I just purchased a factory unlocked Lumia 1520, inserted my AT&T sim and most functions work except I can't get LTE, or tethering to work. The phone displays H and alternates to H+ sometimes. All works when I put the sim back into my old phone and I get LTE in the same spot.
I've spoken to AT&T and they claim to have reset the sim OTA but still nothing. :unhappysweat:
Any suggestions from the community ?
