I recieved a call from this number. And at first there was dead air, and I persisted and said hello and I finally recieved an answer. It was a person (sounded like a novice telemarketer from the hesitation in his voice) claiming to be from SPRINT. They wanted to upgrade me to a new phone. I asked, "why are you calling from a 973 number not a 1-800 number" and he said they were in New Jersey. Of course I know 973 is in New Jersey, but if you really were official you would call Toll-free. I didn't push this point. It seemed all very sketcy and I declined any further conversation with the person on the other end.
