T-Mobile and SpaceX’s Starlink are partnering to eliminate mobile dead zones by delivering satellite connectivity directly to standard smartphones, with no extra hardware required.
The service uses specially configured satellites orbiting more than 200 miles above Earth at speeds exceeding 17,000 miles per hour to send cellular signals to areas where conventional towers cannot reach.
At launch, T-Mobile Starlink will support text messaging, group texts, and message reactions. The partners intend to expand capabilities to include picture messaging, voice calls, and mobile data. When a phone loses connection to a terrestrial cell tower, it will automatically switch to Starlink’s satellites so communication continues seamlessly; messages will be sent and received just as they are on a regular cellular network.
T-Mobile CEO Mike Sievert described the collaboration as a major advance in wireless connectivity. “T-Mobile Starlink is the first and only space-based mobile network in the US that automatically connects to your phone, so you can stay connected even where no cellular network reaches,” he said. “We’re still in the early days, but we’re officially putting ‘no bars’ on notice. Dead zones, your days are numbered.”
Connectivity — anywhere with a clear view of the sky
The T-Mobile Starlink service is designed to work on most smartphones released in the past four years, eliminating the need for special equipment or additional hardware. T-Mobile will publish a list of supported devices; initial compatibility includes models with minimum specifications similar to the iPhone 14, Samsung Galaxy S21, and select Google Pixel phones. More models will be added over time.
In addition to standard messaging, the network will support Wireless Emergency Alerts (WEAs), ensuring that people in remote locations or disaster-affected areas can receive critical notifications from a T-Mobile Starlink satellite even when they are outside traditional cellular coverage.
Beta testing begins — free access until July
T-Mobile has started enrolling users in a beta program ahead of the official July launch. The company initially invited a small group of T-Mobile customers with newer devices to participate, but the beta is now open to everyone, including subscribers of other carriers such as AT&T and Verizon. Participants will be added gradually as T-Mobile refines the service before full rollout.
After launch, expected pricing is:
- T-Mobile Go5G Next and Go5G Business Next customers: included at no additional cost
- T-Mobile customers on other plans: $15 per month per line
- AT&T and Verizon customers: $20 per month per line
For early adopters, T-Mobile is offering a promotional rate during February of $10 per month per line, a 33% discount off the regular T-Mobile rate.
AT&T and Verizon customers can join the beta
Customers on AT&T and Verizon can join the beta program using their existing smartphones and can send satellite text messages for free during testing. After the full launch in July, they may continue with the service at the $20-per-month-per-line rate. No additional hardware is required — only a compatible, unlocked smartphone that supports eSIMs.
Building a global satellite network
While the initial offering targets US customers, T-Mobile and Starlink are inviting global carriers to join the satellite-to-mobile alliance. Several international operators have already partnered, including KDDI (Japan), Telstra and Optus (Australia), One NZ (New Zealand), Rogers (Canada), Salt (Switzerland), Entel (Chile and Peru), and Kyivstar (Ukraine).
Expanding the future of space-based connectivity
Currently, T-Mobile Starlink connectivity is limited to SMS messaging, but planned upgrades will add voice calling and mobile data capabilities, effectively transforming compatible smartphones into satellite-enabled devices.
The beta program is open now for eligible users.
