Major U.S. network operators are slowly phasing out their 3G technology. In this post, I share my impressions about the status of the Big Four 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.
I’m not sure it’s correct, but I’ve seen an indication that AT&T plans to cease activating 3G-only devices on June 30, 2019.
As far as I know, T-Mobile hasn’t made any announcements about when its 3G network will be retired. I haven’t seen any information about intentions to block 3G device activation.
A document published by Multi-Tech indicates that Sprint may sunset its 3G network on 12/31/2022. I don’t know what source Multi-Tech relies on for that date.
Sprint appears to have had an intention to stop activating 3G-only devices on 4/30/2019. I haven’t confirmed that activations actually ceased.
