@DMM1 

You can do a sim swap yourself Guide: Sim Swap: a mini guide 2017 update 

or login to your MyO2 and change your security question and answer under "My Details"

I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
Please select the post that helped you best and mark as the solution. This helps other members in resolving their issues faster. Thank you.
