Sim
What phone do you have?
Try taking out the sim, clean and replace, then reboot the phone.
Re: Sim
If you can, try your SIM in another phone, if it works then, your phone is faulty, if not you'll need a new SIM which your local O2 shop can sort out for you for free .
If you don't have access to another phone, you can ask in your local O2 shop to test it for you too.
Hi @vnuala, I was wondering if you got the chance to try out any of the above suggestions? Any progress?
