Major mobile network operators in the UK are constantly improving both their population coverage and landmass coverage, however there are still plenty of black spots where you just don’t get any reception at all.

Wi-Fi Calling is a technology which allows a smartphone user to make and receive calls over a wireless internet connection rather than a regular cellular connection. However, both your network operator and your handset should be compatible in order for you to benefit from this feature.
WiFi Calling lets you make or receive a phone call over an available WiFi connection. WiFi Calling works in areas with little or no cellular coverage.

Both your network operator and your handset should be compatible in order for you to benefit from this feature.
Nowadays almost all network operators offer Wi-Fi calling. However, some carriers may only provide WiFi Calling bundled with their premium plans. Others allow customers to enjoy it at no additional cost on all their tariffs, provided their phones support WiFi Calling. Keep in mind that, unless it’s stated otherwise by the network, this feature will only work in the UK.
When you use WiFi Calling, your network will charge you in the same way as normal, meaning usage will come out of your monthly allowance. If you’re on a pay as you go plan that supports WiFi Calling, you’ll be charged at the same rate as you usually would be for using your carrier.
