I'm in a real pickle. I have a AT&T (I747) S3 that's capable of LTE. I've flashed several T-mobile rom's on it and everything seems to work except I don't get an option to choose LTE in the Mobile Networks. I assume this is because T999 did not have LTE but T999L did.
Are there any roms that are touchwiz (I need wifi calling) and also support LTE?
