I just purchased the eSim monthly plan on ID Mobile on the mobiles.co.uk site. However, there wasn’t an opportunity to provide my PAC code as I am coming from O2.

I want to keep my old number from O2.

I’ve just created an ID mobile account, however it is asking me to register a mobile number. Should I be activating my eSim first to get an ID Mobile number? I am unable to login and proceed further without this new ID Mobile number - but I don’t want a new number as I want to keep my existing one that I use with O2.

I can confirm that I’ve received an email from ID Mobile saying that my eSIM is ready and I just need to activate it - should I complete this bit first?

What steps should I be doing please - your help is much appreciated!
