A simple solution of blocking unwanted calls on your Motorola cell phone is to redirect those calls to your voice mail. You will no longer be bothered by the blocked number. Transferring phone numbers to the voice mail is a simple process that will hardly take two minutes.
Add the number you want to block to your contact list. Go to "Contacts" and click "Add contact."
Enter the name and number in the respective field and save the contact in your phone memory.
Navigate to the "Contacts" menu on your phone. Scroll down to the contact you want to block. Press "Menu" key and select "Edit." Specify the option "Send straight to voice mail?" Select "Save." Click "Menu" and select "Contacts."
