In two weeks, you could be able to send a text message -- or even a photo, video or voice note -- from deep inside a national park or mountain pass. That's the future T-Mobile envisions, as its partnership with SpaceX's Starlink satellite service gets ready to launch on July 23. The alliance will provide direct-to-cell messaging service, called T-Satellite, which will also be available to AT&T and Verizon cellphone customers.
T-Mobile says its goal is to "eliminate mobile dead zones for good" by way of 657 Starlink satellites that'll be used exclusively for cellphone service. T-Satellite has been in beta testing since December 2024, with nearly 1.8 million users signing up so far.
The direct-to-cell messaging service represents a major step forward in mobile technology: It works with most phones made during the last four years, according to T-Mobile, instead of requiring dedicated hardware. It'll be available to T-Mobile, AT&T and Verizon customers for $10 a month -- or free for anyone on T-Mobile's Experience Beyond or Go5G Next plans.
"At the end of the day, it's nice to be able to send a selfie when you're in a place where there is no coverage, but it's vital to be able to connect to emergency services," Mike Katz, T-Mobile president of marketing, strategy and products, told CNET's Jeff Carlson. "We just think that with a technology like this, no customer should ever be in a situation where they are unconnected in an emergency."
However, you might still benefit even if you don't sign up, as T-Mobile will make the service free for emergency uses. The company said 911 texting will be available later this year to "any mobile customer with a compatible device, regardless of carrier or whether or not they are subscribed to the service."
What is T-Satellite?
T-Satellite is a partnership between T-Mobile and Starlink that will allow direct-to-cell SMS messaging accessibility in areas where there is no cellular coverage. Starlink has more than 7,000 low-Earth orbit satellites in the sky, and now, 657 of them will be devoted entirely to T-Satellite. The goal is to expand coverage into the 500,000 square miles of the US that traditional cell towers can’t reach, says T-Mobile.
“When you leave the terrestrial network and you go to a place where there's no network, your phone will automatically search for and connect to the satellite network, which is quite different than any other of the satellite systems that are out there that force you to manually connect, and you have to point your phone up to the sky," says Katz.
Satellite connectivity in cellphones isn’t exactly new -- iPhones have had it since 2022 -- but it’s typically been reserved for SOS messaging to connect you with an emergency dispatcher. On July 23, T-Satellite users will be able to send SMS texts on iPhone and Android. Android users will also get MMS immediately, with iPhone support “to follow.”
This means users will be able to send images and audio clips in addition to standard text messages. In October, the service will expand to include data support in third-party apps like AccuWeather, AllTrails, WhatsApp and X. The access takes advantage of hooks built into iOS and Android software, so developers can make their apps capable of sending data through the narrow amounts of bandwidth available via satellite.
