Reactivate expired sim

Hi, How do I reactivate an old giffgaff sim - i let it expire by mistake as it is an emergency phone I leave in the car
Thanks

annemlawson Hi sorry but after 6 months of non use the SIM is cancelled and the numbers recycled !
So you will need a new SIM and number !

annemlawson sorry but once a SIM has been deactivated it cannot be reactivated.

You should start from scratch by getting and activating a brand new SIM.

You cannot!!

New SIM required, with a new number.

I've lost my sim card

Order a new SIM from: https://giffgaff.com/orders/mgm ; or pick one up at local shop.

When it arrives, perform a SIM swap. https://community.giffgaff.com/t5/Using-giffgaff/What-is-SIM-Swap/ta-p/7320084
Your current number and any goodybag / credit transfer as part of this process.
Don't forget to back up any contacts on your SIM as these do not transfer as part of the process.
You can only do a SIM Swap between 4:30am and 9:30pm.
It may take several hours to complete; very occasionally it'll take 24 hours.
