The $10-a-month T-Satellite service keeps you connected in areas without cellular coverage -- and you don't need to be a T-Mobile subscriber or buy a new phone to use it.

T-Mobile’s satellite service is now available to people across the US — and not just T-Mobile customers. On Wednesday, T-Mobile CEO Mike Sievert announced that the Starlink-powered service is officially out of beta, though it only supports text messaging and location-sharing for now.
