Hi cricket. My name is NET10 Jhonally and I'll be addressing your question. We regret to inform you that all Straight Talk 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. You may also visit the FTC's Do Not Call Registry website: https://www.donotcall.gov/
to protect you from unwanted calls and text messages. Thanks.
