Hi Biglittlebear.
The APN settings would be PPBUNDLE.INTERNET with our new PAYG modems.
You cannot top up online with a voucher, this would need to be done in store, or over the phone to our customer services department.
You can however register for an
online account and register a debit/credit card, and top up that way.
All the best
