Firstly, Ensure that you do actually have an active goodybag or airtime credit available on your account.
From your handset:
Dial *100*7# to check your goodybag allowanceDial *100# to check your remaining airtime credit balance
Check your dashboard page to ensure that your goodybag or airtime credit is still available and is showing on your account here:
(If your phone is auto SETUP to giffgaff when the sim is inserted, Ensure that you don't select the GIFFGAFF apn) When resetting your APN settings to 'default' as mentioned in '2' on the above given link, Ensure that you select the O2 Pay and go (APN) and then ADD the giffgaff APN settings manually
