BBC News - Vodafone network hit by break-in
Vodafone's mobile network has been disrupted following a break-in at one of its exchange centres.
The company said some customers had lost voice, text and internet access.
Engineers are working to fix the problem, according to a Vodafone statement.
It is not known how many users have been affected, however mobile customers from across the UK were using the micro-blogging site Twitter to report loss of service.
Vodafone said: "We had a break in last night at one of our technical facilities which resulted in damage done to some of our equipment.
"We are working quickly to restore these and will be back to normal as soon as we can."
