The withdrawal of the 3G network will start July 31, 2025, for Fizz and several of its partners. All calls made with your Fizz mobile plan will then go through the LTE network thanks to VoLTE technology. But to do so, you need to: Use a VoLTE-compatible SIM card or an eSIM (if your phone allows it). Use a phone that is VoLTE-compatible at Fizz. Activate the VoLTE function on your phone. IMPORTANT: If any of these criteria is not met, none of your c alls (including 911 calls) will go through when the 3G network is gone. To learn more about the withdrawal of the 3G network in Canada, visit the Canadian Radio-television and Telecommunications Commission (CRTC) website, and the Canadian Telecommunications Association website. What is VoLTE VoLTE stands for Voice over LTE, which basically means a phone call will use the LTE network. The opportunity to use the LTE network for your calls means: Improved sound quality for your calls. Faster routing of your calls, meaning the delay for the phone to ring at the other end will be shorter. Reduced interruptions when you go from the Fizz network to a partner network.

If it’s not VoLTE (voice over LTE) compatible, no calls (including 911 calls) will be possible with the plan associated with this SIM card when the 3G network is gone.
