Blocking Phone Numbers

According to Straight Talk siste: "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. However, changing your phone number does not guarantee that you will no longer receive unwanted calls or text messages. To change your phone number, please contact our customer care department at the phone number 1-877-430-2355 or you we can assist you here. 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. Thank you."
