Qualcomm has bullied players like Samsung to prevent them from using their own LTE modems, and has done everything possible to ensure they are the only reasonable choice for LTE chipsets.

In Samsung's case, only Samsung branded devices can have their LTE modem per the settlement with Qualcomm, and US bound phones always ship with a Qualcomm SoC (part of that whole home territory thing for Qualcomm).

Another affected group is Mediatek, they only recently got LTE support, and their ability to get chips with LTE is entirely controlled by Qualcomm. There is no competition in the modem space, which is absolutely appalling.
