First of all, sorry if I posted this in the wrong forum or if it has been asked somewhere already, but I was not able to find it anywhere though Google and searching through this site.
Anyways, I was wondering if it is possible to fully and effectively unlock a AT&T S3 to use on the VZW network. I know vzw has a secured cdma network that only allows approved devices but with all the great devs out there, is there some wah to do it? Thanks for any input !

I don't think you can do that as Verizon uses different lte bands and two its cdma network even tho it uses a sim! I could be wrong but I know it can only work the other way round but thats only on 3G tho

I have the same problem except the other way around...I want to convert a Verizon one to att. I already flashed a AT&T rom and have working voice and data, but only 2g which is so slow, I don't even remember how I lived with it. I'm thinking of just buying a motherboard from the att one and sticking it in my Verizon one. Does anyone know if the motherboard has the part I need for the radios, or is the radio separate?
Sounds easier to try to do a trade on Craigslist or something.

I've also running on EDGE connection, which is horrid, but livable. Due to thaat I'm running a T-Mobile network on a Verizon S3.

Can anyone confirm that this works on att network? Even on tmobiles website it says it supports the 850 band but i saw a report on engadget that they were having trouble connecting. Can anyone tell me if this phone has a locked bootloader? As of now i have an atrix but i would prefer vanilla android.

It currently only supports ATT 2G. The hardware is capable of 3G but the bands are blocked out. There is some hope they can be enabled via a software fix, but I wouldn't hold my breath.

This is typical for carrier phones. Of course they don't want to sell a phone that works great with other carriers. The Phone supports the bands but the radio/software is blocking use (per Tmobile). It was already quoted that Tmobile will unlock the AT&T 3G once the merger goes through.
The bootloader is unlocked. We already have root and Clockwork Recovery setup on stock Android. LG has even already released the source for the kernel. CM7 is also already on the phone but not quite prime time.
Once custom roms are published, we'll be good to go. Coming from a Nexus One, I'm glad this phone is just as open.
I'm sure someone will unofficially enable the at&t 3G, just give it a little time.

Well no big deal anymore [email protected] I just cancelled my att plan and joined tmobile to get this phone

The service manual clearly states that the phone only supports WCDMA FDD1(2100) and FDD4 (1700). Theres no mention of WCDMA FDD5(850) anywhere, not even in the block diagrams of the RF circuits.

Sorry if this is redundant folks, but a friend of my stepfather has been having some issues. He recently purchased a G2X, used it for a month or 2 on T-Mobile, but now wants to switch to AT&T with his girlfriend. He's gotten pretty far, getting the IMEI from T-Mo and getting it actually unlocked. He's now got Calls and Texts up and running on AT&T's network, but he can't get any data to work. We know that 3G won't work on it, but we assumed EDGE would.
Any help here? I'm sure it something reasonably simple.
Please and thanks, XDA!
There's a thread in the SGS2 dev section with AT&T's APN settings. They probably need to be changed in the phone.
Mine is unlocked and I tried my wife's at&t sim and had no issues connecting to internet. Not that that helps you, just wanted to throw in my experience. I wonder if it makes a difference which type of rate/data plan the at&t sim is on.
G2X CM7
Thanks Barry, I found that thread and sent him the APN settings. I'll post back tomorrow with results.
And thanks for your input phburks. The reason why yours worked may be that you're running CM. Our g2x is running stock Android.

Hi,
I've really been looking around to get myself a new phone to use on tmobile.
I was just wondering if using a T959V modem on an infuse would bring the ability to use tmobile's 1700mhz HSPA bands.
lemme know if you any of you guys are doing this.
Thanks,

I know the modem can disable certain talk freqs but I think because T-Mobile data freqs are so unique to tmo that other phones just don't support them. it could also be in the ril or even antenna tuning. I've never counted it out but figured someone would have had it figured out by now. I don't feel like getting a tmo sim card just to try it out.

