I have recently been trying different ROMs for my MetroPCS Mega and for the past couple of months I have not been able to get LTE to work.
I HAVE FOUND THE FIX!!
IT WAS SO SIMPLE!!
These are the APN Settings:
*The lib&nfc fix is intended touchwiz roms
For CM9/10,aokp, and any other aosp rom, just flash the desired version wallet as the libs and nfc apk are correct
latest Wallet version 1.5-r81-v4
important changes coming to google wallet on oct...
