Help! 3G is not working after Hard-SPL and unlocked TP2

I'm new here and I enjoyed this site very much. I have one problem with my TP2. Somehow, 3G network is not working after I installed Hard-SPL and unlocked T-Mobile TP2 switch to AT&T sim card. Everything is working fine with AT&T's sim card I was able to made phone calls, received, SMS, and web browsing. ATT 's 3G network is available around my home, but I can not get 3G on TP2 instead a EDGE network. Can unlocked TP2 handle AT&T's 3G network? or a .cab file I can download to fix this?

idk for sure but i think t mobile uses a different frequency for 3g from at&t so if they are you are stuck with edge speeds on at&t man sorry

I have the tmobile TP2 and i can confirm from talking with ATT that the phone does support ATT BUT i was unable to use the phone on 3g. The phone DOES support the signals for 3g but am still unable to access the towers in my area. I think the phone may be hard set to look at tmobile towers, is there any way i could reset the device to open up its tower usage? Hopefully i can get an answer but no tmobile TP2 users arent screwed in the US we just need to find a fix

It was my understanding that the tmobile tp2 does NOT have 850/1900mhz 3g on it. It does have aws 1700 for sure. Not sure about 2100mhz though for overseas.

This issue has been covered many times in the numerous AT&T threads on this board.
I'm sorry to tell you that the T-Mobile TP2 hardware radio was limited to using 3G over the 1700/900Hz frequencies, while AT&T currently uses 1900/850Hz only. It's unlikely that any change can be made to the radio software wise to fix this issue.
Just to make things clear the issue has nothing to do with Hard SPL or custom roms.

T-Mobile UMTS 1700/2100 Mhz
T-Mobile 3G runs on UMTS 1700 up and 2100 down. Unless you have a device that runs on those specific frequencies, EDGE is the best you can do with T-Mobile if you opt to run on their service.

ATT offers UMTS or 3G using 850mhz(the old TDMA band) and 1900mhz. While T-mobile offers HSDPA (technically 3.5g part of the UMTS specification) using 1700MHz for uplink and 2100MHz downlink.
Because HSDPA is part of the UMTS spec, it’s backward compatable. However, you have the limiting factor beging that the frequencies the individual carriers use to transmit the data.
Europe and Asia’s 3G runs on 1900/2100mhz. North and south America is supposed to use the (AWS) 3G spec using 1700/2100mhz
ATT didn’t want to wait, like T-mobile is doing, for homeland security to vacate those frequencies and launched on 850/1900mhz instead

I heard that t-mobile did not have enough spectrum in many areas to launch 3g in its existing 1900mhz. At&t doesn't have that issue, or as bad.

Im gonna make this real easy for u. The tmobile tp2 will not work on at&t 3g. The 3g bands are different

Telus TP2 Radio(s)

Exactly what cellular radios does this phone [Telus TP2] have?
My carrier [Telus] has recently completed their 3G overlay, and I'm still showing "EV".
Should I be talking to them about fixing this, or...?
It was (is?) my understanding that this phone was fully 3G capable.

Can someone help me with this?
As far as I can tell, my phone should support the Telus overlay of HSPA on their CDMA network, however I'm showing "EV" an my network type on the notification bar.
I visited a Telus store, and talked to a rep, who just babbled to me about how my SIM was "registered" as a CDMA phone, and therefore I couldn't use HSPA.
>_>
Thoughts?
EDIT: The rep also fed me this convoluted bullsh*t about how when I'm roaming, I'll be able to be on HSPA networks, so I'll get better bandwidth roaming than on my home network...

Wow no one knows the answer to this?
I've searched, and there's no answer, per se, just descriptions of Telus' technology and the antennae in the TP2, which seems to indicate that the TP2 should be able to get on the Telus HSPA network...

