People familiar with the matter said when T-Mobile phones lose cellular connectivity, they will now first try to pair with SpaceX satellites. The initial rollout of the service is currently only available in the U.S., while Globalstar’s offering is available in multiple countries.

A major difference between the two satellite offerings is that the Globalstar ( GSAT ) service requires iPhone users to point their phones to the sky to help locate satellites. The report indicates that the Starlink service is expected to work automatically without having to adjust the phone’s location.

There has been speculation about whether Apple ( AAPL ) would offer support for additional satellite networks. After Apple ( AAPL ) announced a deal with Globalstar ( GSAT ) in 2022, SpaceX’s Elon Musk made a post suggesting SpaceX had been in talks with Apple ( AAPL ) about potentially offering Starlink connectivity.

SpaceX reportedly requested authorization to begin beta-testing the service on Monday.
