How our network works

Keeping you connected

Behind the scenes at the O2 machine

You're a busy lot. You send about 150 million texts a day and make more than 120 million calls.

Not to mention checking emails, sending files, social networking and uploading videos.

That keeps us pretty busy too. Our nation-wide engineers work 24/7 365, ready for action if there's any problem with the network. We check coverage constantly and always report any temporary glitches on our free My Network app. And if you'd like an up-to-the minute update on your local area, get all the info on

And at big live events like festivals, where signal can sometimes be an issue, we check how customers are getting on; boosting coverage if necessary, so they can really make the most out of the likes of TU Go, and our O2 Wifi hotspots.
