frequency. T-Mobile uses both 1700MHz (AWS) and 2100MHz for their 3G/"4G" services. As I understand it, most of their network uses 1700MHz, with a smaller portion using 2100MHz. You may be lucky and happen to reside in an area with 2100MHz service, or I'm just wrong about that and 2100MHz is common. In any case, if you say you get service on stock ROM, then you get service.
So, based on that, I'd say the most likely cause of your problem is that you don't have the proper APN settings for T-Mobile on your device. You can find those settings here: http://support.t-mobile.com/docs/DOC-1979

Following rani9990's advice earlier in this post, I did go through the APN settings based exactly off of that specific page. And even tried the mytouch4G APN settings, both worked, but both still only resulted in an EDGE connection. And I tried it again, in exasperation, to no avail.
Thanks again drumist, your time and advice is truly appreciated and valued.

Hello everyone, this is my first thread so please be gentle!
I currently have a G1, and hope to put it to rest very soon, and get the new G2!
(staying true to the "G")
I use an AT&T sim card on my current G1.
I have been lurking (for quite some time now) on these forums trying to find an answer to using the AT&T Sim Card on the G2. I have yet to find my answer through searching.
The capabilities I'm looking for to use on a G2 with an AT&T sim card include:
at least 3G network data speeds
normal use of calling
(I live in the US, and I don't know if that allows me to have 3G instead of EDGE)
Some things I have found:
In one other forum it said the AT&T would work on the G2, however it would only work on the EDGE network. (which I believe is 2G? please clarify if you can)
"
TMO's 3G network runs on the 1700Mhz spectrum.
AT&T's 3G network runs on the 850 and 1900Mhz spectrum.
The G2 is incapable of operating on AT&T's 3G network but will work just fine on the EDGE network.
"
the "[Guide] Subsidy Unlock, SuperCID, and Radio S-OFF" presents a sim unlock, so would that mean I could use the 3G data networks on AT&T? and have local calling? or is that something else?
Thanks in advance!
The Subsidy Unlock would allow the use of the AT&T sim card. I'm quite sure you wouldn't get the 3G+ speeds. Edge only, just like the G1.

That was from someone in the sim unlock thread. Not sure if any network chosen means 2g/3g but I would think 3g would be supported.

It isn't just your phone, I don't think any phones ever come out with the correct bands for ATT and Tmobile...Even the N1 which is supposed to be a world phone was only EDGE on ATT
The T-Mobile G2 will not work with 3G on AT&T (as you stated in the original post, the 3G or UMTS bands are different). It will instead use the regular GSM bands for 2G data.
If you want a Desire Z that works on AT&T's 3G, you have to get the NAM version offered by Bell Canada (check out the Desire Z forums). Once unlocked, it'll work fine on AT&T's 3G network.

Actually, Nokia's latest smartphones are pentaband - they can use 3G on AT&T, T-Mobile, and the European networks. This includes the C7, N8, and upcoming E7.
I have the N8 right now and have used it on both AT&T and T-Mobile with 3G.

How do you get the $10/mo data plan? I don't have that option!
Yeah I know this is going a little off topic (sorry mods)
but I think he's talking about individual unlimited data plan for "basic" phones?
I kept trying to pester AT&T about it.
So is it true you don't need the DataPro plan in order to acheive 3G data networks with smartphones?
And you can use the "basic" unlimited data plan for cheaper for the same 3G networks?
The AT&T reps kept saying otherwise.

I have a family plan with an Iphone line (sister). My phone (originally a BB when contract signed) and 2 Dumbphones (parents)
What I did was, take my SIM card, and put it into one of the dumbphones. Went into ATT and had them add unlimited Data to that line at the $10 option. (And cancel the BB services since I wasn't using the phone anymore - told them I sold it on CL) Went home and returned the SIM into my BB and I was all set to go with unlimited Data. The only thing that didn't work with the BB was the push Email services...
If you go to your online account with ATT it will show you an image of the device you are using with service and although it showed my device as a BB at the time, (after returning the SIM to the BB) the $10 plan continued to work without any hitches.
Now that I have a phone that is unbranded with an IMEI # that ATT doesn't recognize, they don't have an image for my phone, so they have no way to detect that I am using a smartphone.
I have used the $10 plan with many devices: BB, Touch Pro, Nokia E71, etc and have never had any problems.

