Data cut off early

[Jami]

I should have 4 days left on this month of my sim and my data and plan has cut off early. I was planning on getting a pay monthly sim after this and I can’t get the good deals because now my number isn’t valid. Why has it cut off four days early? It even says that I still have so much talk text and data left but won’t actually let me use it

We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. If you message O2 using the links below, they should be able to help you with this

Could be a sim, phone or network issue.
