New PAYG sim won’t top up

[SueP]

I am finding it impossible to top up my new Big Bundle PAYG sim either online or through the O2 app. I got one message saying it was not a PAYG number which is daft as I have just ordered it! Any help gratefully received as the phone is for my Dad to keep in touch during lockdown.

All ways to top up are here

I have tried all of those ways numerous times and none will work. Getting to the point where I’m about to give up on O2 altogether.

Sorry but there must be somethiing wrong with the system then which is no surprise to me.

Customer services are closed today but open again tomorrow at 10am

The first top up needs to be a voucher, as explained in the guide @SueP
