@VictoriaOlm19 , Have you reported your phone as lost or stolen? I would strongly advise you to do so and then either go into an EE store and ask for a replacement SIM card or you can order a replacement SIM card either by ringing customer service or you can do this via the My EE App and then clicking on the three lines at the top and then going to settings and you will see device and sim and can then order a replacement, hope this helps.
Sorry, yes did not read the whole of it, as @XRaySpeX has written, you will need to activate it here first.
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.
