just got this in an email
90# on your telephone
I received a telephone call last evening from an individual identifying
himself as an AT&T Service Technician (could also be Telus or Bell) who was
conducting a test on the 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
I was further informed that this scam has been originating from many local
jails/prisons DO NOT press 90# for ANYONE.
The GTE Security Department requested that I share this information with
EVERYONE I KNOW.
After checking with Verizon they also said it was true, so do not dial 90# for
PLEASE HIT THAT FORWARD BUTTON AND PASS THIS ON TO EVERYONE
