that would probably do it
i`d advise buying a goodybag next time.airtime credit can cost a fortune
you go here
https://giffgaff.com/goodybags and choose one
select i only need a goodybag
select the airtime balance box and click exchange airtime credit
you should now have an active goodybag which will last for 1 month
A £20 top-up isn't going to last very long watching video!
You'll be needing a giffgaff goodybag for better value.
They last a month,
then you could choose a different one,
depending on your usage.
