Class 0 SMS (Short Message Service) text messages aren't stored in the memory of the message recipient's cell phone. Unless saved upon review by the message recipient, Class 0 SMS text messages disappear after being read. Class 0 messages can also be used to "ping" another cell phone. They can receive confirmation of a recipient's messaging capabilities without the recipient even knowing they were pinged. While Class 0 messages can be abused, they can also be an effective troubleshooting tool for SMS communication.
