Yes of course you can Smiley Happy

If you have not yet done so, you need to first register the sim on Giffgaff and then activate it. Use the 6 digit sim activation code that came with the sim to register it. You then need to go to the Top-up page and top-up Online using your voucher.

Once your payment has been complete, your sim will activate within 24 hours and you will be given a new number.

Us you can. See here for process
Activate. a sim details. Log in here to start.

Enter the six character code and touch ". "continue "
Look at the address bar to see either MGM(member gets member) or freedom. MGM will mean the sim had £5 free on it. Freesim means the sim is standard and no bonus.
On this page you can pay by card or voucher(vouchers can be bought from shops displaying Pay Point etc banners). Follow steps to pay by card (the card has to be UK registered with a UK billing address ).
If you use a voucher look carefully for where it says " if you have top up voucher ". Touch.

The next page is personal details. Enter or change as necessary. Then touch "continue ".
This page gives a prompt for the 16 digit code on the voucher. Enter the 16 digits with no gaps then touch "redeem ".
All done.
The activation now starts.
Full activation can take up to 24 hrs. but normally it's only 30 minutes.

Sim actived? Check online here to see your new giffgaff number and your balance, when you see them your sim is activated.

Welcome to giffgaff! You have come to the right place. . . .

Giffgaff is CARRIED by the O2 network (although it is a separate entity) so you may use an O2 voucher to add credit to your SIM when you activate/register your SIM.

Then make sure you use the credit to buy the 'goodybag' of your choice before doing anything else, as the goody bag must be chosen; it is not assigned automatically.

Please don't forget to come back after your problem has been resolved and select a best answer.
