Hi there and thanks for visiting the community.
If you would like to change your current giffgaff phone number,then,YES that CAN be done. simply,visit or click onto the link below and contact a giffgaff agent.http://giffgaff.com/support/ask/call_barring
1) Select incoming calls.
2) Select "yes" onto the option,(do you wish to have your number changed).
Once you have your NEW phone number,you will be required to ACTIVATE your NEW number,with a minimum top up of £10 or over.
Any remaining goodybag/gigabag and credit,will still REMAIN, and ONLY your number will change.
A reply from a giffgaff agent,may take up to 24 hrs,during busy periods,so be a little patient if you can.
