Although T-Satellite is a T-Mobile service, US users on rival carriers can access the satellite connectivity too for $10 per month. Here's how it works and how to sign up.

T-Mobile's T-Satellite internet service, powered by SpaceX's Starlink satellites, officially launched on Wednesday, July 23. The direct-to-cell messaging service that enables texting from anywhere isn't limited to T-Mobile customers -- AT&T and Verizon mobile customers can also purchase it for $10 a month.

T-Mobile T-Satellite service is now out of beta testing and is available to all US smartphone users, including AT&T and Verizon customers.
