Obtain your cell phone's restriction code if you do not have it. You will need this code to access this area of your phone's settings. Contact the cell phone carrier's customer service. You will need to furnish the cell phone account information, such as the account holder's name, password for the account and billing address. Once you have provided this information, simply request the restriction code. The representative will be able to give you the restriction code based on the model number and manufacturer of your cell phone.

Step 2
Press the "Menu" button on your cell phone's keypad. This button is usually found in the top center of your phone's keypad for navigation purposes. Select the "Settings" option or icon that will be listed within your phone's menu. When the Settings menu loads, click on the "Security" action to configure new settings.

Step 3
Select the phone's "Call Settings," "Restrictive" or "Selective Call Block" option. (The text for the action may vary depending on the type of cell phone you have and the provider.) The "Security" panel will appear and you will be prompted to enter your manufacturer or cell phone provider's security restriction code before proceeding.

Step 4
Key in your phone's restriction code in the designated pop-up data form when the "Security" menu screen loads. Once the code has been accepted by your phone, you will be able to see the log of restricted numbers in your phone. To unlock the blocked calls, simply clear the restricted number you desire to enable by erasing its contents in the data form on the call log. Press the "OK" button in the lower right corner of the screen to apply these new settings.

Step 5
Test the settings by having the caller of the previously restricted number contact your phone. If the call comes through, you have successfully unlocked calls that have been blocked from contacting your cell phone.
