T-Mobile yesterday announced more details of its new service powered by Starlink and said Verizon and AT&T customers can use the satellite offering, too. The standard price will be $15 a month as an add-on for T-Mobile customers, and $20 a month for people who don’t have T-Mobile as their primary carrier.
While we’ve written numerous articles about the Starlink/T-Mobile collaboration over the past two and a half years, the service’s beta test and a Super Bowl commercial are raising awareness that it exists. In this article we’ll answer some questions you might have about T-Mobile Starlink (yes, T-Mobile Starlink is the official name of the service).
What is this thing anyway?
Over the past 13 months, SpaceX’s Starlink division has launched about 450 Direct to Cell satellites that can provide service to mobile phones in areas where there are no cell towers. Starlink is partnering with cellular carriers in multiple countries, and T-Mobile is its primary commercial partner in the US.
T-Mobile says the goal is to provide telecom service in dead zones, the 500,000 square miles of the US that aren’t reached by any terrestrial cell tower. When a user crosses into a dead zone, their phone is supposed to automatically connect to Starlink satellites. T-Mobile Starlink only supports texting for now, but T-Mobile says voice calls and data service will be available eventually.
Who can use it
T-Mobile Starlink is obviously available to T-Mobile customers, but the carrier said that Verizon and AT&T customers can also use it on their existing phones without switching entirely to T-Mobile. Verizon and AT&T customers will need an unlocked phone with eSIM technology, which lets users activate a cellular plan without a physical SIM card.
A Verizon or AT&T customer can use T-Mobile Starlink by activating a second eSIM on their device. “They will technically be assigned a T-Mobile number, but that’s just to provision the device to access the constellation. And then the second eSIM can connect whenever the user loses coverage,” a T-Mobile spokesperson told Mobile World Live.
T-Mobile suggested that international roaming will be available with other carriers that also partner with Starlink. T-Mobile said a “growing alliance” of telcos “aims to provide reciprocal roaming for all participating carriers.” Participating carriers so far include ones in Japan, Australia, New Zealand, Switzerland, Chile, Peru, Canada, and Ukraine.
How to sign up
To use T-Mobile Starlink now, you need to register for a beta trial and hope you get in quickly. “The beta test is free and open to anyone—on any carrier—until July,” T-Mobile said.
There is a short registration form in which you’ll provide your name, email address, and mobile phone number, and agree that T-Mobile can contact you with marketing offers by email or phone. “We’ll admit people on a rolling first-come, first-served basis, so we encourage everyone to sign up as soon as possible,” T-Mobile said.
T-Mobile said it is enrolling users “on an ongoing basis to help test the system and provide feedback before launching in July.” Beta registration began in December. Early reports from beta testers suggest the service usually does what T-Mobile claims—enabling texting in areas with no cellular access—but that users still can’t get connections in some areas.
What it costs
When the free beta trial ends, T-Mobile customers will be able to add Starlink service to their plan for an extra charge of $15 per month for each line. If you sign up for the beta during February or if you signed up before then, T-Mobile says you’ll get a $5 discount for early adopters once the service transitions from a free beta to a paid add-on. T-Mobile users with the early adopter discount will pay $10 a month starting in July 2025, the company said.
Go5G Next, T-Mobile’s priciest plan at $100 a month for a single line, will include Starlink access at no extra cost. “The beta is free until July at which point T-Mobile Starlink will be included at no extra cost on Go5G Next (including variations like Go5G Next 55+), T-Mobile’s best plan,” the company said. “Business customers will also get T-Mobile Starlink at no extra cost on Go5G Business Next, first responder agencies on T-Priority plans and other select premium rate plans. T-Mobile customers on any other plan can add the service for $15/month per line.”
After the beta trial ends, Verizon and AT&T customers can purchase T-Mobile Starlink for $20 per month for each line. There was no mention of an early adopter discount for customers who don’t use T-Mobile as their primary carrier.
Users who aren’t subscribers of any of the big three carriers can also take advantage of the $20 offer. We asked T-Mobile if it would be available to people on other carriers, such as regional wireless providers or resellers. “Yes, any wireless user with an unlocked eSIM phone can sign up for service, regardless of provider,” T-Mobile told us.
Which phones it works on
T-Mobile Starlink works on recent iPhones and certain phones made by Google, Motorola, Samsung, and a T-Mobile brand called REVVL. T-Mobile said more phones will be added over time, and the current list of supported devices is as follows:
-
- Apple iPhone 14 and later (including Plus, Pro & Pro Max)
- Google Pixel 9 (including Pro, Pro Fold, & Pro XL)
- Motorola 2024 and later (including razr, razr+, edge and g series)
- Samsung Galaxy A14, A15, A16, A35, A53, A54
- Samsung Galaxy S21 and later (including Plus, Ultra and Fan Edition)
- Samsung Galaxy X Cover6 Pro
- Samsung Galaxy Z Flip3 and later
- Samsung Galaxy Z Fold3 and later
- REVVL 7 (including Pro)
Going beyond text
Moving from text messages to voice and data requires more bandwidth, and SpaceX needs another government approval to use the full capabilities of its satellites. To that end, SpaceX is seeking a waiver of Federal Communications Commission rules regarding out-of-band emission limits.
Verizon and AT&T urged the FCC to deny the waiver request, alleging that Starlink’s plan would interfere with services provided over networks using adjacent spectrum bands. SpaceX has described the waiver as being crucial to its future plans, telling the FCC that the “out-of-band emission restriction will be most detrimental for real-time communications such as voice and video, rendering such communications unreliable both in critical and in common circumstances, increasing risk in emergency situations.”
The FCC approved Starlink’s plan for cellular phone service in November but deferred making a decision on the waiver request.
Verizon and AT&T plan similar service
AT&T and Verizon both intend to offer similar service through deals with satellite operator AST SpaceMobile. But AST SpaceMobile isn’t as far along as SpaceX’s Starlink, which is why AT&T was rebuked by an advertising industry self-regulatory board in August for claiming that it already offered cellular coverage from space.
AST SpaceMobile launched its first five commercial satellites in September 2024. In late January, AST SpaceMobile said it obtained FCC approval to test the service “with unmodified smartphones in AT&T and Verizon premium low-band wireless spectrum supporting voice, full data, and video applications.” The company also announced plans to launch up to 60 more satellites in 2025 and 2026.
