O2, the UK-based mobile operator has today announced that they are now offering 4G and Wi-Fi calling, allowing any o2 customer with a compatible phone (an iPhone 7 or iPhone 7 Plus) to make and receive calls over Wi-Fi or 4G.

This will allow you to get clearer call quality when you have a 4G signal, or just still make and receive calls when you have little to no signal over WiFi.

And all of this comes without using your data, instead, it will use your minutes.

Sadly, it is currently only available in London, Leeds, and Slough, however, O2 is planning to add more cities around the UK over the coming months.

If you live in one of those locations, here are the steps to get started:
