You can use Wi-Fi Calling wherever you have a good Wi-Fi signal with a good internet connection. You’ll also need a compatible phone on a Red, or Red Value Bundle, Red+ or Business Premier.
You can also use Wi-Fi calling on the London Underground. Check our Wi-Fi Calling on the London Underground page for details.
If there’s no phone signal available, but you have a Wi-Fi network in range, any call to the emergency services will automatically use Wi-Fi Calling.
