SpaceX last night launched the first six Starlink satellites that will provide cellular transmissions for customers of T-Mobile and other carriers.

SpaceX said it launched 21 satellites overall, including "the first six Starlink satellites with Direct to Cell capabilities that enable mobile network operators around the world to provide seamless global access to texting, calling, and browsing wherever you may be on land, lakes, or coastal waters without changing hardware or firmware. The enhanced Starlink satellites have an advanced modem that acts as a cellphone tower in space, eliminating dead zones with network integration similar to a standard roaming partner," the company said.
