Try getting a new sim card

Just got back from bell, the card was switched and still no network. I'm lost, i might just start with a stock Odin flash and see how it goes. Any other ideas? I won't be able to do that till mid week.

Have you tried checking if you still have an imei number under phone status? But don't post the imei number.

Data doesn't seem to be working 100%.

Sometimes my data stops working even though it is still checked in the settings. I haven't reached the data cap either. Its at around 3GB so far. Any ideas as to what this is? Any help would be appreciated. Thanks!!!

I just got a new sim SIM card from T-Mobile. I'll update this later and see if that was the problem.
Ps - Every ROM I was on, I had this issue so it wasn't the ROMs because I used the same ROMs a while ago with no data problems.

Seems to be working a lot better with the new SIM card replaced. Hopefully that did the trick.

settings-> mobile network -> network operators

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
Sent from my SAMSUNG-SGH-I747 using xda premium
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...

I need the sprint radio to flash to my phone.

Things went south when I accidentally tried installing the wrong rom. restored back, but now I can't connect to my sprint network.
Look up rwilco. He has all the modems in his repo

Thanks. took me a few to find it, but I did. Got cell phone coverage back, but no data at the moment. About to try one other modem and then try switching roms again after that.
Seems I'm more screwed than I thought. Phone Number is showing up as 000-000-3891. Network says Samsung and not Sprint. Mobile Network state is disconnected.
Did you restore with odin?

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

Rom suggestions. APN settings? Metro pcs

Hello there.
I just unlocked and rooted my t999.
I will be using it with metro pcs, can anyone recommend any roms good to use with metro pcs? Or can I just stay stock? Is it safe to delete the t-mobile apps? What APN setting should use for data, mms, sms and voice to work properly?
Sent from my SM-N900T using XDA Premium 4 mobile app
You can use any rom or stay stay stock, up to you, and yes you can delete the T-Mobile apps.. For the APN, the T-Mobile APN will work fine

I'm sorry I don't know why I keep saying metro pcs, most metro pcs retail stores in my city changed to AIO wireless, so I'm getting AIO not metro, they told me it's the same as at&t as they are working with the same towers, so you think I have to change the APN from tmobile's to at&t? Or AIO?
Sent from my SM-N900T using XDA Premium 4 mobile app
You would have to change it, but I don't know if at&t APN would work. As far as ROMs you can also use at&t ones as well

If you call T-Mo, they can tell you if its blacklisted. If it is then it will not work.
It is blacklisted and it worked right when I inserted the AIO sim card, I just had to enter the APN for data to work.
