Anyone else having this problem? My mate is on o2 and cant get a signal at all. Thought it was just his phone but when I looked at mine I'm having issues too (albeit on giffgaff, (same carrier)).

Yeah my signal has gone to - on tesco (o2) and in leasowe

Same here,network unavailable, I'm in New Brighton.

my parners is showing no service in ellesmere port

There is an issue with O2

Yeah my friend sent me a message using her wifi this morning to say she'd had no coverage for an hour. That was this morning and she said she's still having issues. That's in meols

Mine is OK, Moreton area.

It was off in Warrington and Midlands

Check the status here site slow so maybe there is a problem http://status.o2.co.uk/

my signal has gone, im in rock ferry, just been on line they said about compo but noy counting on it

turns out that the problem is nationwide

even cases where one o2 customer is having problems, yet the person next to you might have a fully working o2 signal

Apperently only certain handsets/numbers are being affected.

well I have O2 phone and also home phone and broadband from O2 and haven't had a single problem all day, and I'm in central Wallasey! (hope I don't tempt fate now I've said that! lol) :-)

2 o2 phones. 1 ok 1 no signal.

Not sure if it's related but my voda phone mobile was off all day yesturday.

It's just been on news at ten.
It's not just local to us it's a national problem in there core network.

It's as said above random and is changing all the time. The problem has been troubling o2 all day. They are still working to fix the problem so I would check in the morning, as I will.
