I'm overseas - Can I get a SIM?
You certainly can, but not directly from giffgaff as unfortunately they currently only send SIMs to UK addresses. However many giffgaff commmunity members are happy to help, and will send a SIM to you abroad. Look for community members advertising that they are willing to send SIM cards abroad, then contact them directly
Please note that goodybags only work in the UK and giffgaff to giffgaff calls and texts are only free whilst you are in the UK. Using a giffgaff SIM outside of the UK will incur roaming charges. Details of the charges that will apply can be found here
