If your SIM is damaged, just stops working or is the wrong size for your phone then the best solution for you is to perform a SIM swap which will give you a brand new functional SIM card.
SIM swaps should be performed when
Your SIM has become faulty or ceases to work
You need another SIM of a different size to fit your phone
You have or can get an unactivated giffgaff SIM of any age to do the SIM swap
You don't need to report/bar your phone
The process of ordering a SIM and doing the SIM swap procedure is much faster than reporting your SIM lost and has several advantages, one being that you can usually be up and running the same day if you have a spare SIM handy.
If you don't have a spare unactivated SIM then you will need to get one, you can:
Once you have a SIM just login and go to the SIM swap page and follow the instructions or have a look at the dedicated SIM Swap guide.
giffgaff SIMs are now 'All in one SIMs' and the SIM card contains a Nano, Micro and a Standard [mini] SIM. Have a check of your SIM, you may not need to swap at all. Just pop out the section that you need.
If you have received your SIM and the activation process fails due to a SIM fault then we'll need to replace it for you. Please Ask an Agent by filling out the form with the information for the faulty SIM card and we'll put a replacement on order straight away.
Please check the address on your account so the SIM goes to the right place. You can check it here.
Note: Activation can take up to 24 hours. Please wait for this delay to expire before contacting the agents as they won't have the information yet.
