The Apple Store in Hong Kong, which I visit every year at this time of year, can't beat the Corona sword this year.
The purpose is a DSDS Hong Kong version iPhone that can insert two physical SIMs.
For overseas business trips, it is the strongest to use cheap local data communication while receiving calls and SMS from Japan by inserting two SIMs, a Japanese SIM and a local SIM.
The Japanese version is also dual-simmed with eSIM and physical SIM, but the eSIM support of the three major carriers has not yet been realized, and the original convenient usage is not possible.
This year, next year and overseas business trips are uncertain, but I also got the Hong Kong version because it has the advantage of being able to wait for two carriers at the same time even if it is placed in Japan.
Since it is obtained by relying on the local route, it arrived about 10 days after its release in Japan.
For the time being, I changed au's SIM to a 5G plan, and both Softbank and au are recognized without problems.
Apparently, a bug that only 4G can be caught with dual sim in 5G? There seems to be something like this, and there are rumors of a response within the year.
Well, there is almost no place to grab 5G, so is it okay for a while?
However, the dual sim version is comfortable without the camera shutter sound.
