Why does sending a text message to a Japanese mobile phone only show success, but the other party can't receive it?

This has nothing to do with the phone, only with the number. Japanese mobile phones need to be swiped when they enter China, and domestic calling cards can only be used after they become the China version. It can be seen that each country uses an independent terminal for telephone communication. Not as good as other countries. So unless you use a calling card from the same country, you can't receive it normally.
