T-Mobile Posts 10.6% Revenue Rise While Funding $2.7B Fiber Push and Starlink Broadband

Context The earnings release followed weeks of speculation about a possible merger with parent Deutsche Telekom, which the CEO declined to comment on but acknowledged internal governance reviews. Despite the rumors, the carrier highlighted strong operational performance, adding 217,000 net post‑paid accounts for broadband and mobile and raising its full‑year subscriber outlook.

Key Facts Revenue reached $23.1 billion, reflecting a 10.6% YoY increase. T-Mobile said it will invest $2.7 billion in two new fiber joint ventures announced on April 28, aiming to reach 12‑15 million households by 2030. Its SuperBroadband service, launched with Starlink, starts at $250 per month and includes unlimited 5G data, backup Starlink data, enterprise equipment, and full management.

What It Means The revenue growth shows T-Mobile’s core wireless business remains resilient even as it diversifies into fixed‑line and satellite broadband. The fiber investment signals a long‑term push to capture suburban and rural markets, while the Starlink‑tied product targets business customers needing high‑availability connectivity. Investors will watch how quickly the fiber JVs scale and whether SuperBroadband gains traction in enterprise sectors.
