SpaceX and T-Mobile are teaming up to offer mobile phone service to mobile users via Starlink satellites, the companies announced.

This service will be especially useful in areas where there is no cell coverage, especially in emergency situations, SpaceX founder Elon Musk said at an event in Texas.

SpaceX and T-Mobile said the new plan will bring near-complete coverage to most locations in the U.S. — even to many of the most remote locations previously unreachable by traditional cellular signals.

The service is expected to launch next year, when T-Mobile will use its mid-band spectrum to build a new network, T-Mobile CEO Mike Sievert said at the same event. It will work with most phones and the text service will be launched first, he added.

Musk also made the announcement on his Twitter, saying the new service aims to "remove dead zones around the world." Tesla cars will also be able to connect to the new Starlink satellites, Musk said in response to questions about the feature.

SpaceX's Starlink satellite was originally designed to provide high-speed internet to people living in rural areas with poor coverage. It has a user base of over 400,000 subscribers worldwide and over 2,800 satellites in low Earth orbit.

On Thursday, Starlink prices dropped for some users in the UK, Mexico, Germany and the Netherlands, reports The Verge.