Yes that is the plan that I am referring to and yes the reps are full of crap. ATT wants to charge you more for having a 'smartphone' even though you use the exact same data, frequencies, and service as other users. There are many ways around this, but going into an AT&T store and trying to 'reason' with them is not one. I suggest the method I used with a dumbphone. Alternatively, you can do the same process online through account manager without having to deal with a live person.
Side question here. I'm thinking about giving the G2 to a friend on AT&T. The thing is that he doesn't want to pay for a data plan. Will AT&T force a data plan onto the line? Also un checking data enabled, will that stop all data over the cellular network so he doesnt get charged at all?

I don't think they can force a data plan as the phone is not being subsidized by ATT because of a contract.
In theory disabling data will stop all data but in reality he will probably still use a bit of it. Search the forums as I remember another user having the issue of zero data use.

I finally did the whole unlock, super CID thing using gfree and adb.
Just want to make that no one has found a way to get 3G speeds on the G2?
Or is EDGE my only choice? I understand the whole band thing as well.
No. From what I've gathered on the g2 being on at&t, its impossible as the radio hardware is different and will not pick up the 3g bands. Flashing a different radio to match up the bands won't work, either (it will possibly brick your phone, actually.)
Go with the NAM Desire Z from bell canada. Its your best bet.

I don't think I've had over two bars since flashed over and I get excited about those. I think I read in another thread (but could be wrong have been googling) and I think it's because we are a port and still have some ics features..? Don't quote me on that tho.

Any help with this would be highly appreciated. Just bought a gnex from someone and I only really get a signal at home. I have pretty much no service anywhere that I used to have service with my Amaze with no problems before. I was hoping changing to jb might help but nothing.

Did you try to prl before you flashed over and was everything updated first?
*Android is upgrading...*
No, something happened to me too when I tried JB (VZW GNex)
I'm in the same boat (VZW GNex).
My stock 4.0.2 reception was "OK", not great. Same with stock 4.0.4 OTA update. Same after rooting. Same after CM9.
Then I tried jdkoreclipse 2.1 JB, and added the "Wi-Fi fix". Everything fine for a couple of days, then reception SUCKED -- empty triangle instead of bars. Toggling between "CDMA + LTE", "LTE only", and "CDMA only" made no difference.
I Reverted back to my prior CM9 image -- still bad, but I could get a signal outdoors sometimes, in a stronger area (sometimes it would help to turn Wi-Fi off). I re-flashed the proper radios -- no material difference.
I can't get any VZW signal at all inside my house or in the yard, inside my office or outdoors in front of it, inside or outside a Target store (all in an urban area -- some other outdoor areas I could get a stronger signal).
Last night I tried Razor's JB 2.6 -- same problem. Everything's working great on JB, (with the exception that my phone is not actually usable as a phone in many areas of the city). People complain that they have to leave messages that I have to retrieve from Google Voice over Wi-Fi, then I return the call on a land line. I tried "re-seating" my SIM card too.
It definitely appears to me as if something happened a couple of days after I first tried JB, that tanked my VZW reception, even after I reverted back to a prior saved ICS image, and re-flashing the 4.0.4 radios in ICS did not help. Every so often, I'll get a good signal outdoors, but I can't count on it.
I had better reception on ics also. I wonder if there will be a radio update when they finally do the full release
*Android is upgrading...*
One other thing that may be diagnostic
I don't know if this might make a difference, but somewhere along the way, Titanium Backup Pro reported that it detected a change in my Android device ID, and offered to revert it. At first I didn't revert it, but as I had more problems, I went ahead and reverted it as recommended. That was some time ago, and it did not happen again. Since the first JB versions originally came off of a Google I/O nandroid, is it possible that the one I loaded retained the Android device number from the source device, and maybe that played a role? Like I said, I reverted the ID AND later reverted to a prior saved ROM.
@ Jedininjafication, I noticed that you asked jacktrck if he "tried to prl before . . . ." I did a lot of things before I flashed, but I have to admit that I don't know what "prl" stands for. Maybe I did it, but I don't know. I can't think of anything that "prl" would stand for.

