Welcome to the EE Community, @Leonblack02 🙂
If your SIM has been lost, stolen or damaged, please call 07953 966 250 to report it.
If you just need a different size (Check you don't already have a multi SIM that allows you to push out smaller sizes if required), you can order one at myaccount.ee.co.uk/app/order-sim.
Hope this helps.
James
