Is it possible to change my number please
Could you let me know and is it free

@Mark16 O2 will allow you one free number change. You will have to speak to customer service. All available numbers are in the link below. Getting through is difficult during the current crisis, so you'll need to be patient when you try calling. I've seen in other posts that the 0800 587 4005 seems to be the number of choice to start with.
