Can I pay for an iPhone in cash in Hong Kong?

Hello EunsuHa,

Thank you for using Apple Support Communities. Payment methods accepted would vary on region and store policy. The best approach to take is to contact an Apple Store in Hong Kong to see which payment methods are accepted there. To get a list of Apple Stores in Hong Kong, use the following link here: Apple Retail Stores

You'll see a drop down menu, click on that and select Hong Kong. You can also attempt to locate an Apple Authorized Reseller as well. This link can help you locate one: Find Locations - Apple

Just input the postal code and the device you're looking for to populate a list.

Thank you for using Apple Support Communities. Best of luck.
