SMS Text to Raise Cellular Data Connection
Opengear cellular enabled console servers and wireless gateways can accept SMS text messages to trigger the cellular radio signal and connect to the carrier AP. This function is run from our Auto Response feature.
To get started, make sure SMS settings for the Cellular Modem are enabled:
Please Select "Cellular Modem" under "SMS Settings" on the SMTP & SMS Page
Please Select "Control via Auto-Response" in the Dial - Internal Cellular Modem page
Now, create two Auto-Responses - Cellular Up and Cellular Down
Cellular Down is similar, just change the message pattern to Celldown and the interface action to "Stop Interface".
Using the SMS text to raise and lower the cellular radio signal is a simple an effective way to contact sites for remote management.
If an admin or user forgets to SMS text the celldown trigger we also can run an idle timout scrip to watch over the connection for traffic and drop it when not in use to save on data plans.
The Idle timeout article can be found here.
