I'm in a real pickle. I have a AT&T (I747) S3 that's capable of LTE. I've flashed several T-mobile rom's on it and everything seems to work except I don't get an option to choose LTE in the Mobile Networks. I assume this is because T999 did not have LTE but T999L did.
Are there any roms that are touchwiz (I need wifi calling) and also support LTE?
Thanks folks!
Um... Why haven't you tried at&t ROMs if you don't have a t999* device anyway?

Because AT&T roms don't have Wifi-Calling feature. I should have clarified T-Mobile is my carrier.
I was able to figure this out. I downloaded this 4.3 Stock deoxed ROM for T999L and I was able to get everything working. Now onto theming it like an S5. Unfortunately majority of the custom roms out are for the T999 and don't support LTE. http://click.xda-developers.com/api/click?format=go&jsonp=vglnk_jsonp_14033932361886&key=f0a7f91912ae2b52e0700f73990eb321&libId=e2cc1c90-f9dd-49fc-b098-d6b1401acb32&loc=http%3A%2F%2Fforum.xda-developers.com%2Fshowthread.php%3Ft%3D2561670%26page%3D7&v=1&out=http%3A%2F%2Fwww.androidfilehost.com%2F%3Ffid%3D23252070760975307&ref=http%3A%2F%2Fforum.xda-developers.com%2Fshowthread.php%3Ft%3D2561670%26page%3D8&title=4.3%20Update%20for%20T999L%20now%20live%20-%20Page%207%20-%20xda-developers&txt=%3Cfont%20color%3D%22Blue%22%3ET999L_4.3_UVUBMK4_deodexed_KnoxFREE.zip%3C%2Ffont%3E

I still can't seem to get LTE on this AT&T S3 (/w AWS enabled). In the same area I'm able to pickup LTE on another AT&T S4 (/w AWS enabled). I'm able to pick up Edge and HSPA+ on both.
UPDATE: I was able to connect to LTE but I had to force the phone to use LTE Band 4 using *#BAND#. I was not able to make any calls at this point since it was the modem was running LTE only.
I then moved the modem to Automatic and the LTE remained and I was able to make some calls but on ending them, it went straight to Edge instead of HSPA+ or LTE.
The switch over between Edge to HSPA+ / LTE doesn't seem as smooth as the S4 and sometimes it just doesn't switch and sticks to Edge.
Ideas?
People have been trying to do this for a while and it is something I believe just isnt going to work. The I747 was built to use a specific set of frequencies on AT&T networks. T-Mobile uses different frequencies/bands and the I747 simply cannot make proper use of them. There's threads in AT&T forums about this. You should check them out.
I used an I747 before with T999 ROMs and had no problems connecting to LTE once I used the correct APN, can you please state what APN you are using?
Sent from my SGH-M919 using Tapatalk
Ok, I have realized that this is an error caused by the AWS patch going away when I reboot. I thought this wasn't supposed to happen with I747 and only with i747M's but it seems like it's happening to my unit.
Once I have the AWS patch on, it goes quickly from E - > 4G (HSPA+ - > LTE (when available). When the HSPA+ is only available, it has a much harder time moving from E-> LTE directly.

Oh I didn't realize you were using the patch.. Well my area is refarmed for 1900 hspa+ so I didn't have to use any patches, once I put in the LTE APN it quickly picked up LTE and everything was good

if you're only able to get Edge speeds on the ATT GS3 even after flashing a TMo Radio, then all hardware is not the same....it would mean that the actual radio hardware is different on their respective carriers. If you're still gettin edge speeds on TMo using an ATT S3 then that means the actual hardware doesnt have the required 1700 TMo 3g band...which is what I believe to be the case, if it works and I'm wrong then awesome but until someone confirms 3g speed on the 1700 TMo band then I'm gonna assume each carriers hardware is different...also something to keep in mind, those who flashed the TMo radio on an ATT Galaxy Note have reported bad battery life.

i didn't see a difference in my battery life while i had the note. + it was unstable at times due to the galaxy s2 being a completley different device.
There is a chance the S3 uses a different radio. I unlocked a One X this week & tried to get it to work on T-mobile. It did not pick up the signal . However, there are apparently two versions of the One X one with the 1700mhz band and one without. So it's kind of hit or miss on that device.

I flashed one of the T-Mobile Rom but in my baseband didn't change it is still have AT&T modem stuck in it. I am looking for t-mobile modem to flash over it and see if my data speed is improving.

I had the same problem with a Tablet from China. it only had the 850/1900/2100 band. T-Mobile needs the 1700 mhz band as indicated above and the 2100 MHZ band for 3G. I could only get Edge from the other bands in that modem on that tablet.
So unless the ATT device has the 1700 band, you can not get t-mobile 3G. There are many different modem chips with and without some of these bands.

