T-Mobile enlists Starlink satellites for new ‘SuperBroadband’ business internet service 

T-Mobile is boosting its footprint as a business internet provider, expanding further beyond its core offerings as wireless carrier, and it’s enlisting Elon Musk’s Starlink satellites to help.

The Bellevue, Wash.-based company on Tuesday unveiled SuperBroadband, a business internet service that combines T-Mobile’s 5G network with SpaceX’s Starlink satellite constellation to provide two independent connectivity pathways. T-Mobile says the service reaches every ZIP code in the country and comes with a 99.99% uptime guarantee.

T-Mobile has been aggressively expanding beyond wireless into broadband, ending 2025 with 9.4 million broadband customers after adding 2 million during the year.

SuperBroadband takes that push further into the enterprise market, targeting businesses frustrated by the complexity and spotty reliability of traditional internet providers, echoing the “Un-carrier” playbook T-Mobile used to shake up wireless more than a decade ago. 

The move expands on a partnership that dates to 2022, when T-Mobile and SpaceX announced plans to use Starlink satellites to fill cellular dead zones. It started with satellite-to-phone text messaging and has since expanded to include data service on compatible smartphones. 

The service is available starting Tuesday, with plans starting at $250 per month on a three-year commitment. That includes unlimited 5G and Starlink data, enterprise-grade equipment, installation, and ongoing management.

The service uses outdoor 5G equipment and routers from Ericsson’s Cradlepoint unit to combine the two connections into a single managed system, with T-Mobile handling installation through a partner called Acuative. T-Mobile said it plans to expand its hardware options to include equipment from Inseego.

T-Mobile’s rivals are pursuing business connectivity differently: AT&T is betting heavily on fiber, planning to reach 40 million locations by the end of 2026. Verizon recently started offering business fixed wireless access on a dedicated 5G network slice. 

Starlink and T-Mobile are neighbors in the Seattle region. The SpaceX satellite internet service builds its satellites in nearby Redmond, a short drive from the wireless carrier’s headquarters.

T-Mobile reports its first-quarter earnings on Tuesday afternoon, with Wall Street analysts expecting earnings of $2.06 per share on approximately $23 billion in revenue.
