SMS not working
My SMS texts will not send. I have checked the SMS setting and they are turned on. I have tried restarting my phone. All messages say “message failure” when not to another iPhone. What else can I do?
iPhone 7 Plus, iOS 14

SMS is a carrier feature, so contact your carrier. Note that for SMS to work you need to be connected to your carrier’s network (you need to see the carrier name and signal strength bars in the status line on your phone); SMS cannot work over Wi-Fi alone.
