There is a phone scam going on that is racking up huge charges on cell phone bills. They call it a "One Ring Phone Scam". A phone call comes in, usually only rings once then the caller hangs up, and it shows up as a missed call on your phone. You call it back, and you're slapped with international phone call charges. I mean charges to the tune of $19.95 just for calling, and an additional $9 for every minute you're kept on the phone! The Better Business Bureau warns of this scam, and gives area codes you should beware of.
