Hello @Lea95 ,
Welcome to the community,
You will have to ring customer service to get this activated, but may just want to leave it in your phone and see if it activates automatically by also rebooting the phone. See below how to contact customer service.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using Skype or another phone: +44 800 079 8586 or +44 800 956 6000.
