Is there a separate iPhone 7 for domestic and foreign use?

A. 1

Domestic and foreign use are different because each country uses different frequencies.

In the case of iPhone 7, we release a different version of iPhone 7 because the frequency varies from country to country.
However, there are many places that use the same frequency as Korea, so you can buy an iPhone that uses the same frequency.

There's a frequency division,
It's not usually just one frequency, but it's a way of grouping several frequency bands into several series
