Why is FT Audio disabled?
Well no kidding I should have signed up in BJ or SH, but I don't have other roaming plans. PVG airport sold traveler SIM on arrival (Y150 for 10 days) which is 4 months of postpaid service. I didn't buy one there because I assumed CTU would have traveler SIMs but they didn't. No one needs a SIM here apparently. The current plan is fine for me I guess, but I'll try to change plans today
No one knows except for Apple:

FaceTime is available in almost all countries around the world, with the exception of the United Arab Emirates. To use FaceTime in Saudi Arabia, an iPhone or iPad must be running iOS 11.3 or later, and to use FaceTime in Pakistan, devices must run iOS 12.4 or later.
Devices purchased in certain Middle Eastern countries will also block FaceTime if a SIM card from a non Middle Eastern country is inserted. FaceTime Audio is not available in China. All iPhones and iPads sold in China are limited to the standard FaceTime with video feature.
Note that if you purchase an iPhone or iPad in China or the United Arab Emirates and then attempt to use it in another country, the FaceTime features listed above will be disabled. Purchasing an iPhone from China or the Middle East is not recommended unless you live in those places.
