It has been brought to my attention that there is a new scam going around where you receive a text message pretending to be from giffgaff stating that your sim is not activated, whatever you do . Do not click on it as it will kill the sim card.
Any genuine link sent by Giffgaff will have a giff.ly or giffgaff.com type link contained within the text.
Such incidents should be reported here https://community.giffgaff.com/t5/Announcements/Keeping-your-giffgaff-account-and-personal-details-secure/td-p/23688816
Thanks for heads up
