This looks like something you’ll be able to do or check in the My O2 app. We have a guide to help with that if you’re unsure how to use it 

https://community.o2.co.uk/t5/How-to-Guides/How-to-guide-My-O2/ba-p/1275603

And don’t worry if you get stuck because there’s an in-app messaging service you can use to chat with O2 who can help. Just go to the ‘Support’ tab and ‘Start a Conversation’ at the bottom.
If you still need help then the Social Media teams will be on hand, just send them a message
