The OP was talking about LTE bands. Those are identical between the 2 iPhone 7 Plus models you cited. The difference between them is that one of the models supports CDMA and TD-SCDMA. I agree that this could impact roaming experience in China, and Apple's own web site says as much.

OP, what kind of phone are you using?
