Hey Mheagerty! We apologize for the inconvenience. Can you please verify any of your services is malfunctioning? Are you able to call/receive calls, send/receive regular text messages and have access to the internet? Can you as well please provide us the make and model of your device?
Hello, Me80. Thank you for contacting us. Facebook is a third-party application and they do not send as SMS to your phone unless you set up the phone to do so. When installing "messenger" (Facebook messaging tool) it will give you the option to show your messages as an SMS. We suggest you to uninstall and re-install the application and check that option. As a last resort, we can suggest that you contact the manufacturer in order to get the assistance needed.
