Topups do not buy goodybags, they buy PAYG credit and if you turn data off on your phone, no PAYG credit will be used. But for most people, goodybags are much better value than PAYG credit.
It's not possible to top up a goodybag at all -- you must buy a completely new goodybag, which will last a full month and will completely replace not add to the current goodybag.
All goodybags even the smallest come with some data. Despite that, goodybags are still almost always better value for most people.
Goodybags should always be bought either:
- at https://www.giffgaff.com/buy/goodybag (all payment methods supported here) or
- if paying by voucher dial 43430 and choose option 2 not option 1
- 43430 option 2 not option 1 can also be used to buy a goodybag from existing credit, but it is very strongly not recommended to add credit first if the intention is to use the credit to buy a goodybag.
