Don't see your phone make and model on the list? That means it'll no longer work by February 2022. So, you'll need to upgrade to a new one.

Devices no longer supported

We no longer activate phones that don't support HD Voice since they won't be compatible to work on our network when 3G shuts down.

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.
