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 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 new satellite texting 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. While it’s available to all T-Mobile, AT&T and Verizon customers for $10 a month, anyone on T-Mobile’s Experience Beyond or Go5G Next plans gets it for free.
«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.»
Sadly, T-Mobile has already had a reason to test out this emergency service, when it enabled T-Satellite earlier this week in communities affected by massive flooding in Central Texas. T-Mobile customers in the area are able to use text-to-911 and basic text messaging, and they can receive emergency alerts on compatible devices.
In the future, T-Satellite will be free for emergency uses across the country. 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.
This is far beyond what the other phone carriers have launched so far in the satellite realm — largely due to T-Mobile’s partnership with Starlink. AT&T and Verizon have both partnered with AST SpaceMobile for satellite messaging, and Verizon told CNET’s Eli Blumenthal last year that it’s still planning on working with Amazon’s Project Kuiper, which launched its first 27 satellites on April 28, 2025.
«Despite things that our competitors have said, they are way, way behind on this technology,» says Katz.
How much does T-Satellite cost?
T-Satellite is available to AT&T, T-Mobile and Verizon customers for a standalone $10 per month. But there’s one exception: Customers on T-Mobile’s Experience Beyond plan ($100 per month for one line) or the Go5G Next plan will get the service for included in the cost of the plan going forward, and those on the Experience More plan ($85 per month) will get it through the end of the year.
Even if you don’t pay the $10 a month, T-Mobile says 911 texting will be available later this year «to any mobile customer with a compatible device, regardless of carrier.»
If you’re a Verizon or AT&T customer, you’ll have to activate T-Satellite as a second eSIM on your phone to take advantage of the service. You can find instructions on setting up the eSIM here.
