Good to know, my signal is spotty. I work near Tampa International Airport, but live in wesley chapel. Screen says 4g or 2g, i've never seen it say 3g. At home most of the time it's on 2g, which is lame my gs3 was always on 4g and had better signal.
Overall however, tmobile service sucks, I was long time sprint person, not that their signal was the greatest, but def better than tmobile. Once I leave tampa, I lose just about all signal between here and Atlanta.
