A Norfolk village has been without mobile signal for nearly a week.

Customers using the O2 mobile phone network in Caister, near Great Yarmouth, have been unable to make calls, send or receive texts or surf the internet during the outage.

A spokesman for O2 said: 'We've been carrying out some essential upgrade and maintenance works to masts that cover the Caister area. We apologise if this caused any inconvenience.

'This work is now complete and means our customers will have a greater experience when using our services such as mobile data on our 4G network.'