I believe the hardware allows it to use 1700 mhz but it is now simply a matter of enabling it on the phone. Waiting on OP's results before I make my purchase this weekend and thankful that he is trying it out.
Best of luck from fellow Tmobile customers who are feeling cheated by the phone price!

It has been confirmed that an AT&T GS2 can work on T-Mobile AWS frequencies after replacing the baseband firmware with one from T-Mobile (and ensuring the device is carrier unlocked). I would assume then that doing something similar to an AT&T GS3 should also allow it to function on T-Mobile 3G or HSPA frequencies.
The hardware between the two devices are similar except that the SOC utilized on the T-Mo variant precludes LTE. Otherwise, the modems are functionally the same.
Doesn't work for the time being, i got unkown signal and phone refused to connect to network. Enabling it to work would require more than a flash of the modem.
More than likely the ATT device does not have 1700 band.
I need someone to crack this quick, it will influence whether i return the phone. Thanks for trying.

Won't work hardware not supported.
What do u base that on? The modem not working? That doesn't mean the hardware is not included. At&t's software could be programed to reject t mobile band modems.
Check this out, they're working on cross carrier compatible roms. These none at&t/touch wiz roms will eventually confirm whether it can be done.

I think the 1700 band is hidden really well if it's even there, so as of right now the hardware for the radio is not supported. Modems don't falsh over but Roms do, i am running a T-mobile rom right now on my i747. I tried flashing the modem and my phone wouldn't recognize any signal.
I dont know man. This chip was designed to be the mother of all frequencies. Then i hear the t mobile version may have a differnt chip and t mobile sayin they have no lte hardware.

I'm with rogers too. We'll my phone is. Anyhoo in order to get lte speeds with cm10 or aokp for that matter you have to put in that code looks like *#*#3896#*#* I'm not sure about the number though look around you'll find it, and then select lte, gsm. That's after putting in the right apn settings of course. Btw it'll work but it won't stick you'll have to do it again every time you restart your phone. Personally I can't be bothered that's why I stick with stock until they figure that out.

No need for all that. In latest CM10 all you have to do is change preferred network type to LTE/GSM/WCDMA, choose Rogers LTE apn and u get LTE speed. It will show 4G but if you do a speedtest you'll see the difference. And it sticks on reboot. In AOKP though it doesn't stick.

Looks like it is working now. I get 4G in the LTE area and H+ everywhere else. The data speeds are decent, so not going to worry about it.
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!

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...

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.

So you have a Tmobile T999 with an ATT prepaid sim?
I don't remember for sure so hopefully someone else can confirm, but I don't think the T999 can get better than 3g on ATTs network.
But if you're using the ATT sim, you'll be on their network so you may need to either unlock the phone and/or put in the correct ATT apn.
Sent from my SGH-T999L using xda premium
It will use HSPA on At&t no problem. Sounds like an APN issue. Your best bet is to go to the At&t forum and flash an At&t rom. Just make sure not to flash an At&t radio. Data should work out of the box on an At&t build.

This is correct. at&t uses the older HSDPA 7/14 and HSPA 21 depending on where you are located. They opted to go to LTE instead of a dual carrier configuration for their HSPA+
What service do you have with the prepaid att service? Did you have to get a new sim card? I looked everywhere on here, but didn't see anything
Hi all,
Just had a quick question, as I am thinking about swapping carriers from AT&T (horrible customer service and technical support). I currently have the AT&T i747, but I am thinking about switching from AT&T to T-Mobile as they are now providing Unlimited Everything for $70 per month. My question is, if I unlock my i747 for T-Mobile, which section in XDA would I go for custom ROMS, Kernels, tools and utilities and such? Would I stay here since the hardware is AT&T or would I need to migrate to the T-Mobile forums? Thanks in advance for your assistance.
In order to enable high speed data on you i747, you'll need to enable AWS frequencies on your s3 and unlock it. You could continue to use d2att ROMs if the model # on your phone does not get changed by using the T-Mobile mod.
You can use either sections, but you need to stick with i747 modems and firmwares.. And if you want to take advantage of T-Mobile's WiFi calling then you need a T-Mobile ROM.. You may or may not have to do the AWS mod. if you live in a refarmed T-Mobile area, then you'll get 4g and 4g lte fine, if not, then you may only get lte with edge being a fall back if you don't do the mod.. I used an i747 with T-Mobile and luckily my area is refarmed so I had 4g and 4g lte with no mods needed

Alot of people overlook the fact that T-Mobile uses which frequencies? Ones that are higher 1700+ mhz and someone like at&t uses 850+ the lower frequencies travel farther and penetrate walls and buildings. In my area if you get T-Mobile it os because you dont want to talk on the phone ever again...
Good luck
