Calling back number you do not know can have bad results. there is currently a 1-ring scam going on. They call, & have no intention of talking to you. They want you to call them back. Your call goes to a Caribbean nation, international rates apply, & then you find out you've dialed a premium rate number. Always check the area code, and number FIRST.

This number calls me every now and then. Never picked the call but try to call back without luck.
