I need a different size SIM
Not a problem. Our triple SIMs fit all modern phones but if you have a SIM that doesn’t fit you can activate a new one and swap your number over any time 4.30am-9.30pm.
- If you have an unactivated giffgaff SIM at hand, log in and pop over to giffgaff.com/activate to activate that SIM. You'll be asked if you want to swap your current giffgaff number to the new SIM. Just follow the steps. There's no need to buy credit or another goodybag
- If you need a new SIM you can order one here, or buy one from a nearby shop. Any giffgaff SIM will do the job
