Does the Verizon HTC One (M8) restrict GPS in China? This is a cross-post of "Why does my phone's GPS not work in China?"

Based on some of the answers and comments there, I am attempting to figure out what GPS sensor is being used in my phone, and what, if any restrictions Verizon and/or HTC and/or Google has placed on it.

I am currently in Beijing, China now, and have a China Unicom SIM card in my phone, not that it makes any difference - the GPS doesn't work with my Verizon SIM in either.

As far as I can tell, it doesn't. I was simply running into a classic "urban canyon" problem.
