CLEVELAND -- The Better Business Bureau is warning about a new scam that can rack up unauthorized charges on your monthly cell phone statement.

It's called the "One Ring" scam, because the people behind it call your cell phone, let it ring once and hang up.

If you call back, you can be charged $20 for an international call fee and per-minute charges for "premium service," which can be $9 per minute or more.

Calls usually come from numbers outside the U.S.

A Cleveland woman who reported the scam told the BBB her caller ID indicated the call originated in Antigua or Barbuda (268). Other consumers across the country report calls from the Dominican Republic (809), Jamaica (876), British Virgin Islands (284) and Grenada (473).

The practice of a third party putting unauthorized charges on your bill is called "cramming."

The Better Business Bureau says, if you don't recognize the number on your caller ID, don't pick up and don't call back.

Also make sure you check your monthly statements. If you see something you don't recognize, contact your carrier immediately. The earlier the fraudulent charge is detected, the better your chances of having it removed.
