T-Mobile has announced that it is delaying its planned CDMA/3G service sunset. T-Mobile had previously planned to end its 3G service on December 31, 2021, but has now delayed ending its 3G service by three months, to March 31, 2022. T-Mobile states that its partners are lagging behind in transitioning away from 3G, and is thus providing the additional three months’ to allow its partners to transition.
