I use these following at+commands in vb.net to send sms

AT+CMGF=1
AT+CMGS="PHONE NUMBER"
>HELLO WORLD

How am I going to determine if it really send or it fails to send? I want to know the real time status of my message

I'm expecting like say for example. I hit send, there will be a messagebox showing "Sending" then after a couple of seconds, it will change into "Message Sent" or "Sending Failed"

  • Add a guess would think this is whole dependant on your SMS server responding in some fashion. Weather that be some form of error response, time out, a simple boolean or otherwise. Without a little more context, not sure you're going to get much more info sorry – Hursey May 17 '23 at 20:58
