Personally I really appreciate the fact that providers have SIMs. Verizon (major network in the USA) used to NOT have SIMs, and it was a huge pain to change phones out. Now it's as simple as swapping out the SIM.

I hear you that it should be doable in software, although I'd argue that if anything you should still need the SIM as a sort of second factor. (Otherwise you run the risk of people stealing your phone account remotely).

same! whenever i travel, i can get a sim card on that country and use my phone like i was using before.

without that, i would have to either buy a local phone or deal with how expensive my carrier makes to use internet outside my own country.
