First off, have you done a factory reset after updating to KK? We normally recommend this after a software update to stop conflicts with the old software. A useful guide Here
check your postcode here : O2 Service Status
Other things to try are cleaning the simcard or replacing it at the O2 store, they will arrange it for you but it can take up to 24 hours.
