giffgaff and keep a number
giffgaff is a digital-first provider on O2 infrastructure. Its account and community help routes are separate from an O2 account.
giffgaff: Keep login and verification codes within giffgaff’s verified account journey. A PAC moves a number; it does not settle any separate handset responsibility.
The terms that matter are those attached to your own service. An independent information line cannot view the account or confirm an individual balance, eligibility or coverage outcome.
