T-Mobile coverage expands in downtown tunnels
T-Mobile coverage has expanded in MBTA’s downtown tunnel system. The service is now available on 13 of the approximately 20 miles of the T system that are underground, officials said. The MBTA, which has more than 795,000 riders each weekday, has a long-term contract with InSite Wireless to distribute wireless service in subways. Any carrier can use the InSite Wireless signal to reach its customers. With its latest expansion, T-Mobile provides the most coverage for its customers when they are riding underground, officials said. InSite is continuing to talk with Verizon and AT&T about expanding their coverage in the tunnels. AT&T is expected to expand its coverage later this year, the MBTA said.
