国外电话怎么打

To make an international call, you typically need to follow these steps:

1. Dial the international access code (usually "00" or "+").
2. Dial the country code of the country you are calling.
3. Dial the area code (if applicable) and the local phone number.

For example, if you are calling a number in the United States, you would dial: 00 (or +) - 1 (country code for the US) - area code (if applicable) - local phone number.

Remember to check with your phone service provider for any specific instructions or requirements for making international calls.
