If swapping from PAYG to contract you need to call O2 to swap your number. Guide: Coronavirus Community Help and Support
If you are staying on the same type of account, you can do a sim swap yourself Guide: Sim Swap: a mini guide 2017 update
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.
