Is this a new sim or one that hasn't been used for a long time?

I managed to do the first top up of a sim card last week through the My O2 app.
If you can't do that then you need to get a voucher
But if it isn't allowing you to even call 4444 then there is a problem either with the phone or with the sim card.
