Good Evening @joanp0563 🙂 . If your Wife is leaving giffgaff for another mobile provider, she'll probably want to keep her phone number. To transfer mobile numbers, she will need to give a Porting Authorisation Code (PAC) to her new network. She can ask for her Giffgaff PAC here. Alternatively, from your Wife's handset, please dial 43431 and follow the instructions.
She will receive a voice confirmation of her PAC and its expiry date which will also be sent via a SMS message. This will also be displayed on her My giffgaff (Dashboard) page under her mobile number.
She will be sent her Giffgaff PAC via a text within 2 hours between the hours of 8.00 am and 4.00 pm Monday to Friday.
Please remove Payment Details (credit/debit card or PayPal) and to turn off (disable) any recurring goodybags or top-ups in your Payment Settings she may have active, to avoid future automatic purchases.
