Elon Musk: Cellular Starlink Will Only Be Exclusive on T-Mobile for the First Year

Elon Musk is signaling that 'direct to cell' Starlink capability for phones could go beyond T-Mobile to other carriers, such as AT&T and Verizon, assuming they want it.

T-Mobile might not be the only US carrier partnering with SpaceX on cellular Starlink service.

Over the weekend, CEO Elon Musk said SpaceX has an exclusivity agreement with T-Mobile on delivering cellular Starlink connectivity. But apparently, the deal won’t last long. 

“Starlink direct to mobile phone Internet is exclusively with T-Mobile in the US for the first year, then other carriers thereafter,” Musk tweeted. “We are starting off working with one carrier in each country, but ultimately hope to serve all carriers.”

The tweet raises the possibility that SpaceX could expand cellular Starlink access to AT&T and Verizon — but only if the carriers partner with the company. So far, those two rival carriers are backing a rival startup in Texas called AST SpaceMobile, which is also preparing to use orbiting satellites to beam high-speed internet to phones on the ground. 

AST SpaceMobile is preparing to send up its first batch of commercial satellites this month with the aim of kicking off beta testing with AT&T and Verizon as soon as December. However, the startup needs to launch between 45 to 60 commercial satellites before it can offer continuous coverage in the US.

In contrast, SpaceX has already launched over 160 satellites for its cellular Starlink system, which plans to start serving T-Mobile customers later this fall, starting with text messaging before rolling out internet and voice connectivity in 2025. As a result, Musk's tweet suggests he'll try to attract business from AT&T and Verizon at the expense of AST SpaceMobile.

Musk's tweet also comes he’s been promoting the benefits of the cellular Starlink service to secure approval from the FCC, despite opposition from AT&T and Verizon. Last week, Musk mentioned that the cellular Starlink tech could offer free emergency service to any phone located in a cellular dead zone — even those belonging to other carriers. 

It’s also possible Musk’s tweet is more about the cellular Starlink service operating exclusively in the US for the first year before it expands to other markets, such as Australia, Canada, and New Zealand, where SpaceX already has deals with local carriers.

SpaceX and T-Mobile didn’t immediately respond to a request for comment.

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.