Just so we're clear, this goes way beyond merely being "inferior" to ICS. We're talking NO SERVICE in a significant part of my city, whereas I used to have service to varying degrees of strength before.

PRL is Preferred Roaming List. It's essentially a list of towers that your phone can use. Keeping it updated avoids your phone looking for towers that don't exist (in the case of a tower being removed) and allows it to "see" any new towers that have been constructed.
On Verizon (and Sprint?), the PRL is automatically updated via the SIM for 4G devices and manually via *228 on 3G devices. On AT&T (unless something has changed in the last few years), it's updated via a star coded call only, though I don't know if AT&T also uses *228 or not.

Ah, that's slightly different than VZW. For us, we can do *228 and select option 2, or we can dial *22899 (I think that's the one) directly. In the case of the Nexus, it's a moot point (on VZW, at least), since we're updated manually via SIM. Most times attempting to dial *228 will result in the phone refusing to dial.

He could try having them push an update. Sprint has had me do the *#*#4636.... Code and change my network to cdma(prl) then go do the *228.. And that's worked. I had garbage service other day until I did a ping in same dialer code. I don't know if menu is the same on Verizon tho
OH! don't do the SCRTN if your do call them! I did that and since am not stock it completely set my meid and stuff to all zeros and they couldn't figure out how to fix so i had to restore

I was having terrible data drops and couldn't find a solution. Turned out to be a faulty radio. Got a replacement and haven't had any issues since. So it does happen I guess.

So, what do you guys think of the Android ID thing? Non-issue? And what would have caused it to change in the first place?

after i did the scrtn thing and everything set to 0000000000 and restored back to a previous version and did the update I haven't really had issues. I do at my house in my room but have been good other than that. I don't even know if Verizon has that menu, but it's the factory data reset code for us. Doesn't reset the other stuff.

i have no idea what happened but this is on 3g. Not wifi. no lte here..I'm second round. Awesome
Android is upgrading...
I was having great 4G signal running any ICS rom, however my signal would drop 4-5 times per hour. I called verizon to see what they could do, as I had read that some people had better luck with a replacement phone or sim card. Verizon first sent me a replacement sim card which made it worse. Next they sent me a replacement phone. The first replacement, which I have no clue how it passed re-certification, because you could see the 3-pin charging area from the front of the phone. The housing was not seated correctly on the phone after they refurbished the phone. So I called verizon back again and I got a second replacement. This one was free of any visual defects that I could see and runs fine on ICS or JB roms.. However I am still getting awful signal where I used to get 3-4 bars 4G all constantly on my original nexus.
If I reboot the phone it locks on the tower at 4G for maybe 1-2 minutes, then drops to 3G full bars, then slowly over the next few minutes drops to 0-1 3G bar(s) and then down to 1X.
I suppose my next move is to get yet another replacement and see if I have any better luck. This is becoming a nightmare.
I don't know if this is a question or more of a poll...
I think I'm getting horrible 3G speeds here in Austin, TX. It also seems like I'm being capped. When I have full bars, speedtest always shows around a 3Mbps down and 1 Mbps up transfer speeds. I've tested this in many places around North Austin / Round Rock.
What speeds are others getting?
Could my sim card or data plan need tweaking from AT&T? I ask this because I was previously on a Galaxy Note with LTE and they had to switch me to a LTE plan at the time. Outside where I work, the LTE signal strength is very strong and I've gotten amazing speeds with the Note. But with the Nexus, I get the 3/1 speeds.
Any ideas?

Thank you for helping me.
I'm on a smartphone plan. Which APN settings are you wanting? There are a lot!
I live in Bastrop, like 30 miles east of Austin, and am getting about 2.5-3 down and .4-1.2 up. I was pretty disappointed because I thought I had remembered pulling more on my Captivate(smart phone plan though), too bad it broke. I'm using the MediaNet plan on ATT with AndroidHD Revolution(4.1.1) and Franco r223.

