How to Block Cell Phone Callers

By James Clark

Put a stop to annoying cell-phone callers by adding their number to your "blacklist." Most cell phones offer a security feature that allows you to enter about a dozen numbers that you wish to block. Once the number is added, your phone will not ring, although the caller may be able to get through to voice mail, depending on the type of cell phone. Threatening calls should be reported to the police.

Things You'll Need

  • Cell phone and passcode

Step 1

Activate your phone and choose "Settings" from the main menu.

Step 2

Scroll down to "Security," press "Enter" and then enter the security code for your phone. If you've forgotten your code, most cell phones use a default passcode that is either the last four digits of your telephone or social security number. If you still can't recall the code, you will need to contact your service provider.

Step 3

Choose "Selective Call Block" (or similar choice) from the list of choices.

Step 4

Enter the number that you want to block, including the area code. Press "Enter" to block the number.

Step 5

Repeat the steps to access the call block feature if you ever wish to delete a number from your blacklist. Some phones allow a certain maximum number of blocked callers, but after a few months of blocking a number, the nuisance caller may have given up and so you may be able to delete that number and free up a space for blocking a different number.

Step 6

Register your cell phone number for free with the National Do Not Call Registry to stop annoying telemarketer calls.

Tips & Warnings

  • Report threatening calls to the police, who can investigate and bring criminal charges against the harasser.
