I'm getting a new car soon and one of the cool features is the ability to remote control/link the car from a phone app. However, this requires a sim to be installed in the car. I don't envisage much data usage, other than some commands to turn the lights on and off, opening the boot, etc. until the novelty wears off. Is just a standard prepay plan the way to go, or are there more appropriate options for this situation?
