Major U.S. network operators are phasing out their 3G technologies. In this post, I share my impressions about the status of the major networks’ 3G phase-outs. For what it’s worth, I’m not confident all of the information is correct, and it’s possible some network operators won’t stick to their current 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.
While 3G-only devices already on Verizon’s network continue to work, the carrier 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. I’m unsure when the 3G network will be shut down for users already accessing on it. I’ve seen a rumor suggesting the 3G network may be retired around April 2022.
