T-Mobile Starlink partnership: what the SpaceX snub means for you

T-Mobile rejected an MVNO deal with SpaceX. MVNO stands for mobile virtual network operator, a company that rents capacity on someone else’s towers and sells service under its own brand. Many budget phone brands are built this way. For SpaceX, it would have been a shortcut: sign up customers now, build its own network later.

Gopalan said T-Mobile’s test for any MVNO is simple. It has to bring in customers the carrier can’t reach alone, open new sales channels or add new abilities. A SpaceX deal fails all three, in his view, because T-Mobile already treats satellite as an add-on to its own network.

He also took a swipe at how fast SpaceX keeps changing its plans. Responding to a Barclays analyst, he said it is now hard to call SpaceX a satellite company at all, since it also wants to build towers on the ground. That is the real reason for the cold shoulder: SpaceX is no longer a partner with a complementary product. It is a would-be rival.

Yes. T-Mobile still works with Starlink through T-Satellite, and nothing announced this week changes that. T-Satellite lets T-Mobile phones connect to Starlink satellites in places with no cell signal. It works as a resale arrangement: T-Mobile buys the satellite service and sells it to you, so you stay a T-Mobile customer.

Gopalan drew that line clearly. He said he is very happy to look at resale deals for complementary products, the way T-Satellite works today, and that SpaceX could be a T-Mobile customer, or the other way around, under a normal commercial agreement. Renting out the network to a competitor is, in his words, a wholly different thing.

• Still on: T-Satellite texting and data in dead zones, sold by T-Mobile.
• Ruled out: SpaceX selling Starlink Mobile phone plans over T-Mobile towers.
• Possible: other resale or commercial deals between the two companies.

SpaceX has made its goal plain. In early October it agreed to buy nationwide 800 MHz spectrum licenses, radio frequencies that travel far and reach indoors well, and said the deal would pave the way for Starlink Mobile to become a major US carrier. It was also reported to be in talks to use about 80,000 US cell sites. Back in August, SpaceX chief operating officer Gwynne Shotwell said she expected to win quite a few customers from T-Mobile, Verizon and AT&T, promising to wipe out dead zones with satellites.

Now the shortcut looks shut at the two biggest carriers. Verizon CEO Dan Schulman said on his own earnings call that he sees no benefit at all in giving any satellite provider an MVNO deal. That leaves SpaceX with the slower, costlier path: own spectrum, rent tower space and build out coverage itself. The spectrum purchase still has to be cleared by the Federal Communications Commission, with completion pencilled in for the first half of 2027.

T-Mobile’s tech chief, John Saw, has argued the gap is huge. He wrote earlier this month that US carriers have invested more than $250 billion in network infrastructure since 2018, on top of over $200 billion in spectrum auctions over the past decade. Even after its new deal, he said, Starlink Mobile would hold roughly 80 MHz of spectrum, against T-Mobile’s nearly 400 MHz of mid-band and low-band holdings.

For most people, nothing changes this month. Your plan, your phone and T-Satellite keep working. The longer-term picture is more interesting.

A new national carrier usually means price pressure. SpaceX has money to spend: it is valued at about $1.914 trillion, against T-Mobile’s roughly $158.84 billion. If it builds its own network, it could undercut the big three in rural areas, where satellites help most. On the other hand, without wholesale access, any Starlink phone plan will take longer to arrive and may cover less at first.

Don’t expect satellite to replace home broadband in cities, either. Gopalan called satellite an inferior version of fixed wireless home internet outside deep rural areas, because everyone under one satellite beam shares its capacity. About two-thirds of T-Mobile’s home internet customers live in dense urban areas, where that limit bites hardest.

Meanwhile, T-Mobile is betting its customers will keep paying more. Average revenue per account rose 4% to $155.73 in the quarter, and the company raised its growth target for that figure. Postpaid account churn, the share of customers leaving each month, edged up to 1.09%, a small sign that rate-plan changes are pushing some people to look around.

T-Mobile used the same call to stake a claim on the next network generation. Chief technology officer John Saw said T-Mobile will be the first US carrier with 6G, pointing to an industry timeline around 2030. He described 6G radios that can also act like radar, sensing the world around them, and said traffic from AI wearables, robots and delivery drones will grow fast by then.

That is the deeper reason T-Mobile wants to keep its towers to itself. Both companies see the same future of connected machines, and neither wants to hand the other the keys.