If you're on the smartphone plan, I'm assuming you're using the "phone" apn? Also, you're aware that you can get unlimited hspa with the non smartphone plan formerly known as media net.
Who knows this could be purely speculation but let's say AT&T already has your imei number you could be automatically bumped to the same smartphone data plan if you attempt to use the dumb phone plan.
I am unsure how quick AT&T is figuring this stuff out. I had an AT&T GS2 and switched to a dumb flip phone then bought a GNex, took the sim card out of the dumb one and transplanted into the GNex and boom, unlimited data and texting for $30 a month.
I'm already on an unlimited smartphone plan. I chatted with AT&T support and there are currently no restrictions on my data plan. He also switch IMEI from the Note to the Nexus and moved me from a LTE plan to 3G plan. Data speeds remain the same.
I wonder if anyone with a GSM Nexus in Austin is able to get > 3Mbps...
Try the phone apn?

You are on a SGS2 with HSPA+? Which city are you in?
Try testing with actual downloads instead of speed test sites. My speed test (I'm in northern Colorado) always tells me about 3Mb/s down 1Mb/s up too, but on actual downloads and manual tests, I hit 8-10 Mb/s even in kind of rural areas.
I'm in Indiana and get around 3-4mbit down and 1-1.5mbit up. The fastest ive seen once is 7mbit down.

I remember with the captivate, the speeds would vary widely depending on which part of town I was in. But with the Nexus, it just seems very artificial to hit right around 3 down / 1 up every time. Almost like AT&T is capping it similar to what they did to the captivate. The modem AT&T put on the captivate was throttled for whatever reason but flashing an international modem removed it.

Yeah. I had to send my Gnex in for service. Only got to use it for 17 days
Harbor Springs Michigan
Sorry to bring back an old thread, but I am wondering on this myself. I bought my gnex from google play, got it and noticed that the data rates are pretty steady at around 2.5 - 3.5 max down, and .9 - 1.2 up. The gnex has a 21Mbit HSPA+ radio in it, so in theory it should accept whatever AT&T can push to it. However, I came from an Atrix 2, and can vouch for the fact that the Atrix 2 when using the PTA APN on HSPA+ (no LTE for about 200 miles where I'm at) will download consistently between 7 - 9 Mbit... Same server on speediest.net, same APN, same place, the signal is within 1dBm of each other.
Because I have found no base band that can change this, nor any APN setting I am starting to believe that if AT&T gets an IMEI of a phone that it doesnt recognize, they will throttle it.
Any one else have any insight? 3.5Mbit is plenty, but I'd like to get the same speeds as what I consider a lesser device.
If I could find a way to change the IMEI I'd test this theory.
^^^ Suprisingly, Its not att at all. Ask anyone on these forums, samsung has notoriously bad radios. Signal and cell strength just are not that great. And you can you can especially feel the difference coming from a motorola device. They have the strongest radios of all the major oems by far. No one even comes close.

Thanks for this update. just saw it. It's frustrating knowing our phones could do so much better.
So earlier there was confusion whether the T999 had the processor for LTE or was gimped. We've seen conflicting reports from T-Mobile, who claimed it is gimped and doesn't have LTE, but at Target Mobile, the T-Mobile GS3 is advertised as "4G LTE coming soon," and some think the LTE radio is simply disabled. I did the stat check app, and it did list the MSM8960. Has anyone found out the truth yet? CS from T-Mobile told me on the phone its getting LTE via OTA next year.
I believe this screenshot answers your question.

The T999 does NOT have an LTE radio, or at least it is disabled in microcode (hint: we ain't changing it). Qualcomm can and does have different versions of the S4 family of SOCs identified as an MSM8960. It is more accurate to refer to the SOC as an S4 Plus, which has many different variations, the main differences being modem configurations. The T999 actually has the MSM8260A (using the older terminology), which is basically the MSM8960 without the LTE modem. This can be verified by looking at some getprop parameters. Most software is just going to show you MSM8960, which is the board name/type, etc.

No. Just because it is in a software menu does not mean it is supported in hardware. Try to use it on AT&T LTE, then come back and let us know how that worked out.

