How do I block calls on my cell phone?

Traditional Do Not Call Lists can be very effective at preventing legitimate businesses from performing telemarketing to landlines (wireless numbers do not need to be included to avoid unsolicited calls). However, they do little to prevent scammers and robocalls. An estimated 65% of complaints to the FTC in 2016 were for recorded messages. In 2015, the FCC clarified rules that made it possible for cell phone carriers to start offering call blocking services and continues to push for additional changes in 2017.

AT&T offers Call Protect for free to customers with eligible devices and plans.
Verizon does not offer to automatically block scammers, but it does offer to block calls from up to 5 different numbers for free.
T-Mobile offers Scam Block for free on all postpaid plans.
Sprint offers to identify but not automatically block spammers through its Premium Caller ID service for $2.99/month
