T-Mobile confirms it has leased spectrum to other carriers to expand LTE network coverage

T-Mobile US has leased its spectrum to other carriers in an effort to expand its LTE network. However, it's unclear how extensive those efforts have been or how T-Mobile's work with other carriers compares to similar programs from Verizon Wireless and Sprint. "We're always exploring opportunities to enhance America's fastest 4G LTE network," a T-Mobile spokesperson said. "Over the years, we've bought, sold and leased spectrum to roaming partners and we'll continue to discuss additional opportunities that will benefit our customers." T-Mobile declined to comment on how many carriers it has leased spectrum to, what spectrum bands were leased, or how much territory those leases cover. "T-Mobile is always looking for the right opportunities to improve its network," the spokesperson said in a statement. "This includes spectrum swaps, leasing spectrum and roaming agreements. We'll continue to discuss additional opportunities as they arise and make the best decision to benefit our customers."
