Hello @goziestifler ,
Welcome to the community,
If you are already a pay as you go customer with EE and needed a new SIM card, you should have requested a replacement SIM card. Did you not do this?
The store attendant was right, you cannot port your number over from the same network, but if you are coming over from another network, then you will need a PAC code from your previous network which you give to EE which ports your number over.
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.
