For the sake of your privacy, much less possible expense of additional
incoming phone calls, I urge you to write to your Senators and Congressmen
to support passage of Representative Edward Markey's proposal ("Wireless
411 Privacy Bill")as soon as it is presented for a vote.

For more info on the proposal, please check out this link-

Personally there is NO way that I would trust ANY wireless carrier to
police/administer this on their own.
