I'm planing to switch to this provider from O2, as they are considerably cheaper
However, I am really concerned that I wont be able to receive calls to my current number. They are supposed to have a process whereby you can keep your old number - has anyone any experience of this?
Also, I know this sounds like a really amateurish question but is information on your phone (i.e. phone book) saved to the SIM or to the mobile on typical Nokia phones?
