no he got it from experience. You honestly think AT&T has the best coverage everywhere? What if there's a building in the line of sight of the tower and his house but Verizon has full bars?
Where I'm moving AT&T has zero data and very little voice coverage and Verizon and Sprint have 3g. Should I keep AT&T because Luke Wilson says so or should I go with experience?
Go with Rodimus Prime's 2 step process.
I was talking about the particular area and not about having best coverage everywhere. Every carrier has its good and bad locations.
I traveled thru many places in MA and never had any problems with full 3G signal and proper coverage.
