Hello @BigColin ,
Welcome to the community,
I take it you are on a monthly contract, as pay as you go there is no ESim, only physical sim card?
I would suggest ringing customer service, to see if they can enable it, otherwise. I take it you put the right code in, have you tried manually activating it, not sure whether you can.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using web based app or another phone: +44 800 079 8586 or +44 800 956 6000.
