My wife and I shifted to Tmobile last year with the availability of the 5s. Sadly, our experiences do not seem to match up with the glowing reports on this board.... We frequently drop to Edge connections in areas that should be LTE service, and in many instances get 'no service' in places that you would not expect (Boston Logan airport, for example). Talked with the Tmobile tech support folks and they are blaming the phone, but given the fact that both of our iPhones have the same issues, am uncertain. On the road this week, in Pine Mountain, GA, and getting 'no service' at Callaway Gardens, occasionally getting 1 or 2 bars of Edge. Don't really want to go back to AT&T as I was hoping to actually use the iPhone tethering plan with Tmobile. Am wondering if anyone else has been experiencing this 'no service' or 'drop to Edge' situation?
