Re: changing telephone number

@Diana2 did you report the loss to O2 ? 


Either way, you need to call customer services to activate the new sim with your number. 


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.
