I called verizon again per Ross suggestion. This time a more experience rep. said most not true. I never tried these false tips myself, but was concerned a e-mail I got not true. So I called verizon and talked to a Rep., a young gal said she tried on her personal cell phone as I read her the four instructions and she said all worked. I believed her. I also got a call for feedback on my first call and gave her AAA+ rating. I guess it's true a sucker born very minute. Sorry for the false info.
