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

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!!!

I don't have any solution for the question but I do have a question of my own.
Why do I keep reading of people buying att devices for t mobile, why not just buy the t mobile version?

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.

Hello guys. I'm on a roadtrip trip right now in usa for 3 weeks and bought a sim and plan for 70$ from tmobile worst service ever. They told me I will have 4g from Oregon to vegas on i5 highway... So not true all I was getting was edge and g. I was wondering if att is better if I have note 2 T889V would it get data with att prepaid? Some lady at att said I won't have Internet at all. Not sure if it's true or not. Just wanted to clarify it with you smart guys.

Tmobile does not have the signal coverage that Verizon and att have.
As for you question, as far as I can tell, it may be possible to flash att radio on your model n2: there has been 1 report that someone has succeeded but no confirmation and no how-to. Others tried and either didn't work or bricked their phone.

Not possible without changing radios? To use Att?

ok is there a rom that work right out the box for some sort of data with my prepaid at&t sim card i can make calls get mms, but cant get data i really need some sort of data working today i am rooted, unlocked and have no idea if i should be useing some sort of at&t kernal, or just changeing the apn, which has not worked yet?
can some one please direct me to the right thread or something
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.

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.

I think it will use HSPA+ but only difference is that att hspa+ is not 42mg like on tmobile. I was getting around 7mg with my friends att sim on my t999.

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
When I got my note 4 I switched from T-Mobile to sprint.. can we use T-Mobile Roms? Also are there one like 2 devs usually for sprint? There forum looks way different than ours.. so many options.. just wondering since im a new sprint user.
As far I know you cannot, must be Sprint. Device is different, network is different.
Haven't really read all the way through but apparently you can with kernel and radio issues

Is there a prepaid service that is compatible with Verizons Note 4? I'm just wondering because I keep looking around the Web and maybe I am missing something but I haven't found any leads on it. If anyone can chime in it would be appreciated.
Straight Talk with a Verizon sim, PagePlus, ROK Mobile with a Verizon sim, and Verizon Prepaid are all compatible
My Verizon Note 4 works with straight talk at&t sim also. Shows 4glte. Off topic But my T-Mobile note 4 also works on the at&t sim with lte
I'm using Verizon prepaid on my Note 4 right now
