And then there’s dual SIM (or even quad SIM). It’s a feature
that’s really popular in Asia and Latin America where people
might use one network for a local call and another for an
international one. That’s largely something MediaTek drove,
but now it’s in the Moto E, which also has a feature called
SmartCalling to help people set up and swap between SIM
preferences and automatically configure access point names.
You know what would be cool? If your phone knew how much
bandwidth from each carrier cost, and could switch between
them on the fly, depending on which one was cheapest, like a
multi-SIM phone that didn't suck.
