I cant change my address on my O2. The help page doesnt match the actual website. I finally find manage my details and it says select an account on MyO2 and takes you back to the begining.
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.
Currently using: Pixel 7a (O2 & Lyca), One Plus 6 (Sfr), iPhone 12 Pro Max (Vodafone)
