Step 3
Tap "Auto Reject List," and then select an option for blocking calls and text messages. To block messages from all unknown senders, enable the "Unknown" option; to block texts from a certain individual, tap "Create."
Step 4
Tap "Menu," and then select either "Contacts" or "Logs." Tap "Logs" if the number you want to block is not in your contact list but is one from which you received a call or text recently; tap "Contacts" if the person you want to block is in your phonebook.
Step 5
Scroll down to and tap the number or contact name you want to block. The Logs or Contacts screen closes, and the number for the person you want to block displays in the Number box on the Auto Reject Number screen.
Step 6
Tap "Save" on the Auto Reject Number screen to add the selected number to the blacklist.
Alternatively, you can contact your carrier and have the blocked.
Hope this helps!
