Can I use the existing iPhone in Japan?

A. 1

In Japan, I have to cancel Country Rock to change the USIM chip and use my iPhone as it is.
It's a restriction on other carriers and overseas use by carriers.
You can only use the Japanese local USIM chip if you cancel it.
To do so, you can call the carrier and ask for a cancellation.

Apply for the cancellation of Country Rock first.
And then you have to synchronize it with iTunes.
