That sounds like a sim card failure, the best option if you want to be up and running before the new year is to pop down to an o2 store with Photo ID and get a new sim card there and then.
If you cant get to an o2 store then you will need to call customer services on 0344 809 0202 from another phone and get one posted to you.
This is not customer services and we dont have access to your account
I do not work for o2 or any VMo2 /Telefonica/Liberty Global Company
