O2

Hi I recently went from pay and go to pay monthly. I have now been pay monthly for around 5 days. On my o2 it has correct phone number(kept my old number) it is showing the wrong device though, it shows I still have my Samsung Galaxy J5 and not a Sam...

How long does it take for my pay monthly service to activate itself and how long will it take to transfer my o2 pay and go number to my o2 pay monthly number. I want to keep the same number and have filled out the form to the best of my ability.
