Understanding International Calling

International calling brings people together from different continents, but it also comes with steps and costs of its own. 

When calling another country, there are rules to follow, including the need to have an exit code (to exit your country’s network) and a country code (to reach the destination). Dialing Japan from the US starts with the US exit code (011), then Japan’s country code (81).

Charges may vary depending on the service provider, the duration of the call, and whether you are calling a landline or a mobile number. 

More economical alternatives use VoIP services like Skype, or WhatsApp, for example.

Also, being aware of time zone differences is important so that communication occurs at a convenient time. International calls can be easier and affordable if you plan your calls and are aware of the number format.
