Terrible service on unlocked 4.1.1 - AT&T Samsung Galaxy Note II

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

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

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...

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...

There is a way to unlock the phone but i fear that these roms are catered to 4g lte and simply mobile is only 4g will that affect service as far as data or email and text etc? Will it even work at all?

No lmao. If u dont know the difference between att radios and tmobile radios, then id advise u not to even bother with rooting and flashing. U can only get and will only get EDGE/2G data speeds. Period

I am having the same issue. Is anyone living in the dfw area on tmobile network having data issues? I go outside I get 15 mbps I sit in my house I get 300kpbs. Ive called tmobile and they are looking into it. But its been like this for almost a month now. You should call them and tell them whats going on. First call customer care and tell them the issue. They gave me credit on my account because why pay for something that dont work right then they'll connect you to tech support. Good luck. If we get more people to call in maybe they do something nationwide.

Where I used to get 1-2 bars with my g2x I get 0 with the note. Funny considering the size of the phone.

Calle tmobile and they didntdo anything . Could the pins of the sim entrance get messed up?

You don't have wifi ? because wifi calling is great...but conversely you might try turing your phones wifi off at the house and restart..I had a problem at first as the phone would jump off the gsm network and on to a bad wifi signal

No LTE signal in LTE area?

Hey everyone, was just wondering if something was wrong with my phone. My wife's phone was getting an lte signal with 3-4 bars while I was getting 4G only. I took the phone to the att store and my account is provisioned for lte and has the right sim card. Any help or advice would be great! Thanks!

Master reset and ask for a new sim card.

Yeah I have done a few. I would get about 9mb down and 1mb up. The phone status would read hspap:15.

Switch to airplane mode and then back to radios on. This will cycle your radios and LTE should come up. This is an issue that AT&T is working on for some devices. If that fails, call customer service.
Sent from my SAMSUNG-SGH-I317 using xda app-developers app
I was having the same problem, but not just no lte. In weak signal areas my phone would have no signal at all, not even for emergency calls, when my girlfriend's phone would have 3 bars of 4g. We even tried replacing my sim card. Luckily, I was within the buyers remorse period, and the at&t store replaced my phone. I do believe that this is some sort of hardware defect. Good thing you are still under warranty. Just call Samsung or at&t and they will replace your device.

(Q) best tmobile rom

Anyone know the best kernel, rom and modem to have for tmobile on the 317. I already am running cr 4.9 and saberkern on it.

Imo you're already running the best rom/kernel. If you don't think it's awesome then try something else.

On the same topic, can I get T-Mobile 4G on my 317? I didn't realize there might be a difference when I bought it. I haven't received my SIM yet, so can't test it. If I can't get 4G though, I'm going to have to sell this one and get a T-Mobile branded device.
I do think it is awsome. I was trying to get everyones opinion.

Mach you can enable aws on the 317 to get tmobile bands which will enable you to get 3g and 4g
