Major U.S. network operators are phasing out their 3G technologies. Below, I share my impressions about the status of the major networks’ 3G phase-outs. It’s possible some network operators won’t stick to their deadlines (plenty of early deadlines have already been pushed back).
Verizon has twice set and then pushed back deadlines for retiring its 3G network. The date is now set at December 31, 2022. Verizon committed to not push the deadline back any further.
Verizon has stopped activating 3G-only phones and phones that don’t support HD Voice. More details about Verizon’s plans and policies can be found in an entry on Verizon’s knowledgebase.
AT&T plans to retire its 3G network by February 2022.
T-Mobile has mostly stopped activating 3G-only phones. The company plans to shut down its 3G network as of July 1, 2022.
T-Mobile plans to shut down the legacy Sprint 3G/CDMA network it acquired by March 31, 2022.
