Stay connected with O2

We’re investing in our network with the focus on each and every customer’s individual network experience. 

Our mobile network

We’re proud of our network. We’re the only UK network to make a 4G UK population coverage commitment to Ofcom and keep it. And we’re investing in the future, paving the way for 5G.

Wifi and 4G Calling

Make and receive calls with Wifi Calling even if you can’t connect to our mobile network. Get clearer calls and better indoor coverage with 4G Calling. Both at no extra charge.

Boostbox

Don’t let signal strength or a busy network hold you back. Boostbox is a small, low-powered cell that plugs into your broadband, giving you your very own voice and data hotspot.
