Making the switch from Boost mobile

Why would T-Mobile allow you to keep your Boost Mobile plan? Virgin Wireless was bought out by Sprint in 2009 and they did offer extremely tweakable "custom" service plans. Boost Mobile was a also a subsidiary of the Sprint Corporation but in July 2020 Boost mobile became owned and operated by Dish Network. T-Mobile did, in April of 2020, become the new owners of Boost Mobile but the merger between Sprint and T-Mobile was slowed by the United States Department of Justice, after it raised concerns over a lack of competition in the telecommunications industry. Eventually, Dish entered the talks and agreed to purchase Sprint assets, including its prepaid business. As for current promotions on T-Mobile though, you can find all the information aquí.
