How to Block Messages on an Android

1. Download a message-blocking application from the Android Marketplace. Your choices include Cold Shoulder from appbrain.com, chompSMS from chompsms.com or sms Blocker from android.com. Tap the 'Marketplace' icon on your Android, then search for the app and download it.

2. Open the blocking app by tapping its icon.

3. Block the number that is harassing you. In chompSMS, tap and hold the screen over a message from the number you want blocked. A menu appears; select 'Block.' In Cold Shoulder, type the number you want blocked into the 'Block New Number' field, then tap 'Add.' Choose the stock reply message, or enter a custom message. In smsBlocker, tap 'Block,' then 'Add New' and enter the number you want blocked.
