Hi @aitchgee
Calling 2345 from the Vodafone payg phone should work !
Here is the support pages about how you can also top up other ways > Pay-as-you-go/Topping-up/How-can-I-top-up-my-phone-or-another-number.
If I can be of any further help then please don't hesitate. Take care. 😎
Current Phone >
Samsung Galaxy s²³ Ultra 512gb Phantom Black.
