SpaceX Cellular Starlink Tech Can Beam Emergency Alerts to All Users

Cellular Starlink can 'provide Wireless Emergency Alerts to everyone, including non-T-Mobile customers,' SpaceX says. But first, it must face the FCC and opposition from rivals.

SpaceX says its Starlink tech for phones will be able to send emergency alerts to all wireless users in cellular dead zones—even if they haven’t signed up for the satellite-based service. 

The company mentioned the potential feature in a Friday letter to the FCC, which will decide whether or not to give SpaceX regulatory approval for a commercial launch of its cellular Starlink tech.

The letter notes that SpaceX and its partner, T-Mobile, have been working to develop and launch the cellular Starlink system amid “enthusiastic support and eager anticipation from T-Mobile subscribers, including First Responders.”

The technology will harness orbiting satellites to beam data to phones on the ground, providing a way for consumers in dead zones to receive a cell signal. SpaceX has already launched over 130 “direct-to-cell” satellites in orbit, which have been able to send radio signals to unmodified iPhone and Samsung phones. 

In Friday’s letter, SpaceX added: “The two companies are especially excited about the service’s capability to provide Wireless Emergency Alerts to everyone, including non-T-Mobile customers, in areas where there is no terrestrial coverage.”

In other words, the cellular Starlink tech promises to benefit all consumers in emergency situations — but only if SpaceX gets regulatory approval from the FCC. SpaceX also requests “swift authorization” of its licenses to commercially operate the cellular Starlink tech. 

SpaceX's plan is facing pushback from rival companies, including AT&T and Verizon, which argue the cellular Starlink tech risks creating radio interference. Earlier this month, the carriers urged the FCC to deny SpaceX a waiver to operate the cellular Starlink satellites beyond the normal radio frequency parameters. In response, SpaceX told the FCC that many users won't be able to access its cellular Starlink system if AT&T and Verizon get their way.

The growing feud occurs as AT&T and Verizon plan on tapping a rival satellite company called AST SpaceMobile, which is planning on launching its own satellite internet service for mobile phones with a beta test, possibly as soon as December.

In the meantime, T-Mobile is aiming to launch the Starlink tech for its own customers this fall, first to enable satellite-based text messaging, before rolling out support voice and internet data in 2025. The carrier previously said it'll offer the Starlink satellite support for free for subscribers on its most popular plans.

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.
