I see from posts on this forum that if I sign up for a giffgaff goody bag that it doesn't allow the use of shortcodes.
I understand from these posts that you need airtime credits to be able to use short codes.
So, a few questions:
a) are airtime credits something you can add to a goodybag plan, or are they a diifferent plan?
b) assuming I can, how do I add airtime credits to a goodybag plan?

- by an app?
- online ?
