If you've lost your phone and/or SIM while abroad, make sure to report both as lost so we can block them. That way, no one else can use them and your account stays safe.
By doing this, giffgaff will send you a replacement SIM pre-loaded with your number. Please keep in mind that it'll be sent to your home address, so you'll be without service until you return.
Useful tip: It’s a good idea to take a spare unactivated SIM with you before you travel abroad, just in case anything doesn’t go to plan. Better safe than sorry.

If you have an unactivated giffgaff SIM with you
Log into your giffgaff account (you'll need access to your registered email for verification)
Go to the SIM card area in your profile settings
Follow the instructions to activate the new SIM and swap your number over (Keep in mind that while you can perform a SIM swap abroad, it's advised to wait until you have connection to a UK network)
If you don't have a spare SIM
If you don't have a spare SIM
It would be worth using a local SIM until you return to the UK. Once home, you can then get a replacement SIM, or an unactivated SIM to perform a SIM swap.
Note: Due to the ongoing security tests that might hold up your MFA code, switching to an eSIM while abroad is not possible.
