How to Block Unwanted Calls to Your Cell Phone

Phones with Native Phonebook Blocking Features

Step 1

Press or tap the "Menu" key or button.

Step 2

Select "Settings" and then "Phone" or "Phone Settings"; then tap "Calls" or "Incoming Calls."

Step 3

Press or tap "Blocked Callers," "Blacklist," "Unwanted Calls" or other similarly named menu option. After selecting the appropriate menu option, your contact list or phonebook appears on the screen.

Step 4

Select the name of the person from whom you do not want to receive calls and press or tap "OK" or "Block." If the name of the person is not in your contact list or phone book, enter his phone number in the number field and select "Block" or "OK."

Step 5

Exit the menu screen on the phone. After you block the person, calls from the number no longer appear on your screen nor cause your cellphone to ring. A caller on your blacklist hears a busy signal when he attempts to call or hears a message stating that you do not accept calls from his number.
