T-Mobile, Comcast, Charter Team Up on Mobile Services for Businesses

By Katherine Hamilton

Three leaders of the telecommunications industry are collaborating to bulk up their services for business customers.

Comcast and Charter Communications have agreed to use T-Mobile's network to deliver mobile services to their business clients starting in 2026, the companies said Tuesday. Financial terms of the multi-year agreement weren't disclosed.

The deal is expected to expand Charter's and Comcast's ability to deliver wireline and wireless offerings. Mobile services will be offered by Charter under its Spectrum Mobile for Business and by Comcast under its Business Mobile brands.

The program complements T-Mobile's existing offerings for business clients and expands its network to more customers, T-Mobile's chief product and digital officer Omar Tazi said.

Comcast and Charter together have more than 18 million residential and business mobile lines since they introduced their services in 2017 and 2018, respectively.
