Hi there @melita1993
If you have reported your phone/Sim as lost to Giffgaff, you would need to active the replacement Sim giffgaff send you, then (once activation has been completed in full, can take up to 24 hours) you can request your PAC to leave giffgaff and take your number over to Vodafone. To obtain your PAC from Giffgaff, please dial 43431 from the phone that your Giffgaff SIM card is inserted in and follow the verbal instructions. Giffgaff also have a facility to request a PAC online if that is more convenient for you http://giffgaff.com/help/pac-code-request
You will be sent your Giffgaff PAC via a text within 2 hours between the hours of 8.00 am and 4.00 pm Monday to Friday.
BEFORE YOU LEAVE GIFFGAFF: Please take a look at your Giffgaff Payment Details and make sure that Recurring Goodybag and Auto Top-up features are switched OFF (disabled). This would prevent future automatic repurchases. Thank you.
Sorry to see you leave Giffgaff, but, I wish you all the very best with your move over to Vodafone.
