Hi leothelion89. My name is NET10 Sophie. We regret to inform you that all NET10 phones do not have the feature to block phone numbers. To stop receiving unwanted calls or text messages, you may have your phone number changed. However, changing your phone number does not guarantee that you will no longer receive unwanted calls or text messages. On the other hand, you may visit the FTC's Do Not Call Registry website: https://www.donotcall.gov
to protect you from unwanted calls and text messages. Also, the web browser feature on the phone can't be blocked. Just keep your keypad lock when not in use, to avoid unnecessary charges. Thank you.
