Tmobile note 2 on AT&T - T-Mobile Samsung Galaxy Note II

So I bought a unlocked tmobile note 2 and I put my at&t sim in and all I get is the 4G signal...ive researched in how to get LTE..ive changed the apn. Ive tried doing it thru the dial pad and the menu pops up. And nothing. I even called at&t and asked them if they could help and they said we have to update your imei number and turn on lte for you..after that they said turn off my phone and turn it back on and I shoukd have lte...WELL I DONT!!! so any help would be greatly appreciated. Thank you

Is there a way to unlock this setting?
Search the forums. There's a way around it.

Golly thanks. Never would have thought of that. Any clues on which forums to search? The ATT forums pulled up nothing for me.
No way I've found around it.. don't know what he is talking about.

Search "GSLEON APN Unlock" in AT&T Development. I'd post a link if I wasn't on my phone.
Edit: Scratch that. Can't find it in there anymore. I'll see if I can dig it up.

Anyway if that is what you are talking about adding an non lte apn can be done but that is nit the same thing as unlocking it enabling manual network selection.

Is it something in the SIM that locks it?
i would greatly appreciate if someone found it!
What are you guys trying to do with this? When I go through it seems to be unlocked I can choose att and T-Mobile and I'm on att network

Where did you get the phone? I'm guessing from your sig you are rooted and running a non-ATT rom?
if you are talking to me i got my phone from att and i am using my att rom

Is that all it takes? Coolio. What is the best way to unlock? Also, I'm not worried about LTE vs 4G , just carrier selection.
oh im not unlocked either phone is just rooted running my rom
Would unlocking get carrier selection working?
I'm not sure I have carrier selection and I'm not unlocked

Just rub a little salt in the wound why doncha... lol. That is where I wanna be. I get into areas where the ATT signal is weak but present, and the phone will go on a roaming network. If I reboot it comes back up on ATT. Might have to go the root/rom route. Unless unlocking will get me there...

Unlock code?

If my phone is still under contract can I still call at&t to get the unlock code?
I've been with at&t for over 2 years

Try telling them you will be traveling internationally to a specific country for several months for business or school (I like New Zealand ) and would like to use a local carrier's service with your phone while there. They might grant you an exception. If you are on contact those terms will still apply. Good luck. :thumbup:
Edit .. Or you can use the unlock method noted above... That worked for me

Now I'm on the hunt for a downgraded ROM...I found a stock 4.1.1 ROM but can you flash a actual stock ROM using cwm or do I have to use Odin and unroot?
Sent from my SAMSUNG SGH - I317 using xda app-developers app
You only need to flash the older modem (from same model phone), then flash back current modem. Search this forum.. You will find cwm packages for this.

No & no. All you need to do is downgrade your modem perform the unlock. Then reboot, then re-flash the latest modem back on the device!
Here's the first AT&T modem release:

I'm give you the first release. But you'll have to do some homework and find the newest modem. To flash back on your device.

Just use the unlock method posted on this forum. Worked for me.
Actually I read by law some carriers have to grant you if requested a unlock code...
It has to be least 6 months in contract nothing less.....And if they argue and so no..ask for supervisor. ..he he still does not give it to you ASK FOR A CLAIM TO CORPORATE. .I got a unlock code within 15min.....from corporate giving me mine...I was actually still on the phone with att supervisor when he filed a complaint and mailed corporate. ..I didn't answer the other line, , but I checked it and sure enough they gave it to me without any issues....tell them you travel...they need not more then that....it works belive me..I dont this to every phone in past 3 years every 6 months

You need to change your APN to the ATT LTE and make sure it's set to LTE/GSM. Got a friend's T-Mo S4 up and running on ATT.. everything works flawlessly.

If you "found" it, then yes you should do the right thing and try to get it back to them. In any case, if/when the owner reports it as lost or stolen, the IMEI would be blacklisted and you'd have a useless GS4.
Yeah that's true. Well it don't matter i got my nexus 4 and Motorola Atrix HD all running official CM10.2

How did you get it unlocked so fast, through T-Mobile? Just wondering, I also paid full price for mine.
Does the T-mobile Note 3 have the 850 MHz LTE band (like the ATT one does)?

I guess it does cuz I'm getting att LTE on the Tmobile note. I used cellunlocker.net and got my unlock code in about 15 minutes for 25.00.

Terrible service on unlocked 4.1.1

Phone is originally att and I unlocked it by flashing 4.1.1. I hardly ever get service in my work building. And service switches from e to 4g way to much. And I miss calls all.the time. Like ill have service but phone will not ring. What can I do to fix this. I love the phone but its impossible to use for original purpose
Sent from my SAMSUNG-SGH-I317 using xda app-developers app
You sure you have signal service with any ATT phone at your work place?.
At my work place i had to switch to Plane mode because it was no to 1 bar service which can't make/receive any phone calls and it happened to all ATT coworkers phone.
Yes im on tmobile. But my nexus 4 would have excellent service here. Not really good data. But phone reception yes
Sent from my SAMSUNG-SGH-I317 using xda app-developers app
Did you flash the AWS mod (I believe thats what its called). It should allow your phone to use another radio band used by tmobile.

You know you can upgrade your modem to see if your reception will improve? As it should with a newer modem release...
