Yesterday we reported that O2 customers in the UK were unable to access the network. The problem appeared to only affect a certain number of people, and was not related to geography either.

Hundreds of thousands of customers were affected by the technical issue.

The mobile phone network company have run final tests and confirmed that both 2G and 3G networks are now fully functional once again.

They managed to narrow down the issue to a network systems that deals with the registration of numbers. Full details are still unavailable with analysts suggesting O2 don’t actually know what caused the issue.

O2 feels that they may have missed maintenance in order to work harder on the release of a 4G network, forgetting that all of us are still on their 3G or 2G networks and therefore rely on it.
