How many times, do you happen to get to the phone just when it has stopped ringing? One of the family will shout out "who was that on the phone?"
You check and find it was from a phone number, which you do not recognise. You find it most infuriating as you cannot put a name to the caller. But wait, all is not lost as your son shouts out " you should get reverse call finders". You are completely unaware that it is possible to put a name to a caller from a cell phone.
