Get details on the 3G network shut down

We phased out our 3G network, but don’t worry—we’re making room for an even better network.


DETAILED INFO

What to know about 3G going away

To bring you faster speeds and new features, we're excited to upgrade America’s best network.1  One change we made was to shut down our 3G network.

Devices that still work

Find out if your device still works on our network (PDF, 513KB). It’s important to check the device model number to make sure it’s still supported after the 3G network shutdown. This includes iPads®, tablets, and wearables.

Once you know your device still works, you may need to restart your device or check the VoLTE or LTE status. (See the FAQ for more details)

Don’t see your phone make and model on the list? That means it may not work anymore. You may need to swap or upgrade to a new one.

Get help upgrading your AT&T PREPAID device

To continue getting access to talk and data services, you’ll need to upgrade to a AT&T PREPAIDSM wireless device that supports at least 4G LTE and HD Voice. Here's how to get started:
  1. Visit one of our stores to get a new phone.
  2. Place your SIM card into the new phone. (If your SIM card doesn’t fit, get a new SIM card kit from our store.)
  3. Sign in to att.com/myprepaid.
  4. Select My Device, then Update Device.
  5. Follow the prompts to update your IMEI or SIM card number.
Have session-based pricing for a data-only device? Your data-only device will only work if it supports 4G LTE speeds and higher.

Devices no longer supported

We no longer activate phones that don't support HD Voice.

FYI: If you switch your SIM card between devices, make sure the device you're moving your SIM card to works on our network. Want to use your original device again? Make sure the SIM from the original device will work on our network.
