The SMS module is made for Sierra Wireless Airlink models and the protocol it uses. It’s unlikely your modem will work unless it’s one of these.

I may be wrong on this but I believe that the PTP(Point to Point) protocol is actually used between the Modem and the ISP Carrier - This part should have nothing to do with Ignition.

Ignition will trigger an “Event” and the Modem will react to that “Event”!

I don't know, this isn't one of the models we test with or recommend. I believe we have only tested AirLink RV50/RV50X or RV55/RV55X.
