@andym37041 did you top up by minimum ten pounds voucher to activate SIM as shown here and click on activate by voucher Only after doing this will Sim be given a number to use once completes your number will show here


Hopefully that helps out

Hi @andym37041


You need the voucher to topup as credit or purchase a goodybag at the same time as activating as It will not work,

For full instructions on activation see here:


Hope this helps.

I would wait a while & try switching your phone off then on again.
Follow the instructions on the card attached to the new SIM & wait up to 24 hours (usually 30 minutes).
Switch the phone on & off a couple of times.
When activated you should see Giffgaff in the top left hand corner of your phones screen.
If you still have a problem look at the following link:

You must redeem the voucher whilst you are registering the SIM card.  Without this, the SIM will never activate. 



I do not work for giffgaff, so cannot check anything on your account. This is a public community - please do not post any personal info.