What do you mean "disabled in microcode?" If it is that, could an OTA fix it? I've heard about MSM8960 vs MSM8260a but not only have several T-Mobile reps told me over the phone that that phone will get LTE, but one of their live national sales reps told me it will to my face, and I work at a retailer which sells T-Mobile alongside AT&T and Verizon.

I had a Samsung rep at a T-Mobile store (the day I bought the phone) tell me it is LTE capable when T-Mobile flips the switch. So basically take that how you want to. I'm taking it with a grain of salt, but hope that it is true . Would be nice to be one of the first people to actually use T-Mobile's new LTE Advanced Network. Its going to fly!

not to mention the current version of LTE, 3GPP release 8, isn't technically 4G either, so this is awesome if its true. LTE Advanced is supposed to be the first "true" 4G." These conflicting reports are starting to bother me. But either way, even HSPA+ is far, far better than any regular 3G, especially CDMA 3G, which is snail slow.
the jelly been leak has LTE enabled in it so i think its coming with JB. shows it right in choose network mode.
Look up microcode on Google or read the Wikipedia article. That would be a good start. It is how processors are programmed, and no, an OTA will not change it. FYI, I don't know if that is specifically done with this SOC, I am just saying that features (seemingly hardware features to end users) can be changed with microcode. It may just not have the actual silicon. I don't know. Either way, from our perspective, it doesn't have an LTE radio.
The T-Mobile reps are wrong, at least for the phone that was just released. Simple as that. Now, there could be a hardware version update, or subsequent newer model released with the LTE radio. Certainly is possible, though it would likely have a slightly different model number, or be easily identifiable some other way.
I know you guys want the T999 to have an LTE radio. But, no matter how much you want it, that won't change the facts. The phone we have now doesn't have it. It's just one of those things that we will have to wait and see. Then we can come back and say, told you so. In fact, there is a JB update out now for the T999. Why doesn't someone flash that and try it out? Seriously, out of all the T999 phones sold, do you know ANYONE using LTE on it, whether on AT&T or elsewhere? If you do, please tell him/her to speak up. Think about it. Surely someone on these boards is an AT&T customer with a T999. It's not going to be "enabled" with an OTA...

The other person had a screenshot of this too. Just because it's there doesn't mean the hardware supports it. Why would it come with Jellybean when T-Mobile's LTE network won't even be out for months, maybe even a full year at the rate their refarming is going? And why would it even be ENABLED?
Also, everyone needs to STOP LISTENING to reps. Reps don't know anything more than most people who can use Google.

This has certainly been my experience, and is not limited to just T-Mobile. I had one rep tell me with a straight face that the OS on a Galaxy S Blaze 4G was not in fact Android, but rather a custom OS and skin designed by Samsung...lol Yeah...sort of... And there was the time that one swore up and down that GSM (2G old school GSM, not UMTS/HSPA) was superior to CDMA...for reasons he could not possibly explain except to say that...well it must be better since the rest of the world uses it.
Don't get me wrong, I know there are some bright and knowledgeable reps working for T-Mobile and others.

No. It just isn't going to happen, and their LTE Advanced network is a long time away.
If several people live and on the phone told you to jump off of a bridge, would you do it? Not to mention the fact that most of their phone reps are outsourced call centers that also know nothing.
not sure if it matters but a friend of mine used his upgrade to get the s3 on att. now I'm not sure what they claim or if there phone is different than out tmob version but i can say that i did hold his phone and ran a speed test while the icon in the status bar showed LTE, it maxed at about 36meg d/l. later that night at one of our other friends house the icon showed 4G so i ran speedtest again and it stayed between 11meg to about 18meg. reading one of the above comments about the att version just got me thinking about that so i figured id tell what ive seen hoping it would help in any way

No. Whatever it is inside the T999 is not LTE. So, no version of LTE will be compatible with it. I understand optimism, but wow... No joke, the T-Mobile Galaxy S3 does not have LTE. I wouldn't be so disappointed though since HSPA is no slouch and still has a bit of room to grow. I actually think the approach T-Mobile took with their network advancements makes a lot of sense. Not saying it is the best marketing strategy.
Seriously, there are people on this forum that have the T999 on AT&T. No LTE. Just find them, ask them, confirm. And no, it is not coming in an OTA. It will only come in a different version of the phone (quite possible). The phone you have in your hand now will not magically be updated to LTE. While UMTS/HSPA and LTE are actually not as different as most may think (same standards family, both decedents of GSM), they are still different and require specific hardware. There are technical differences.
FYI, the AT&T version of the phone IS different than the T999, that's why he gets LTE.

