The question about location and sim

Hello, I am a user from Vietnam.


I would like to ask a few questions:


Previously, the ZA/A version was for Singapore. Starting from the iPhone 15 generation, was the code changed from ZA/A to ZP/A? Is that correct?


For the iPhone 11 Pro Max, was the ZA/A version configured with 1 nano-SIM and 1 eSIM only?


Was there ever a Singapore ZA/A version with dual nano-SIM?


If not, why do some iPhone 11 Pro Max units labeled ZA/A appear with dual nano-SIM?


For the iPhone 12, 13, and 14 Pro Max, there is also no Singapore ZA/A version with dual nano-SIM, correct?


Those dual nano-SIM models are Hong Kong versions, right?


If they are Hong Kong versions, why is the model code ZA/A instead of ZP/A?

iPhone 11, iOS 26

Only iPhone Air offers eSIM in China mainland. In Hong Kong and Macao, certain iPhone models feature Dual SIM with two nano-SIM cards.
