Case Details

I was charged a lot although I didn’t use my smartphone during an overseas trip.

When I went on a trip abroad, I was charged a large amount of money although I didn't make a phone call, e-mail, app using a smartphone phone. I can’t accept this.


The “international roaming service” that allows you to use your smartphone overseas is very convenient. However, the charge system is different from that in Japan, so you may be charged at a high price.
When traveling abroad, check with your mobile phone company before the departure, check the setting method and billing method, and take necessary measures.
