Root [AT&T] No LTE after upgrade

[wiedhas]

AT&T GS3. I'm running cm10.1.2 and only have 4g (or sometimes only 3g) in known LTE areas. I'm on the I747UCDLK3 baseband which I think is the latest. I've got a GS4 next to me that's stock and getting 4GLTE service. Any ideas on what I can do?

Thanks,

NGH

when running a CyanogenMod ROM, 4G = LTE.

then the additional signals you can get is H+, H, 3G, and E.

No way! I googled the hell out of this before posting. Well thanks for not ragging on me. Hopefully this will help other wayward souls. Thanks for your help (and kindness).

Easy way to see is to go to System Settings > About phone > Status > "Mobile network type".

See, Samsung's TouchWiz uses the AT&T nomenclature which is 3G, 4G, 4G LTE, versus the AOSP (also CM, AOKP, PA, etc.) nomenclature which is 3G / H, H+, 4G (respectively). This is due to the rest of the world using standard nomenclature versus the US carriers who try to use marketing gimmicks to sound faster.

Summary:

AT&T | AOSP
3G = 3G / H
4G = H+
4G LTE = 4G
