How to call California, USA? My friend is in San Francisco, California. they ...

Dial: 00 1+4 15+* * * * * * (* stands for the other party's phone number) with a phone that can make international calls.

The area code of San Francisco is 4 15. We need to add the international long distance identification number 00 in front of it. Because it was sent from places outside 4 15, we need to add 1 before the area code, so the final number should be: 00 1+4 15+7 digit telephone number.

For example: 0014158123237.

If you send a text message, your friend's mobile phone will display your number, including the area code and so on. He can just reply directly ~ ~ ~
