If you have O2 insurance it will show as a bolt on in your MyO2 and you will paying a monthly price for it. Some tariffs also came with a free screen replacement, but again, it will be a bolt on. If you do have O2 insurance, you should contact customer service to process the claim, if not, I would recommend going to Apple directly.

I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
