I don't know if I have to plug in the phone number after *77. I don't know how, if I have already picked up the receiver, that #01# could work. I tried the latter yesterday, the guy on the other end laughed and said, "he is trying to block me." So I hung up. Please explain in everyday English, non-technical.
