Well that kinda limits the competition a little....
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)
I heard that was coming, but for a different reason. Not sure if true but seems like P4U were causing O2 a major headache by catching customers out and putting them on new contracts rather than upgrades. Extra commission for P4U, and customers being left with 2 accounts, and O2 having to pick up the pieces.
