And the answer basically amounts to, although we do have some protections, we can still be screwed:Q: Regarding the sole use of wireless phones as an alternative to a land line connection, as I have done for nearly two years: You stated that tele-marketers do not call wireless phones. If only that were the case. Tele-marketing agencies have regularly contacted me on my cell phone concerning everything from vacation homes to long-distance service. My assumption is that these agencies secure my cell phone number by buying information from the plethora of forms and applications that require home telephone numbers but leave no place for a cell phone.
Does anyone have any advice on things I can do to get these tele-marketers to stop calling on my cellphone?"'A: [...]In short, John, you lost your chance at a telemarketing-free life when you filled out those forms with your phone number. May others learn from your mistake.'
Most land-based phone companies allow anonymous-call blocks these days. Are there cellular phone companies doing anything similar?
