Use the SMS Sync column to notify a client application that it needs to synchronize data with the server. This notification is a message sent to the mobile device. If the client application on the device is programmed to listen for alerts and to act on them appropriately without user intervention, the client application will perform the synchronization.
Before you can use the SMS Sync column, you must use the SMS tab to set up the SMPP connection for your SMS provider, as described in Using the SMS Tab.
