Is this in one place or many?
Have you checked status.o2.co.uk ?

Ok - It may be worth checking out the SIM. Clean the contacts with a pencil eraser (O2 will tell you to do that anyway). If you can try the SIM in another phone that would be great.
If problems persist you can try a replacement SIM from any O2 store.
