What Happens When SMS Messages Cannot Be Delivered?

When an SMS message cannot be delivered, Convergence alerts you in the following ways, depending on whether you are using one- or two-way SMS:

• Two-way SMS: The undelivered message is badged with a warning icon in the SMS messages tab. If you mouse over the warning icon, information that the message was not delivered is displayed.
• One-way SMS: You see a Non Delivery Notification (NDN) as a regular email in your INBOX. The email is badged to indicate that it is an NDN related to an SMS message.
