Act now - 3G is gone

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

Devices that still work

Devices Working on ATT Network (PDF, 506KB). It’s important to check the device model numbers to make sure it’s still supported since 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.

Upgrade your AT&T Wireless device

Talk and data services will only work for AT&T Wireless^SM phones and devices that support at least 4G LTE and HD Voice. Here’s how you can replace your device:

• Upgrade your device online
  
• Make an appointment at one of our stores
  
• Swap to a different compatible device
  

Don’t want to replace your phone? Make sure you cancel any lines you don't use.

Upgrade your AT&T PREPAID device

Talk and data services will only work for AT&T PREPAID^SM wireless phones and devices that support at least 4G LTE and HD Voice. Here’s how to upgrade an AT&T PREPAID device:

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.

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

Moving your SIM to another device?

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

Have AT&T MicroCell?

If you used an AT&T Microcell, it won’t work on our current network. See if an AT&T Cell Booster can help
