Sort of yeah, it wouldn't be possible with my carrier for example as they would just tell you "login online and swap it" because things like switching sim etc. is just something you do there and not something you call them about. And to login to the website you must use the national 2factor authentication.
So essentially they would have to breach the national 2factor authentication system first here.
And there is absolutely no way that you could "social engineer" the guy on the other end of the phone who works for the telecompany as there is no way you shouldn't be able to use their online tools.
