Hello and welcome to the community yes you can change your giffgaff number
(without changing your SIM ). Please be aware that you have to top up your credit by £10 (this is added to your credit balance - it is not a charge). All other sims details will be unchanged (credit, goodybags etc) Full guide here - http://bit.ly/kbggchange The agents will contact you with details of how
Select incoming calls from the list of call types to bar, (otherwise the form will not send, If you do not want to bar unwanted incoming calls, add a note to your message.)
In 'Any Further Info', ask for your giffgaff number to be changed for a new number. It will take the agents up to 24 hours to reply.
You will be asked to confirm that you understand a £10 top-up is required to activate the new number. Do not top-up until instructed to do so.
When your new number is ready, you will be given instructions on what to do next. Follow the instructions to add the £10 top-up and activate the number change. This money will be added to your airtime balance.
Wait while the new number activates and you're good to go.
Depends whether you want a diferent random giffgaff number due to nuisance calls, or want to port your old number from your previous network? Either way, wait until the current fault is completely cleared - check on the Service Updates forum.
