Hi there and thanks for visiting the community.
You could always perform a sim swap.
When you perform a sim swap,ALL credit and any remaining goodybag/Gigabag allowance,along with your giffgaff phone number and any payback that you currently have,is transfered to your NEW sim card,,,easy.For members who wish to change from a standard size sim card,to a micro sim card,just check the middle of your current standard size sim card.It should also have a micro sim card that simply pops out in the middle of your standard size sim card,if not,do you have a spare ( un-activated ),giffgaff sim card ?.
If not,dont worry,simply order the correct sim card size,by clicking onto your "Spread giffgaff" or click onto the link below 😉 http://giffgaff.com/spread
Then simply,perform a sim swap 😀 .
Please take a look at a great guide,by clicking onto the link below.http://community.giffgaff.com/t5/Using-giffgaff/What-is-SIM-Swap/ta-p/7320084
