How do mobile users send short messages to Japan?

Because there is no GSM network in Japan,

Therefore, when roaming in Japan, we usually rent a dedicated mobile phone on the road.

If your girlfriend has gone through the formalities of international roaming in Japan, that's fine, but your girlfriend will actually stop. I think she must not have gone through the formalities of international roaming in Japan (international roaming requires prepaid phone bills, so she will definitely not stop after international roaming. ) Then I'm afraid you can't reach her.

You text her in the right way, even if you call, you dial directly.

3. She didn't do international roaming in Japan, and her mobile phone certainly didn't have internet.

4. Mobile phones roaming in Japan, send domestic mobile phones (each) 1.99 yuan/department.

Send Unicom mobile phones (each) 2.04 yuan/article.

And if you send her a text message, if she can receive it, she will only charge you for domestic text messages. And receiving text messages is free.
