Check the status of a sent SMS

Double-click the Headwind GSM modem driver icon in the tray to open the control panel. The recently sent SMS must be in one of the folders "Outbox", "Sent", "Failed". If the modem is not connected, the SMS will be in the outbox. It is not sent, but it will be sent after establishing a connection. If the SMS is sent normally, you will find it in the "Sent" box. In the case of an error, the SMS is placed in the "Failed" box, where it can be accessed and resent.
