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.” Recommended by Our Editors Starlink's $50-Per-Month 'Backup' Plan Has One Big Downside Elon Musk Using Cybertrucks As Starlink Stations for LA Fire Relief AST SpaceMobile's Large Satellites to Roll and Tilt to Prevent Astronomy Interference

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.
