Wi-Fi Calling is a feature that allows you to make and receive calls using a Wi-Fi network instead of a mobile signal. It is particularly useful for staying connected in areas with poor indoor reception or mobile "blackspots".
How does Wi-Fi Calling work?
When you enable Wi-Fi Calling, your phone routes calls through your wireless internet connection rather than the mobile tower. Calls made using Wi-Fi Calling are treated exactly the same as standard mobile calls:
- They are deducted from your monthly minute allowance.
- If you have used all your allowance, you will be charged at standard out-of-plan rates.
- Calls to premium numbers or international numbers are charged at standard rates.

Please note: You cannot use Wi-Fi Calling when you are abroad. It is available for domestic use within the UK only.
What is the difference between 4G Calling and Wi-Fi Calling?
- 4G Calling (VoLTE): Uses the 4G mobile network to carry your voice data, offering clearer audio than 2G/3G. It requires a mobile signal.
- Wi-Fi Calling: Uses a Wi-Fi internet connection. It does not require a mobile signal, making it ideal for basements or thick-walled buildings.

I am using Wi-Fi Calling but the call quality is still bad?
If your Wi-Fi calls are dropping or sound robotic, it is usually due to the quality of your internet connection rather than the phone network. Common causes:
- Weak Wi-Fi signal: If you move to a room with a "dead spot" or weak signal, the call may drop if there is no 4G signal to fall back on. Try moving closer to your router.
- Bandwidth usage: If others on your network are streaming 4K video or downloading large files, it may affect call quality.
- Third-party apps: Calls made via WhatsApp, Messenger, or Skype use different technology. For the best stability, use the standard Phone dialler app on your device.
Is it safe to use Wi-Fi Calling?
Yes. Wi-Fi Calling on modern Android and iOS devices is secure. Your voice data is encrypted, ensuring that your calls remain private even when connected to public Wi-Fi networks.
