Telemarketers can not call your cell phone using an automatic telephone dialing system (a computer) or an artificial or prerecorded message to any wireless telephone number.

A cell phone can be called, as long as the cell phone number was dialed by hand, unless the cell phone number is on the Do Not Call Registry or you have made a specific request to the same caller, prior, requesting to be put on that callersDo Not Call in-house list.
