O2 network coverage disruption is advising customers to switch off data services on their phones to restore network.

O2 suffered a nationwide outage yesterday which is continuing into today. The cause of the service failure is apparently because some phone numbers not registering with the network.

The company's service has now been restored, allowing customers to use calling, texting and cut-speed web services (GPRS), but so far 3G network is still down.

The statement on O2's blog;

We would like to apologise for the service disruption some of our customers have been experiencing since yesterday afternoon.

At approximately 13:30 yesterday we experienced a fault with one of our network systems which meant that some numbers were unable to register correctly on our network. As a result, some customers have had difficulty making or receiving calls, sending texts or using data.

We, and our central supplier, have been working through the and this morning using all possible resources to restore service.

As at 0800 this morning, our 2G was restored. Customers who were affected should now be able to make and receive calls on the 2G network (they may find it helpful to turn their phone on and off once)

Our 3G service is starting to restore and customers should expect to see a gradual return of data services as the day progresses.

We will be updating regularly as the situation improves across our status checker, Twitter and this blog post.
