Get a cell phone service.

As a techo-challenged putz, explain to me why junk calls don't get through on cell phones.

As far as I know it is enforced by the cell phone companies. The blocks of numbers allocated to cell phones cannot be used in autodialers. To get a call from a business you have to give them your cell phone number.

I believe the determining factor is the competition in the cell phone market, not regulation although there might be some regulation also.
