This action can send alert messages via SMS to your phone or mobile device. The message is sent through an SMS Gateway via the SMPP protol.
Pressing the Advanced button on the dialog above displays the configuration dialog below. This lets you customize the message text that is sent to you. This is most useful for trimming the size of the message that is sent to your device. You can also rename the action as it shows up in the various action lists. You can reset the action to its original/default name by simply clearing the name field.
If you're lucky enough to not be on call 24/7 you can use the Schedule button to specify when notifications should be sent to the given device. On off hours the action acts as though it isn't configured at all. The dark green below indicates 'on hours' and the lighter grey specifies 'off hours'.
