Add on

How do you buy a add on with credit. It only lets me choose bank or pay pal.

Do you mean “credit” as in credit card or pay as you go “credit” ? 

You can use a credit card to buy an add on if that’s your preferred payment method.

@DavidWa_2658972 If you have purchased an out of plan add on, this is effectively cash credit.

If you look at the Price Guide, you'll see that you can use it for international calls, to use data while roaming
outside the EU or to call premium rate numbers(084, 087)

Other types of add on you need to pay for with a standard method of payment.
