Enabling O2 Wi-Fi Calling on Google Pixel
Not all O2 plans include Wi-Fi Calling. Log into the O2 app and check your plan features. Contact 202 (free from O2) to enable it if it is not included.
Wi-Fi Calling requires device support. On Google Pixel: go to Settings → Network & internet → SIMs → Wi-Fi calling and check if the option appears. If missing entirely, your device may not support this feature with O2.
Go to Settings → Network & internet → SIMs → Wi-Fi calling and switch the Wi-Fi Calling toggle on. On some Google Pixel models, this option only appears when connected to Wi-Fi.
Wi-Fi Calling settings may be hidden when not on Wi-Fi. Connect your Google Pixel to a Wi-Fi network, then navigate to Settings → Network & internet → SIMs → Wi-Fi calling to access the option.
On iPhone: Settings → General → About. If a carrier update prompt appears, tap Update. Carrier updates often add Wi-Fi Calling support for O2.
After enabling Wi-Fi Calling, restart your Google Pixel. Allow 2 minutes for O2 to register the feature. You should see 'Wi-Fi' or 'VoWiFi' next to the signal indicator.
If the Wi-Fi Calling toggle is greyed out and your device supports it, call 202 (free from O2). O2 may need to enable Wi-Fi Calling on your specific SIM or account.
