We’re building a faster, smarter, stronger network

We are currently undertaking an unprecedented network Modernisation programme across the UK. We’re investing £1.5million every day in rolling out our new 4G network and upgrading our current 2G and 3G networks. In fact, by the time we’re done in 2017, we’ve promised Ofcom that we’ll cover 98% of the UK population across all our networks (whether outdoor or indoor).

Keeping our customers connected is our priority and we always plan to do our upgrade or maintenance work as quickly and as impact-free as possible. Sometimes we might affect your signal unavoidably and if we do that we’re sorry.

To find out if we are working in your area, right now, use our network checker below.

We monitor this site 24/7 and use the data from your check to tell us if there are any problems that we’re not already fixing. It’s rare that we’re not already on it, but we like to be sure.