I haven't tried to root this handset yet. This is my #2 handset. The 1st the screen broke so I used my insurance to get another. I work with phones all day long including iPhones, other T-Mobile phones, AT&T and non-GSM phones such as Verizon for example. I deal with carriers such as T-Mobile, Simple Mobile, H20 and non-GSM carriers such as Boost Mobile. So i'm saying that I basically deal with it all. Now the problem i'm having is my own phone. I set to WCDMA only and i'm on the stock ROM of course. The phone will set itself from Band 4 to Band 2 from time to time however, when it sets to Band 2 there is no service until it swaps back to Band 4. I have troubleshooted and called T-Mobile and Samsung to talk to them to find out whats going on. Both of the handsets have done this #1 and #2. The service menu *#0011# shows that it is on Band 2 and it is receiving 2 to 3 bars of service but the availability is LIMITED. The About Phone -> Status menu shows that it is Out Of Service. And the carrier is unknown. The notifications area shows searching... or no service. The type of network is showing Unknown:0. This only happens on Band 2 WCDMA on my phone. On any other phone it works with no issue. I am wondering why my specific phone is not connecting to this band properly. T-Mobile has told me to contact Samsung. Samsung said they can't help me apparently. So what do you think the reason is why I can't connect? If you need screenshots I can take them.
I have a similar problem with my first note 2. My note 2 gets signals sometime and I cannot get 4g speed. I called up tmobile they where unable to fix the problem. So most likely somthing screw up on your phone and use your insurance to exchange a working one.

Its never worked properly on neither of the Note IIs i've had. So 2 devices with the same issue. I believe the issue is wide spread and there are many others with the refarmed band connecting issue. The phone should have come with the options of 1700 and 1900 WCDMA switching or both. Unknown:0 just means theres no option for it so it doesn't know what to show. However, I can't explain why its happening on the Note IIs only.
Another person, as well as myself, posted about this problem about a month ago. We both had the same exact issue... 4G works, 3G doesn't at all. Edge works, GPS works... 3G DOES NOT send/recieve any data. It has to be a T-Mobile issue and from the looks of it they are trying to ignore it. Honestly it becomes a huge issue when you're traveling and can't always access WIFI or 4G. It's something I would leave T-Mobile for... so they should consider tackling the problem and fix it.

This could be the same issue i'm having due to being in a limited 4G area its mostly 3G.
However, I can access 3G and 4G on phones that are not T-Mobile like AT&T Androids and iPhones and it works with no problem. I am wondering if this applies to the Galaxy S III and Note I also as I haven't tested that out yet. That's why I pointed it out at Samsung.
I wonder if it will be fixed when LTE Radio gets unlocked.
Developers should take notice that deal with the combo WCDMA 1700/1900 handsets to create a switch to go from WCDMA 1700 or 1900 and to use a combo of 1700 + 1900. So we could have the option to switch to a specific band rather than it jumping from 2 to 4 then back to 2 and 4 again.
Are you rooted?
Are you running a Custom ROM?
Have you flashed a Radio from anything other than a T-Mobile Radio?
Is it even safe to flash a radio other than T-Mobile?
Similar problem. Network data stopped sometime this afternoon. Tried sim in my sgs2 and worked fine.thinking of going to tmo store.

