Scammers overseas buy or steal lists of US cell phone numbers and use computers to mass dial. Your phone will ring just once-- long enough to generate a missed call. When you call back, the scammers charge you $20 for the call and another $9 for every minute you spend on the line.

The BBB said the calls usually come from numbers with area codes 268, 809, 876, 284 and 473. One thing to look out for is where the call is coming from. Many victims say the call location was Antigua.
