Well Verizon is a special kind of "evil" from what i can tell.
In most places that's not as balkanized as the US carrier market, you basically get multiple SIMs for your plan and that's it. Nobody gets to question what kind of device you put those SIMs into.
From what I've read I've always got the impression that cell networks are one of the things the US is furthest behind in. Even when we are more or less technologically up-to-date, the customer experience part is still terrible.
