Can you not call me now?
Just read over on Gothamist that starting February 5th, cell phone numbers are being released to telemarketers. You will begin getting sales calls on your cell phones. And of course, I can't imagine the telemarketers would be nice enough to call from an in-network number. So you'll be charged for the calls.
But never fear, you can get on the national DO NOT CALL list. It blocks your number for five years from credit card offers and magazine subscription inquiries. You can register your number very quickly by going here. It's like a spam blocker for your phone. By without the erectial dysfunction medication emails slipping through. In theory.
