When are carriers shutting down 3G?

While carriers have been planning the closure of 3G since 4G LTE took the reins (and the prospect of 5G being another catalyst) the agenda took a pause during the pandemic. Over the past two years, 3G-reliant services like home security systems and tech for the elderly have become more essential than ever, keeping telecommunications companies from pulling the plug. That is, until 2022, with major US carriers finally giving in and setting new shutdown dates that span across the year.

AT&T is the first of the big three, closing its 3G network on February 22, 2022.

T-Mobile has pushed its 3G shutdown to July 1, 2022, after initially planning for an October closing in 2021.

Sprint, now merged with T-Mobile, will close its 3G network on May 31, 2022.

Verizon's 3G network will shut off on December 31, 2022. The carrier has made it clear that "the date will not be extended again."

You can find more information regarding when the 3G networks close on FCC's website.
