How to Block Restricted Calls to US Cellular Cell Phones

Your Handset and Applications
1. Change the security settings on your phones. Specific models allow you to block phone calls from the handset. Check your phone settings and security settings on your phone. Consult the user manual for your specific cellular phone model for specific directions. You may need to call U.S. Cellular to verify that this feature will be supported by your cellular service.
2. Use an application designed for your phone. Several applications for phones like the Blackberry and Android will block calls. These may be free or available for a reasonable charge. Consult your specific phone's manual on how to obtain and use applications.
3. Use an outside service. Qwell will silence calls, but give the caller an option of breaking through if the matter is urgent. TrapCall will reveal the blocked number and give you the option of blocking it. Go to either website to sign up for the services (see Resources). Follow the onscreen instructions to set up call blocking. As of 2010, Qwell and TrapCall charges for their services.
4. Go to the Google Voice website (see Resources). Follow the onscreen instructions to sign up for an account and obtain a Google voice phone number. Google voice allows you to set up a Google number and restrict who can call you. As of 2010, Google voice is free of charge.You must have a Google voice phone number to block calls. Forward your calls to your Google voice number. Follow the Google voice instructions to block calls.
5. Register your cellular phone number with the National Do Not Call Registry (see Resources). This will prevent telemarketers from contacting you.
