While marketed as a free call and text messaging app, Mr. Number also has a call blocking features that can block calls from unwanted numbers or even calls coming from an entire area code. Such features allow the user to automatically hang up on telemarketers, as well as create a block list to prevent cold calls from coming through.

Just like Mr. Number, the Call Control app comes with a user-created and submitted list of spam and telemarketer numbers that can be automatically placed on the block list. Call Control, however, has "Lite" and "Full" versions, with the latter available for a certain amount.

Some smartphones come with call blocking features that users can activate and configure according to their preferences. On some Samsung smartphone models, the feature can be activated by going to Settings and turning on Blocking Mode. Exceptions are made by selecting numbers from the phone's Contact List to create an Allowed Callers list. The Auto Reject feature on other mobile phones can also be used for blocking unwanted calls.
