I ordered iPhone 11 Hong kong version but received other version. What are the differences between them?

Hello Suraga,

Thanks for using Apple Support Communities! I see you have a question about which iPhone 11 model you received, and I'll be happy to do my best to answer.

Keep in mind, iPhone models differ because of localized cellular technology and e-SIM availability.

If you go to Settings > General > About > Then tap on the Model number, MWN82CH/A, you'll see a number starting with the letter "A". Find the model number of your iPhone, iPad, or iPod touch

Compare that number with what is shown in this article to see which region iPhone you have: Identify your iPhone model

iPhone 11 tech Specs has additional information on the cellular radios.

Take care!
