When did you activate your SIM? Check your 'my giffgaff' page to see if you have a number allocated to you. If you do, your SIM is active. If that's the case, your phone may be locked to another network, in which case, you'll need to contact the previous network or check out eBay for sellsers with codes to unlock the phone.
Hope that helps
Most of the activations are processed within a few minutes but it can take up to 24 hours in some situations. Keep restarting your phone now and then.
You can check if your SIM has been activated by logging in to "My giffgaff". When the SIM is activated, your new giffgaff number will be displayed under your name and your credit and/or goodybag will also be shown.
If your SIM is not activated after 24 hours, please contact our agents so they can verify the status of your activation.
