T-Mobile has launched its direct-to-device (D2D) satellite service, T-Satellite, across the US.

The service, which is supported by SpaceX's Starlink, is now commercially available for T-Mobile customers, plus AT&T and Verizon customers. (Update: Starlink is currently suffering from a global outage.)

The launch of the service comes after the carrier held a six-month beta trial of the service.

According to T-Mobile, close to two million people tried T-Satellite during the test period, with up to 30,000 daily T-Satellite users.

T-Mobile's D2D service allows customers to connect their smartphone automatically to a constellation of more than 650 LEO Starlink satellites.

The launch of the service builds on the partnership between T-Mobile and Elon Musk's SpaceX, which first announced plans to cover dead spots from space nearly three years ago.

In the company's announcement yesterday (July 23), T-Mobile said it expects to extend the service to locations outside of the US, though it didn't note where.

"This is an important step for public safety, but it’s just the beginning. In October, we’ll add app capabilities — think access to maps, weather information, trail guides, social media, and more," said T-Mobile.

The carrier also highlighted the impact of T-Satellite during a number of natural disasters, notably claiming that during Hurricanes Helene and Milton, one million people connected to the service, while 410,000 people connected amid the Los Angeles fires earlier this year.

T-Satellite is included for T-Mobile customers on the Experience Beyond & Go5G Next plans, while customers on other plans can sign up for $10 per month.

As for AT&T and Verizon users, it's available for $20 per month, but can be purchased for $10 per month for a limited period of time.

Those two telcos have been pushing their own satellite messaging services in partnership with AST SpaceMobile. Verizon also has a satellite messaging service with Skylo.

Record postpaid additions for Q2, UScellular acquisition will complete next week

On the same day that the company launched T-Satellite, the carrier also announced its second-quarter earnings for 2025.

T-Mobile reported service revenue had grown by six percent to $17.4 billion for the quarter.

During the quarter, the telco added more than 830,000 postpaid phone net customer additions, the highest in the company's highest. In contrast, Verizon said earlier this week that it has lost 9,000 connections during Q2. AT&T, meanwhile, added 401,000 net post-paid customers.

"T-Mobile crushed our own growth records with the best-ever total postpaid and postpaid phone nets in a Q2 in our history," said Mike Sievert, CEO of T-Mobile.

T-Mobile also reported 10 percent growth in net income for the quarter, hitting $3.2bn.

During the company's earnings call, Sievert added that the imminent acquisition of key UScellular assets will help the carrier "shore up" coverage in rural areas of the US.

"We're also shoring up our network in smaller markets and rural areas with UScellular," he said. "With all required approvals now in place, I'm pleased to say that we plan to close the transaction and become one team next week on August 1st."

The acquisition will enable T-Mobile to expand its site coverage from 9,000 to 12,000 sites, he added.

T-Mobile's acquisition of Metronet is expected to close even quicker, with the deal set to complete today (July 24). The move follows T-Mobile's acquisition of Lumos in April and heightens the carrier's fiber push.
