Dish Network is not happy with T-Mobile over its plans to shut down a network still used by millions of Dishs Boost Mobile customers. In a letter to the FCC on Thursday, Dish blasted the Bellevue, Wash.-based wireless carrier for what it called anti-competitive behavior.
Axios first reported on the spat.
Dish acquired Boost as part of the merger between T-Mobile and Sprint, which was completed a year ago. T-Mobile sold Sprints Boost prepaid business to Dish as a concession to win federal approval for the deal.
Dish is relying on T-Mobiles legacy CDMA network technology as it works to build out its own 5G network. But it will reportedly take several years to replace the old service and transition the majority of Boosts 9 million customers.
Axios reported thatDish was expecting T-Mobile to shut down the CDMA network in three to five years, but that date is now looking more like Jan. 1, 2022.
During its earlier life as the Un-Carrier, T-Mobile championed policies that promoted competition, diverse spectrum ownership, and efficient spectrum use. How quickly things change, Dish said in its letter. Now, T- Mobile opposes measures that would help new entrants and smaller providers compete .
The letter notes that Verizon, with just 1% of customers still on the legacy tech, isnt looking to wind down its CDMA service until 2023.
T-Mobiles filing is just its latest attempt to flex its power to thwart competition, Dishs letter added.
