Have you tried the sim in another phone.
If the phone is sending a report then the phone sounds like it has an issue.
Have you tried backing up the phone and then doing a factory reset first. and seeing if that clears up the OS issue.
It might also be worth contacting o2 to request a new sim card, you can either pop into an o2 shop with Photo ID or call 0344 809 0202 from an other phone
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
