Vodafone and O2 mobile phone customers in pars of the Isle of Wight are reporting a loss of signal this morning (Wednesday).
Essential maintenance is being blamed for the problems in areas, including Newport.

“We’re carrying out some upgrade work to help improve our network.
“While we do this, you might have some trouble with your calls, texts and data.
“We’re working as fast as we can.
“Everything should be back to normal by 6pm on Thursday July 18.”
Vodafone also says it hopes to have the affected areas restored by tomorrow (Thursday).
