Have you tried powering down, reseating your SIM card then powering back up?
Also the E means you are running on Edge which is a slower internet connection than 3g.

Try going to settings> more settings> mobile networks> network mode> Set it to LTE.

Your device may not have these settings but check anyway

I set up a new APN and reboot my phone and the 4g works for a while then turns off. Also of I turn off the WiFi and turn it back on the 4g signal goes away as well

Did you use the right .tar file for your phone?

I'd also try doing a full restore and see if the problem persists.

 

[FUBAR1991]

Could it be because I've get four APNs that the phone is just decting the best one?

Edit- full restore on the phone to factory settings or a unroot then back to default?

Do you have the AT&T LTE apn set up? That's the apn AT&T uses for most of their hspa+/LTE connections now I believe. Plus if that isn't working the rom might of gotten a little messed up. Try and see if a factory reset will fix it

Still having the same problem. Im using these APNs http://forum.xda-developers.com/showthread.php?t=2235570 I'm going to keep messing with it.

Edit- in settings EVI version is blank is there supposed to be something there?

That's the correct LTE apn. I've have no idea about the emi or whatever it is. Have you tried a custom rom? I have a feeling that might help fix it if you were going to install one anyway. You said blue tooth wasn't working as well, is your wifi working? If that isn't then you probably have a corrupted modem driver

Wifi and Bluetooth are working fine. Do I install a rom the same way. I rooted the phone in clock work recovery mod. What is the best rom

Installing a rom didn't fix it.

Interesting. Well, the easiest way to fix the problem is flash the stock image from when it came from the factory. You will lose the root, and go back to the stock rom. If you want to keep troubleshooting we can but this will fix the problem for sure if it really is affecting your phone in a major way.

My S3 is still on ICS I try and update it and it says my phone is up to date. If I just call ATT will I still need to unroot my phone?

I believe you would have to unroot and return to stock to update
