Why can’t the eSIM be fully activated while outside of Japan?

🅰️Our eSIM uses the local docomo mobile network in Japan, so it can only receive the signal after entering Japan. Once the signal is received, it will automatically activate immediately.

【Note】Most of the eSIMs currently available on the market are international roaming eSIMs sold by telecom companies from various countries in Taiwan. This is why they can be set up before traveling abroad, and you need to turn off roaming while outside Japan and enable international roaming after arriving in Japan. Since our eSIM is a local product for Japan, you do not need to enable roaming.
