T-Mobile US has confirmed that it will shut down its 3G network on 1 July 2022. The cellco’s official clarification comes a matter of weeks after internal employee documentation indicated that T-Mobile was on course to deactivate the platform in October 2021.
TeleGeography notes that the legacy Sprint networks acquired in the April 2020 mega-merger will be deactivated on 1 January 2022 (CDMA) and 30 June 2022 (LTE), respectively.
T-Mobile’s 2G GSM network is tentatively scheduled for shutdown on 31 December 2022, although this date is subject to change, with T-Mobile admitting: ‘We’ve also shared that we plan to retire T-Mobile’s older GSM 2G network … but no date has been set.’
