90# on the telephone
This just happened to my friend. I received a telephone call last evening from an individual identifying himself as an AT&T Service technician who was conducting a
test on telephone lines. He stated that to complete the test I should touch nine(9), zero(0), the pound sign (#), and then hang up.
Luckily, I was suspicious and refused.
Upon contacting the telephone company, I was informed that by pushing 90#, you give the requesting individual full access to your telephone line, which enables them to place long distance calls billed to your home phone number.
I was further informed that this scam has been originating from many local jails/prisons. I have also verified this information with UCB Telecom,Pacific Bell, MCI, and Bell.
