Dish's Boost Customers Need to Leave Legacy Network, T-Mobile Tells FCC

T-Mobile defended its plans to close its legacy CDMA network at the end of this year, against criticism from Dish Network (see 2104010044), which said doing so will harm Boost subscribers. “All CDMA customers, including DISH’s Boost-branded customers, will receive enormous benefits by migrating as planned onto T-Mobile’s new network, and it is absolutely in their best interest to do so,” said a letter to acting FCC Chairwoman Jessica Rosenworcel, posted Monday in docket 19-348. Under T-Mobile’s agreement to sell Boost to Dish, “it is unambiguously DISH’s financial responsibility to migrate customers to the new technology in a timely manner, and if they live up to those obligations, no consumers will be negatively affected by the sunset and in fact will receive substantial benefits,” the filing said: The move from CDMA to the new network will provide Dish's Boost-branded customers and T-Mobile’s CDMA customers “a far better experience than that on CDMA.” Dish didn't comment.
