UPDATE 2/9: T-Mobile has since expanded its beta to iPhones running iOS 18.3. And it just revealed in a Super Bowl ad that its cellular Starlink service will launch in July. It'll be free for those on its most expensive plan, but others will have to pay $15 per month. Plus, it'll be open to AT&T and Verizon customers—for a price. Get all the details here.

Original Story:
It looks like T-Mobile is now accepting customers into the free beta program for SpaceX’s cellular Starlink service—but only if you have the latest Samsung handsets. 

On Tuesday, a number of T-Mobile subscribers reported receiving access to T-Mobile's "direct-to-cell" Starlink beta program, which the company announced last month.

T-Mobile has been notifying eligible customers through text messages, according to social media posts. One included a screenshot showing a T-Mobile account subscribed to the satellite network. 

The technology lets you send text messages without relying on traditional ground-based cell towers. Instead, the phone relays the text messages using orbiting Starlink satellites, giving consumers a way to remain connected in cellular dead zones, similar to Apple’s Emergency SOS satellite messaging for iPhones. 

When we asked about the beta launch, T-Mobile said: "We continue to make great progress toward a full beta test availability; more details to come soon."

In the meantime, the carrier also published a new support document that reveals the cellular Starlink system only works on five Samsung models for now: the Galaxy Z Flip 6 5G, Galaxy Z Fold 6 5G, Galaxy S24 5G, Galaxy S24 Plus 5G, and Galaxy S24 Ultra 5G

“Text messages may take longer than normal to be sent while connected to the T-Mobile Starlink satellite network,” the support document says. “Picture and video messaging is not included during the beta phase.”

Eligible phones will only switch to satellite connectivity if customers are in an area without traditional cell or roaming services. “Manually selecting the T-Mobile Starlink network will not work while other cellular connection options are available,” the document adds. “When connected to T-Mobile Starlink, your device will display T-Mobile SpaceX at the top-left side of your screen.”

SpaceX recently secured approval from the FCC to operate the cellular Starlink technology commercially. T-Mobile has not announced pricing, but SpaceX plans to eventually support data and voice calls via the cellular Starlink service.

T-Mobile has also activated the cellular Starlink tech for customers living in areas of Los Angeles devastated by the recent wildfires. The same satellites will also beam emergency alerts to all phones in the affected areas, regardless of carrier.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