I have a SIM-unlocked Telus Touch Pro2 I bought off Craigslist, figuring it'd be good to go when the HSPA network rolled out (Only four months later!). As I understand it, the telus model can make and receive calls on quad-band GSM frequencies, but only use EDGE speeds for data. Has to do with the firmware for the chipset inside the phone. The only HSPA 3G band the phone can use is 2100 Mhz, which is the bad used in Europe, not Canada. It's a major piss-off, especially when a month ago the stores made this out to be the top-of-the-line phone, perfect for ever and ever.
It would seem that should Telus decide to plug in some firmware upgrades, they could activate the new 3G bands, but why bother? We've already signed away our souls to the company.
Who knows, maybe they'll fix it when they release Windows 6.5 for our rig. Because that's on the top of the to-do list, right?

Well there are new radios that we could flash...would that change anything?

Now I may be misinformed but I think that the Telus version is a CMDA phone with GSM capabilites on some frequencies. I do not think it will work on HSPA in Canada as they use different frequencies (850 and 1900). This is why so many people were waiting for the ATT version to come out as it uses those frequencies.
Remember GSM does not equal 3G.

What I would like to know is whether the distinction between 3G and GSM is on the hardware side, firmware side, or software side. Telus would have you assume it's all the hardware's fault, but I'm not sure on that one.

From everything I have read its the chip in the phone that isnt programmed/capable of doing the frequencies required. It may actually be a second chip but I cant confirm that. Other posts have stated that there wont be a software fix to "unlock the frequencies" needed.
GSM is a cellular line and 3G is a data connection.

I just purchased an At&t Tilt 2 unlocked for use on Telus 3G+ network. The Telus Touch Pro 2 is a CDMA , Quadband GSRM and UMTS/HSDPA 2100. The Telus TP2 will only work with EVDO data on the Telus network. If you unlock it for use with Rogers it will work on GSRM with Edge data. That is why I have ordered the At&t Tilt 2. Unfortunately Telus won't honour my unlimited data plan and say it is only for EVDO and that I have to change to one of their current plans to have HSDPA. Like all of the networks, they get your money one way or the other. I'm pleased that with the Tilt 2 I am free to switch providers here in Canada and still get 3G as well as when I travel in Europe.

T-Mobile Samsung Galaxy S II does not pick up HSPA in Europe, but my HTC G2 does, WHY

Hi guys, I'm currently in Europe right now, I have with me both my brand new TMO GS2 (I had TMO unlock it prior to my trip) but I also brought with me my trusty old TMO HTC G2 as a back-up phone.
I purchased a prepaid sim card here. Sim card already has the APN setting pre-loaded. When I pop it into my G2 I get full HSPA signal and getting 3 mb/s download on SpeedTest, but when I pop the same sim into my TM GS2, it only picks up EDGE with speeds of 200 kb/s download.
I did the "connect to WCDMA only" in the mobile networks setting and then I get no data at all, only phone signal.
I'm baffled since both phones has the same HSPA bands (HSDPA 850 / 1700 / 2100) actually the G2 doesn't even have the 850Mhz band.
Anyone have an idea whats happening and how I can get it to connect to HSPA? I'm here for a month and would really like to use my phone at full speed.
THANKS!

hmmm...That's really weird. What's the SIM card carrier?

TMO customer service has gone to **** over the last year, ever since they moved the call center to the Philippines, its just a bunch of under qualified and under educated clown working there. Last time I called in a tech told me to switch off my phone for 2 hours and when I turned it back on it would work. Seriously?
Anyways..
Orange, Romania is the Mobile Operator, which I'm pretty sure runs 3G on UMTS2100, which this phone has, and so does my HTC G2
My phone currently is running on the de-CIQ'd stock ROM that I got from the developer forum.
I assume the roms has the stock kernel and radio in it. Does the kernel or radio control mobile data? Could switching kernels or radios possibly solve this?
This is kind of a big deal no? I'm sure I'm not the only person that would like to use 3G overseas!

see here http://en.wikipedia.org/wiki/Orange_Romania
3G only on 900 Mhz or 2100 Mhz
so maybe the area you were in, did not have the 2100 Mhz tower, and only the 900 Mhz towers

Agreed this is most likely. 2100 is NEWER in most GSM countries.

