I just ordered a new Nissan leaf for delivery in January 2021. The car will be built in UK and will be delivered in Scandinavia. For this cold climate here, it will be very good if the heater would run before I go to the car. So, I am wondering, how does the nissan connect communicate with my phone application? Does it use wifi, or does the car has a 2G/3G/4G simcard which communicates with the Nissan servers and later with my phone application? So, basically, what is the method of communication for the car?
I hope it is not through wifi, because if it is wifi, my car will not be able to communicate with my home wifi.
