my iphone 5 is showing the network and 3G logos but has no signal bars and I cannot make or receive calls or use the internet
Hi,
I recently bought my iPhone5 second hand off a friend. Having inserted my sim the O2 network logo and 3G symbols appear in the top left although there is no signal registered. I am also unable to make or receive calls as well as use the mobile internet.
The phone is registered to O2 so there is no network clash
THanks
iPhone 5, iOS 7.0.4
