Just 2 things to bring your mobile number to giffgaff:
1) PAC code: You'll need a PAC (Porting Authorisation Code) from your current service provider.Contact your current service provider and request a PAC code as you want to transfer (or 'port-out') your number to another network. PAC codes are valid for 30 days from the issue date
2) Active giffgaff SIM: You'll need to have an active giffgaff SIM so we can process the transfer (make sure your giffgaff account and SIM has been activated if you haven't already.
Typically it shouldn't take more than 2 days
Transfer your number
Hi, i have just brought a giffgaff sim card but do not get signal at home, i need the PAC code to move to another provider but it says access denied .. can anybody help?
You need to wait (up to 24 hours) for your SIM card to become fully activated before you can request a PAC
After this time, dial 43431 or go to http://giffgaff.com/help/pac-code-request to request a PAC (Porting Authorisation Code)
The PAC will be delivered by SMS within 2 hours (M-F 8-4) and displayed on your dashboard under your number.
The transfer must be initiated within 30 days of requesting the PAC, otherwise it will expire and you will need to request another. Please be aware that mobile networks are not obliged to provide a PAC once your account with them has been terminated.
You will permanently lose the credit/goodybag applied to your account the moment your number is ported out.
