The T-Mobile T-Satellite service is now ready for prime time, as it launches out of beta nationwide on July 23.

T-Mobile announced the T-Satellite launch as part of an event to mark an award from third-party testing firm Ookla that names T-Mobile the best phone network in the U.S. It's quite a turnaround for the carrier which found itself ranked last in network performance surveys a dozen years ago.
