@Sandiemay , Have you upgraded to this new phone? Did you get it from EE? Are you using your original SIM card or are you trying to activate a SIM card that came with the new phone?
If you have your original SIM card, have you tried using it, as it should work, no need to change SIM card, it should then connect to EE network.
Your new phone will eventually show in your account, no need to worry about that.
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.
