Good Evening . It's good to know that you've found your iPhone 5s, happy days .
If you recover a device that you asked Giffgaff to bar, you can ask an agent to unbar it. They will need its IMEI number, make sure to have it with you when you contact them (key in *#06# on your phone to display its IMEI). It is also possible to unbar a SIM card which has been temporarily barred. Ask an agent to unbar your phone
It does take up to 24 hours for a giffgaff agent reply to your request and then takes a further 5 working days for the unbarring process to be completed through the system, sorry.
Sorry @jojojames17077 if you report the SIM lost/stolen you will not be able to unblock if you found it again. You will need to wait for the replacement SIM to arrive.
Hi jojojames17077, this guide will sort it for you, good luck
