Anti-Scam FAQ: What Is A One Ring/Wangiri Scam?

Answer:

When your phone rings only once, late at night, you may be tempted to call back. But the call may be from a foreign country with an area code that looks deceptively like it’s in the U.S. If you dial back, international calling fees may wind up on your bill. Such cons are also known by the Japanese term “Wangiri.”
