[Q] Can you use this on AT&T network and vice versa when unlocked?

Hi,
I basically want to know if there is any difference between these devices, other than network provider lock.
Can you use the ROMs interchangeably?

I think the tmo model does support att's bands and u can probably interchange roms as well like on the tmo s2 and the skyrocket

We don't know for sure yet that the ROMs will be interchangeable. However, given that most T-Mobile phones support the 850/1900 NAM bands (GSM) needed for AT&T HSPA+, as long as the phone is unlocked it should work fine.

The Galaxy S2 did. Reading the specs page on the Tmobile website, I've come to the conclusion that the bands are identical to the AT&T variant's. I'm going to be doing the same thing.

Will hspa+ work? If so, tmo users who will be paying full price would be better off
Buying from att because its less than tmos full price cost.
Plus wireless tethering would work Because tmo doesn't have imei # of att phone.
Can anyone confim?

i would like to know this as well, paying 549 if a lot better than 639.

FYI only T-MO has HSPA +42 version of the S3 for those looking to buy from At&t.

anyone can confirm this?? does the gs3 from tmo works on att HSPA+ and vice versa and if the tmo gs3 works internationally on 3g networks.

All right,unlocked my T999 galaxy s3, put my AT&T micro sim in phone but I get no data. I can make phone calls no problem.Do I have to do anything with the APN settings?
Thank you!!

You need to make an AT&T APN. Also the AT&T version will not get 3G on T-Mobile without at the very least a modem flash.

O.K. just added a couple ATT apn settings still no data.any other suggestions?
By the way i have a 4g micro sim.Thought Tmobile S3 had ATT hspa+ bands.
Got apn settings from these forums.

Might want to do a lot of research before trying to flash an att ROM on tmo or vice versa. I heard the tmo phones are quad core.

did you flash an AT&T radio? you will probably need to do that.
how did you unlock your phone? did you just buy a code or did you try one of the XDA methods?

GS3 Tmobile LTE capable?

So I was in a tmobile store today and was told that both the note II and Gs3 will receive a software patch to enable the lte radio. Asked the question like 10 different ways as I've read online that the gs3 will NOT be let cab able.
the internal phone workings are a little above my head...but i was told that the tmobile sg3 is the same as say the att model which does have the lte radio,
So, does that sound right that the SG3 is future proof and will be able to enable LTE?

and that was from day 1? Obviously there has been debate about this on this forum and people much smarter than I have agued that it will never get LTE...
do you remember if there is something that has to be enabled? Or if say where I live they activate the LTE tower, boom it will work?

Its been a while so I dont remember the details, but I am convinced that
1. We will NOTget LTE one our GS3.
2. It doesn't really matter. By the time the majority of us get LTE in our market, we will have moved on to an even better phone! Also, most of us will get hspa+42 soon which for now is more than sufficient for almost everyones needs.

I think these threads need to be shut down. There are a number of other threads exactly like this that holds the correct information. Thanks Doc

I agree with Doc, we'll probably be on better phones by the time we have decent LTE reception -- and I'm happy enough with the DC-HSPA+ modem.
IMHO, they will likely release a Galaxy S3 [4G] LTE as an interm between the S3 and the S4. WRT LTE, all I know is what I see on Wikipedia's snapdragon article. Which isn't very clear on details. Also numerous MSM8960 phones /w LTE exist but do we even know if it's on die, let along bothering to crack open an AT&T and T-Mobile GS3 for a little hardware compare?

So afye reading this I have a question.... if you guys are saying that our phones arent capable then why on my phone (running frosty jb v7) are there 2 system apps called LTESettings.apk and LTETest.apk??? Are these not for our phone and are just ther e due to it being a port? And if so can I safely remove them so they are taking away ram and battery? Thanks in advanced

They serve no purpose to our devices so yes you can remove them. Just in case, make a backup first. Like move them to memory card or something.

Maybe I am the only one. LTE is not very efficient. I am happy with 3g+++.Tmo 3g super sized is a very good system. My company provided LTE hot spot sucks bandwidth like no other. Be careful what you ask for.

Yes, it can. Buy it outright and you can unlock it for free right away. But you will only get GPRS, if I am right.

I have an unlocked T889 running 4G (HSPA+) on AT&T. So long as you have a data plan it'll work. LTE radio is software locked for now, but really HSPA+ is fast enough for most uses and probably doesn't drain the battery as fast.

I have the TMobile SGH-T889...paid $25 to that cellunlocker cite, used their code with my AT&T HTC One X SIM in the Note II. It registered on AT&T, so I ran some speedtests with the Ookla app. I got test speeds in the 3-4Mb/s range, which in my area is as good as AT&T's HSPA+ network gets. The same SIM pulls the same speeds on my AT&T One X.
Conclusion, it works on AT&T 3G/fake-4G network no problems.
That said, the exact same phone, in the exact same location, with its TMobile SIM in it, gets 10-12Mb/s on the speedtest app. Not sure why I'd want to run the AT&T sim in this phone with that kind of speed difference.

