I knew someone before that didn't want a record of the phone calls he would make, so he said ( on cell phones only) you could take the battery out
and put it in the freezer for I think it was 3 hours, and you put it back in . You could make calls for about an hour and there will be no record of
the numbers . I saw one of the phone bills and there were sections of several 00000000000000. The phone company had no record either. It works!
