How do you stop cb masseges on note to phone?

To stop receiving CB messages (cell broadcast messages) on your phone, go to the "Settings" app, then find "Wireless & Networks" or "Connections." Look for "Cell Broadcasts" or "Emergency Alerts" under the "More" or "Advanced" options. From there, you can disable specific types of CB messages or turn off all notifications related to them. If you don't see these options, the process may vary slightly based on your device model and operating system.
