T-Mobile Starlink has officially entered the public beta phase. The long-awaited announcement came during yesterday’s Super Bowl game and according to the carrier, its direct-to-device (D2D) satellite service can deliver connectivity to the “more than 500,000 square miles of the country unreached by any carrier’s earth-bound cell towers.”

The beta phase will run until July. Afterward, you can decide if you want to pay for the service.
