Starlink and T-Mobile have opened their Direct to Cell beta test to select iPhone models. This test allows customers to connect to satellites when out of range of cellular towers. The beta test began in early January and initially started on several Samsung Galaxy phones. It is free to join, and T-Mobile is still accepting sign-ups.
A group of iPhone users shared a text message on social media informing them they were in the beta. According to the message and T-Mobile’s support page, you must update your iPhone to iOS 18.3 to use Direct to Cell. Currently, the service only supports text messaging and location sharing, but it plans to allow voice and data soon.
T-Mobile did not include a list of compatible iPhones but has stated that once the service fully launches, it will work with most modern phones.
iPhone 14 users and above have had limited satellite capability through Apple’s Emergency SOS service. This service connects to Globalstar satellites and allows users to contact emergency services outside cellular range.
Starlink Direct to Cell will connect to specialized low-earth orbit satellites, similar to cellular towers in space. Starlink and T-Mobile will need more satellites to offer voice, data, and IoT capabilities through Direct to Cell. Starlink aims to have voice and data ready for testing by the end of 2025.
T-Mobile has not announced final pricing for Direct to Cell service. However, Mike Sievert, CEO of T-Mobile, has alluded to the service being included in specific mobile plans.
How to Use Starlink Direct to Cell
If you’ve received the text message indicating that you’re in the beta, you won’t need to take any other actions to start using it. However, it will only work if you’re in an area that doesn’t have local or roaming cell service. Manually toggling on satellite connectivity doesn’t work, so you must venture away from cell coverage to try it out.
“T-Mobile Starlink currently supports sending and receiving text messages, location sharing, and texting 911 emergency services while connected to Starlink's satellites,” according to T-Mobile.
You’ll know you’re connected to Direct to Cell when your device displays “T-Mobile SpaceX” on the top left side of your screen.
Text messages sent via Direct to Cell may take longer than usual to send. You also won’t be able to send images or videos through text messages.
Customers in emergencies can also use the service to text 911 for assistance. The service will automatically share your location with first responders so they can quickly locate you. You can also share your location with other recipients using the Message app. Select “Apps” and “Location” to send the recipient your location information.
