It’s the beginning of the end for 3G cellular networks in the United States. The wireless standard was the first to deliver high-speed data over the airwaves when it first rolled out two decades ago, but since then it’s been largely supplanted by faster 4G networks and, more recently, 5G which can theoretically deliver higher speeds and reduce congestion.

Now US wireless networks are beginning to take their 3G equipment offline. AT&T is kicking things off by shutting down its nation-wide 3G network this week, but T-Mobile and Verizon will also shut off their 3G networks by the end of the year.


Here’s when each major US network is expected to shut off their 3G service:

  • AT&T: February 22, 2022
  • Sprint (owned by T-Mobile since 2020): March 31, 2022
  • T-Mobile: July 1, 2022
  • Verizon: December 31, 2022

MVNO (Mobile Virtual Network Operators) such as Straight Talk, Tracfone, Cricket, Boost, and Google Fi make use of the networks listed above, so their schedules will likely track with the major carriers.

For the most part, if you’ve purchased a new smartphone in the past decade, you probably don’t need to do anything, as it will likely support 4G or newer networks. And given that phones aren’t really designed to last, odds are that there aren’t a lot of folks still using old 3G-only models on a regular basis anymore.

But the shutdown could have more serious implications for 3G-enabled gear that typically has a longer lifespan. For example, the Associated Press reports that makers of home security alarm systems has asked the FCC to delay AT&T’s shutdown, as some security systems still rely on 3G networks to communicate with remote networks even if someone has cut the power and/or phone line to your home.

That said, the impending shutdown has been a long time coming… and a long time delayed. Verizon had originally planned to decommission its 3G network in 2020, but chose to push that date back by more than two years.

  1. Bah. Was still using my ancient 4G/LTE Xperia ZL, which otherwise still works perfectly fine – but doesn’t support VoLTE, so it’s e-trash today (as is my more ancient 3G N900).

    Don’t give af about “faster” mobile data, since faster technology has only led to much poorer reception, at least in rural America. Imo, they should’ve kept 2G around forever for legacy phone calls and texts.

    At least my 4G/VoLTE PH-1 is supposedly supported after an undefined “update” according to the AT&T whitelist. Lol, f’ing greedy, corrupt and incompetent telecom industry just wants to sell new phones.

  2. The Amazon Kindle (3) Keyboard is affected. Any ideas about what sort of alternative services support this device?

    1. I believe the only way to load books moving forward will likely be via the micro USB port. You should be able to connect it to a PC and load ebooks manually or using software like Calibre.

    2. I have the Kindle 3G (keyboard), it still has Wifi.

      If you’re asking if there are any providers out there that can support its 3G connection, the answer is no. It was an exclusive arrangement with specific 3G providers in each country, there was never an opportunity to connect it to another network.

    3. I have the same Kindle (Kindle 3G/Kindle Keyboard), and it is possible to swap the Sim card inside it with one from another provider. It requires a bit of modification to the software though.

      Having said that, you’d need to find a provider that offers 3G service that supports the bands the Kindle uses. Seems like a wasted effort to me.
