How does my car send notifications to my app when the car is not connected to WiFi

[harkrish]

I get notifications of car charging and stuff in places where I have not connected the car to Wifi, so is it based on bluetooth? I still get notified when I am fairly separated for bluetooth range, so I wonder how it does it!

It uses the car's telematics modem. It's essentially a free cell phone plan for your car that lasts 5 years from the original date of purchase (auto transfers if the car's ownership changes in that time). In the US it uses AT&T's network while in Canada it uses the Rogers network. 

 

Bluetooth is a short-range protocol, lol. Completely and utterly inappropriate for this use case.
