Hello all,
I just discovered that I had been using my sim-less phone to attempt to send some SMS's mistaking it for my physically identical working phone. Nothing alerted me to this, I discovered it by browsing the phones Messages app and several had stacked up by that time.
Im sure there are phones out there that alert to failed SMS by default, but evidently not Samsungs, so here is the Logcat data to detect a failed SMS and allow you to receive an alert.
Profile
Logcat Entry Component: System.out
Filter: Broadcasting: Intent { act=com.samsung.intent.action.SMS_SEND_FAIL pkg=ErrorCause (has extras) }
Attach any kind of beep/flash/say combo that appeals to you.
Enjoy and stay safe!
