I just bought a 20£ giffgaff goody bag and I just want to have this 20GB internet data which slows after reaching the limit.
But now I see that 4 days ago they changed the price to 25£. I'm not from UK, I'm just staying here for 2 months and I would like to know exactly what I have to do to have this package on my phone. Do I have to order a SIM card? Explain it to me please.
As you correctly state, the goodybags changed a few days ago.
If you bought your £20 goodybag before 11 July, it has 9GB of data then slows down between 08:00 and 23:59 daily.
If you bought your £20 goodybag on or after 11 July, it has 20GB fixed data allowance.
If you want the one with 20GB then slowed down data, it will cost you £25.00 but you cannot change the goodybag you've already got, so you wil lhave to wait until your next goodybag starts. Go here to select the one you want next https://giffgaff.com/profile/payment-details#goodybagsettings
Important: If you do not change the selected goodybag before 19:30 on the night your current goodybag expires, it will renew as the £20/20GB fixed data.
Ok I think I understand everything now.
So after I buy the 25£ goody bag I have to order the giffgaff SIM card? I can't use it on my old SIM card?
You do not need a new SIM, simply select the goodybag you want to use next and it will start as your current one expires. You can change to a different goodybag every time you buy a new one, should you wish to.
