Hello, this is Andy.

Everyone, when your friends travel to Japan, how do they use their mobile phones?
Do they rent pocket Wi-Fi? Or do they use international roaming from their home country?
Thanks to two major technological advancements in recent years, I feel that renting Wi-Fi or relying on expensive international roaming is no longer necessary.
-
The advancement of smartphones has enabled widespread support for dual SIM (allowing two SIMs to be used and switched as needed).
-
The development of software and network technologies now allows users to purchase SIM usage rights and activate them via software.
Even Rakuten Group offers eSIM as a shareholder perk.
By scanning a QR code, users can easily install an eSIM on their iPhones.
Given this situation, it seems that using eSIM during overseas travel is the best choice instead of Wi-Fi rentals.
So, this time, I’ve conducted a price comparison of eSIMs in Japan.
I would like to choose eSIM services from KKday, Airhub, or Mobimatter while in Japan.
