Activating VoLTE & VoWiFi gives you a better experience with clearer HD calls, faster connections, the ability to browse while on a call and better coverage in tricky spots like underground.

Follow the steps below to activate your VoLTE & VoWiFi settings on your device.

Step 1: Enable VoLTE

Just note that if your iPhone is running iOS 26, VoLTE is enabled automatically by default, so you may not need to follow these steps.

Open Settings.
Tap Mobile Service (or Cellular, depending on your iOS version).
Tap Mobile Data Options.
Tap Voice & Data, then select 4G or 5G with VoLTE ON.

(If you are using Dual SIM, make sure you select the correct line first.)

Step 2: Enable VoWIFI

First make sure that VoLTE is enabled, as VoWiFi will not work without it. If you are in doubt, please see above. Once VoLTE is activated:

Open Settings.
Tap Mobile Service (or Cellular).
Tap Wi-Fi Calling.
Turn ON Wi-Fi Calling on This iPhone and confirm if prompted.
