@ForzaVerde , did you cancel it or ported it to another network? If you ported it to another network, then you would have to get a PAC code from your previous provider to give to EE, but if you cancelled and do not have the number active at all, you are more than likely not to be able to reactivate it as @XRaySpeX has written.
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.