Tmobile Note 2 On ATT Question

Hey guys a buddy of mine sold me his note 2 from tmobile. It is unlocked and working on my att service. My question is what can i do as far as the slow download speeds? I have LTE service and yes i know its not enabled on the tmo version yet but is there any way to get better download speeds? Flash a certain rom or flash a certain modem maybe? I wish the tmo version can be turned into a att version.....

What sorts of speeds are you getting exactly?

I'm getting around 1-2 mbps... is that normal on att hspa?

Wondering if I need to set the apns? I currently only see one option....

I'm not sure what the rules are on self bumping questions, but you waited 24 hours, which in my opinion is fine. Again, I don't know the rule, if there is one, but by my logic your actions were fine.
I wish I could help, I have the opposite problem. I have an ATT S3 unlocked, but I'm on T-mo. I only get EDGE. I'm selling the S3 on ebay though, I'll probably grab the Note 2. Although the March 15th "launch" of the SIV may make me hold off. Or get the Note 2 and use the return period to see if the SIV launches.
afaik the stock ROM doesn't have LTE built in, even on T-mo. Doesn't T-mo use the AWS split 1700/2100 for 4G too? That'd render the frequencies available non-compatible.

For sure hook me up. It works for voice, SMS and MMS, but EDGE only data speeds, which is SLOW. Hopefully someone will buy my S3 soon. Probably buy a Note 2 full off contract price and get the SIV when it's out with an upgrade price.

[Q] Enabling T-mobile LTE on an AT&T Note 2

Have an AT&T i317 unlocked with a T-mobile data sim.
I've done the tweak to enable the 3G/4G bands, a la http://forum.xda-developers.com/showthread.php?t=2068041
But now T-mobile added LTE in a few markets. I drove through one and suddenly got no data access. This is with "preferred network mode" set to LTE/WCDMA. If I switch to GSM/WCDMA, all is well (it sticks to the HSUPA and H+). So clearly it thinks it's on LTE but the phone can't access the T-mobile LTE.
I'm using Cyanogenmod 10.1, android 4.2.2, which also makes the model number show GT-N7105 instead of i317.
any tweaks to add the LTE? do i need to dump CM and use a diff ROM? do i need to go back to stock first to do any of this? (Right now, I can no longer dial *#7284#)
Thanks!

I am having a similar issue, I have a sgh-i317 with aws mod and the phone is not picking up t mobile lte even when placed next to a sgh-t889 that is getting it. Lte works with att sim but not working with tmobile sim. Any help would be great. I have tried many roms and modems and reflashing aws mod. Roms inculde jedimaster13/14 jedi x13/14 both att and tmobile versions and clean rom and stock 411 and stock 412
I figured it out see
http://forum.xda-developers.com/gal...2-sgh-i317-t2877487/post55453837#post55453837

Does the AT&T version have LTE? If it doesn't have the capability, but he modem is telling it to access it when it sees it, that might be why it dropped out completely. I'm mostly curious to see if AT&T LTE devices can use t-mobile's LTE network because I want to get an s4 active and I don't want to lose LTE by making that switch.

Try this for me, instead of that model number you have. Change it to the T-Mobile model#. Which is going to have to b done thru the build prop. Then reboot. Then go try and c if you pick up lte.
Because I just flashed a AT&T Rom on a T-Mobile GN2. And I pick up lte just fine with my AT&T SIM in there! And no AWS MOD what so ever. But the MODEM is still TMO, it'll always b TMO. Flash a att modem on a TMO GN2. Brick city.
Let me know what happens just curious!!
Edit: the Rom I flashed was SKY NOTE 9. No modem included!!!

WELL, here's your answer.
Maybe they getting the device at a cheaper price. Which would make someone but it. Instead of spending a lot more to have have the carrier brand you need. FYI
Both the phones are exactly the same. Besides the model# and done bloat. Like I said above, if it's unlocked it'll work, with both carrier's. So why not have that option to switch... and one more thing being able to take the phone internationally, and pop a SIM inside and ya have service. No roaming !!!
Just my 2¢® 2 you're question...

Att now has prepaid lte plan almost same as tmobile only .5 gb less of data everything else the same at 60 dollars . Plus att has better coverage well at least in the areas I frequent .

When a t-mobile version is available, I do buy it, but with ATT exclusives, that's not an option. For instance, I want the s4 active for its water resistance. T-mobile will soon offer the xperia Z, but when you compare the features and perormance, the s4 active is better, so for the money i'm willing to spend on a smartphone, i'd rather have the s4 active.. the hardware is capable of t-mobile LTE, but it still has to be configured properly with firmware and software to use the radios correctly. Since radios are some of the hardest pieces of firmware to alter, it's worth doing this investigation / collaborating to find work-arounds.

I didn't get tmobile lte on my at&t note 2 until I flashed the new at&t radio. That's all that had to be done. I'm using Skynote9 too. I did the aws mod again so I could get h+ 4g speed enabled and now is a flawless tmobile phone. Let me know if it works for you.
