When I try to login to my account it asks me to choose a phone number so O2 can send me a code to sign in, but it only lets me select one phone number, which I do not use anymore, how do I change this number and sign in???

You need to contact O2.
Message them on Social Media. Facebook (https://o2uk.co/O2CFB) , Twitter (X) (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) or give them a call on 202 or 0344 809 0202 (contract) 4445 or 0344 8090222 (PAYG)