No, it's a hardware limitation, not software/firmware, you'll only be able to utilize EDGE data/gsm.

might be a while before I try so don't hold your breath...
the thing that is weird is good devs have said it'll never happen. what bothers me is the ril,and modem both work and the chip is the same. now Im no expert on wireless or antenna design but antennas can be tuned and its posible there are separate antennae for different freqs not just differt types of connection. there may also be something else needed to support T-Mobile aws but I have a hard time believing its a hardware dependency and not a firmware/framework dependency other than the antenna just being inefficient... but there may be some supporting chip or something. nobody really knows. all we can do is use as much T-Mobile firmware as possible and hope its not a kernel dependency or hardware. I know I don't have the skills for the kernel and if its hardware its a waist of time.
So as for now there is no progress on this field?
Do not really want to change my Infuse especially when there are no good phones for TMobile except HTC One S(((
Looking for a way to update my own PRL running on the Sprint network. I have my MSL and already enabled the other LTE bands so I know that functions correctly. Thanks!
I am wanting to do this as well. Dial codes work but i cant find the one to write the prl. On samsung TW roms its ##DATA## but that dosnt work here. I tied *#*#data#*#* and that shows some menus but none to wright the prl
Seems like I remember seeing that there is a SprintHiddenMenu.apk that ships with the phone. Do you see it in /system/app? Not sure if it will have a PRL update option, but might be worth a look. I'll be using mine on Sprint too, so I'd be interested to know what you find.

I wouldn't be surprised if sprint hasn't had enough of your 00001 prl flashing.
Anyone figure out how to do this? We need diag mode, diag driver and probably a new version of qpst.
Sent from my Nexus 5 using Tapatalk
Definitely still looking...I saw they figured out how to do it with the LG G2 so since this phone is loosely similar I imagine the process should be close. The G2 has to have a diag mode enabled...I really think the key is figuring what dialer code this actually is.
Looking forward to this too. LTE keeps breaking after 30 seconds or so, not that the speeds are any good in Chicago anyway. Can't wait to do some Verizon roaming. Being stuck on Sprint 3g is not ideal.
Yeah but the problem is the LG G2 does not have the same software. This phone isn't only built for Sprint so I have a feeling it will be more difficult.
Sent from my Nexus 5 using Tapatalk
It is built for Sprint. That's why it works on Sprint. It's capable of running on every network short done lte stuff with Verizon. It won't run Verizon as a primary but does roam there. I'm sure there is a way just weather or not you will have to use cdma tool to do it.

Has there been any new info on this? My girl is almost about to activate her Nexus 5 (once the sim card arrives). But really need to be able to force roam or at least use 00001 prl.
Bumpity Bump. You guys figured anything out yet? Would love to use the corporate PRL for actual 3G roaming.
Bump :X
Hoping someone finds something soon. I always roam on Verizon at my house but my plan only lets me use 1x... Need dat 3G xD.
I'm running 4.4.2 on my LG G2 for AT&T
My wife just got the same phone and her phone shows 4G/LTE Mine shows only 4G
I checked our APN settings for both and they're the same
I checked through the 4636 code through the phone and it shows only the HSPA letters where hers shows up once again with LTE
ANY advice would be great
Try turning data off then on again, it will force it to search for the network.

i tried that one...and i tried the 4646 code and theres no option to change the NETWORK type...this friggin sux...no LTE on this phone and only "4G"...been tryng to figure this one out..
any advice much appreciated.
Maybe replace it?
If this is a new phone that you haven't tampered with, I suggest that you exchange it. New phones don't need any change in settings to connect to LTE out of the box.
Maybe it's a hardware problem. Did this problem just appear out of nowhere? (maybe after the update)?
Like the poster above if its stock return it otherwise reflash to stock to confirm the issue is still there, here's another thread dealing with the same issue http://forum.xda-developers.com/showthread.php?t=2702386

you might be 'ROAMING'
this happens to me. i think theres no att tower near me, i think they use someone elses lte tower, but half of the android phones ive used need roaming enabled to connect to lte in my area. try that it might work.. its in the normal settings app under networks enable all roaming. never had any extra charges. att covers the nation and doesnt count local roaming.
BUT i agree with this guy if my suggestion doesnt work
