Was wondering if anyone has experimented with interfacing with a Sierra wireless aircard for cell network connectivity?
Spitballing, So Chrysler uconnect head units have built in aircards they use for telematics, remote updates, remote unlock, in car WiFi, and 911 access.
Some features are subscription like WiFi , unlock and remote location lookup, however the telematics and remote updates are always on because the manufacturer wants them.
This says to me that the cell modem itself always has an active subscription.
I have an extra one on bench, It would be poetic to repurpose this active subscription for our own projects instead of their creepy one.
Card is a ar7552
