I've had my Motorola Razr M for what seems like a decade now.. I have always read that Motorolas have the best antennas and I can vouch that out here in Colorado I can make calls in places that most other people can't.

Alas the limited onboard memory and the increasing size of the OS over the years has turned the old Razr into a boat anchor so I'm looking into the Motorola Z Turbo 2.
