I have an SMS flow launching today and I entered myself into the flow last night to test it. I received my opt-in messages, but the first SMS message failed to deliver due to "Device Disconnected" and I'm in the "Waiting" status for the second message.

My device is definitely still connected and I need help troubleshooting so this doesn't happen to my customers who opt-in today.

Hi @torip,


Thanks for sharing your question with us, understand the urgency and hope to help out here! 


Typically, the "Device Disconnected" error message could come up in a few different instances:

  • The destination number you are trying to reach is unknown and may no longer exist.
  • The device you are trying to reach is not on or does not have sufficient signal.
  • The device cannot receive SMS (for example, the phone number belongs to a landline)
  • There is an issue with the mobile carrier


However, if neither of this issues are a possible solution, additionally I would recommend investigating these additional possibilities :


I can see that you also opened a ticket with our support team and a member has recently reached out to you with a response. Happy to hear! Would you mind letting the Community know whenever you discover the solution, it could help other peers in a similar situation in the future!
