@BLUEX are you talking about a Sky Mobile contract which does include all calls but has limits on the data usage in which case by definition you have a Sky sim or your home broadband service which can include a call package on the bundled Sky Talk landline? The latter has no sim as it only works on thee landline phone.

You can normally simpky switch mobile service provider as explained here https://www.ofcom.org.uk/phones-and-broadband/switching-provider/switching-mobile-phone-provider
