I wanted to unblock mobile data on SIM card so I done it through the app and that was 3 hours ago and it’s like it’s froze

This looks like something you’d need to call O2’s customer service team about – give them a call on 202

or 0344 809 0202 (or Payment management number -0800 902 0217 )

If you have no access to a phone then use Skype to call 0800 032 1402 Guide: A Guide to Skype
