How do I call to overseas number?

To call a number in another country, dial 00, and then followed by the code for the country you are calling, the area or city code, and the phone number. For example, if you are trying to call someone in Brazil (country code 55), in the city of Rio de Janeiro (city code 21), you would dial 00-55-21-XXXX-XXXX. For your convenience, you can also replace 00 to + e.g +55 21 XXX-XXXX.