Not sure but the issue with band 2 might be LTE related and the nonworking scenarios are possibly just occuring as tmo expands their towers... not sure if im way off or not but I read that tmo is pushing some to 1900 to make room for LTE on their 1700... there for, again just a hunch, band 2 might be somewhat sporadic due to it being reconfiged to accommodate their LTE rollouts

I understand what your saying but its a weird occurrence to only not be working on the SGN-II. When I can hold another persons phone in the same spot with 1900 only and it ends up working. Only thing I can come up with is maybe blocking specific devices but I have no clue. Putting people on bands that don't work properly is something T-Mobile shouldn't be doing. If you for example are on that band and an emergency call comes through well you missed it till your back to the other 2 bands that work. I always root my devices however, i'm a lil scared to due to the fact that I might lose my EFS. Even tho I know I can backup my EFS. But then again I could lose it right after root. I don't understand why Samsung put vital info into a folder that could be removed.
Anyways sorry for the rant. I'm glad to know i'm not the only one with the problem.
The GNII is one of only like 3 phones that come with the LTE "on/off switch" so thats why Im speculating still, again I really have no clue but having read a few topics (like you wanted to know everthing about tmo efs/modem/imei/etc before modding anything) I feel like the LTE rollout and the band 2 issue going hand in hand

I think know whats going on. In your *#0011# Service Menu. When it switches to Band 2 the MCC-MNC change. It shows something like 310 260 when its on T-Mobile but 310 410 when its on AT&T. When on Band 2 for some reason it will swap from 260 on Band 4 to 410 on Band 2 therefore identifying it as an AT&T network. Why is it trying to connect to AT&T? I have no idea.

I think know whats going on. In your *#0011# Service Menu. When it switches to Band 2 the MCC-MNC change. It shows something like 310 260 when its on T-Mobile but 310 410 when its on AT&T.

I personally havent experienced any issues with my data/sms (then again if youre not receiving text/mms then how would one know they are experiencing problems in the first place?)
Because I havent had any issues I havent really tried to test my connection enough to know when im band 2 or band 4 or what exact mcc-mnc changes are occuring... for those worried about messing up their phones they need to just make sure they are always flashing a rom built foe their carriers' phone model and also make sure that each flash performed doesnt affect the modem.. (I know the modem part is hard due to roms being based off newer releases but as long as you are following my first suggestion (verify you are flashing the right carriers' phone model download) then there should never be an issue

T-Mobile's response is: The phone is designed to connect to the best network. Once Band 4 on T-Mobile has no signal while on 3G/4G WCDMA it will flop over automatically to Band 2 on AT&T. Due to the 7 year agreement we have with AT&T you should be able to access the network. However, we have lost a bunch of ROAMING AGREEMENTS recently. "Apparently AT&T DID NOT keep their promise of a nationwide agreement". Therefore your city might be on this list. This may be why you can't access AT&T. There is nothing we can do right now. Its a waiting game on when T-Mobile rolls out improved coverage onto 3G/4G 1700 WCDMA and 3G/4G 1900 WCDMA on its own. So in the future it is less likely that you will be put on AT&T. However, it is still possible. Sorry but we DO NOT have any CeI-Fi devices as I would offer you one as we are SOLD OUT. We don't expect any Cei-Fi devices to be in till this Summer.
So this device is supposed to go onto AT&T apparently and its not supposed to show as Roaming which is why Data Roaming Checked/Unchecked doesn't work.
Thank you! Finally a complete answer lol.
Is it possible to make it so band 2 only sticks with T-Mobile?

No and I found how to take screenshots. Wish I had pulled out my S-Pen out sooner.

When on T-Mobile WCDMA, about to lose signal as In Service, UMTS: Mode 3, Carrier as T-Mobile:
When on AT&T WCDMA, lost signal and flopped as Out Of Service, Unknown Network Mode 0, Carrier as Unknown:
Well they sold out of the Cel-Fi once they actually dropped the 2 YR requirement extension and then they got plagued with calls and SOLD OUT. I told her thats not good that means that the network is crap. She laughed and agreed. But look at the good AT&T signal makes me want to sometimes switch but everytime I think of leaving I couldn't.
According to the info I have gotten in my area GSM is approx. 485 meters away and WCDMA is 1,110 meters away in the opposite direction.
Figured out my problem. Phone got blacklisted.thanks eBay:thumbdown:

Now I can ROAM onto AT&T and have everything running except 4G is actually EDGE speed. I can even select AT&T as the main network.
LTE Band 2 1900MHz capability
I would like to know if an unlocked Tmobile note 2 has the capability to work on AT&T LTE Band 2 1900 MHz?
I know it works on AT&T GSM-1900 MHz frequency. it will even work on LTE band 17 700MHz frequency.
