Hi. We have an eWon industrial router with alarms and datalogging functions on site and were wondering could we use it to send SMS rather than Airlink LS300 from Ignition.

my understanding is that only the sierra wireless modems will work.

You should look into the twilio module. it works great and is inexpensive.

Thanks diat150, that’s what I though there was only 2 Sierra modems that work.  
Must look into the twilio, hadn’t heard about it
