And while there's a larger online marketplace for phones than ever before, the truth of the matter is that most people in the US buy an iPhone, Samsung Galaxy or LG device directly from their carrier.

This mobile trinity is frustrating for adventurous types, especially when phone reviewers like me point out models that are worthy of your time and attention, but aren't available on a carrier. So, what gives? Why can't you get any Google, Motorola, Huawei, Xiaomi or Sony phone you want from any carrier you'd like?
