1) you haven't paid the bill
2) the phone is blocked because of (1)
3) the phone is damaged
4) there is no signal in your area
#3 can easily be proved by trying in another unlocked/o2 phone. #4 will normally be realised by going elsewhere or other o2 customers are reporting the same thing. Also try cleaning and reseating the sim card.
The first 2 points can only be resolved by ringing CS.

I have a restriction put on so i can go no more than £10 over once my allowance has been used.
Will try putting my sim in another phone and see what happens
O2 don't put restrictions on accounts like this.
