A message prompts up there
You need to active your sim or you must be logged in.
While i am already logged in
Have you actually used your sim within the last 6 months?
You need to have made a call, send a text or use some data to keep it active.
I see you have only been with giffgaff a few weeks.
What payback exactly do you think you were due?
And did you choose a payout option, and if so what option did you choose?
If you need further help please answer those questions and confirm you have a working giffgaff sim that you are using, EG you have actually called and text people using your giffgaff sim card.