I don't get any outsourced customer service. You're likely 1) Prepaid/Flexpay 2) calling in too much 3) showing out on the phone with the reps

but then I dont understand why my HTC G2 gets 3G?? would it have the 900mhz then even tho its not published?

I switched to Monthly4G service as ATT&T insurance...
This can only mean one thing then, the GSII was never supposed to work in europe, and that the HTC G2 and the HTC Desire Z have the same internals and are triband 900/1700/2100 phones.

Captivate Glide & Simple Mobile

Hi, I'm about to purchase the Galaxy Captivate Glide right now. I just had one question, will the phone work on Simple Mobile?
Simple Mobile is part of TracFone, which pretty much uses T-Mobile's for the Simple Mobile network.

I think, if you buy an unlocked version, that will be usable on any network.
It works on these type of networks:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100

Just called up Simple Mobile support and they confirmed that the Samsung Captivate Glide works on their network.

Note that it'll work on 2G EDGE, and on re-farmed T-Mobile 1900 MHz spectrum only.

StraightTalk may be a better option. I just got an i927R from NewEgg (Roger's version -- supposed to be unlocked) and it works great on StraightTalk, provided you get the AT&T SIM card. It will work on their HSPA+ network for "4G" (not true 4G).
Also, if you went through NewEgg as well, you may need to get an unlock code... It's apparently still locked to Rogers... It was only $9 for me (and I have a thread for a review on it) and it worked well. If you get a prompt for it, make sure you don't just "guess" something -- after three attempts, your phone cannot be unlocked anymore, apparently.

My brother has the AT&T version of StraightTalk for his Nexus phone, says it's great. I am considering going this route when the contract is up on my Glide (1 year to go from about now), but I thought about doing the T-Mobile version since they seem to have better signal at my house. That's unfortunate the Glide doesn't cover their current 3G (or fake 4G) frequency. Who knows, maybe they'll do more 1900 mhz by this time next year.

I am using an MVNO that runs ontop of T-Mobile. I am getting 4g on the Glide. This is because T-Mobile has started rolling out it's 1900MHZ network that is compatible with most radios on ATT phones. Lots of iPhones have been getting 3G on T-Mobile lately, along with both my HTC Vivid as well as my Samsung Captivate Glide.
I am in San Jose, CA.
http://airportal.de/ <---- I don't know if I'm allowed to LINK EXTERNALLY, however I'm not doing it for Advertising. This site has a map for sightings of T-Mobile's 1900MHZ network. You can add sightings as well.

Will i get the 4g feel with simple mobile on my glide ?

[Q] Verizon Note 3 on TMO

Hey guys, trying to get a Verizon Note 3 to work on TMO. I have a TMO rom installed in a safe strap, got it all running for the most part, but can't get data to work right. I used the TMO apn posted on TMO's website. When I switch from GSM only to LTE/WCDMA/GSM or WCDMA/GSM, I get no voice data or text. If I look at system status, on the mobile network state, it says Connecting, then Disconnected. And it just sits there and toggles back and forth. Any ideas? If I stay on GSM only, I have data, voice and text, but it's all on EDGE. Any input would be greatly appreciated!
I used this apn. http://support.t-mobile.com/docs/DOC-8373

1 of two things
1) Verizon model doesn't support GSM fully
2) doesn't support 1700mhz freq which T-Mo uses, it does support 1900 apparenrtly but you might not have that in your area.

If I switch to the Verizon stock rom, I can get HSPA+.
I was under the assumption (maybe incorrectly) that the phones for the most part were all the same. Could I try flashing TMO modems to see if it unlocks the 1700mhz band? I live right by New York city so I would imagine that I would have the better frequencies here.

It is NOT about unlocking frequencies. The phone itself is NOT sporting those frequencies. i.e. Hardware is not there.

Ok, I miss understood then. Thank you for the reply!

let's not forget to mention that one is CDMA (Verizon) and the other is GSM (T-mobile)... or unless I missed it and it was somehow implied?
