Hello @NicShelbourn ,
Welcome to the community,
Sim cards are sent out via second class post, but if you are near an EE high street store and have a valid photo ID, you could get one there.
Not sure why your previous plan has been cut off, but you would either have to use another phone or a web based app to ring customer service, there is no email nor is there webchat unless you have a monthly contract.
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.
