Keep in mind however that the 4G SIM is not there for the driver's benefit, but for Nissan's. It collects extremely invasive telemetry that is then sold to data brokers and consumed by car insurers and government agencies, among others. This is why I won't drive a car that I own without first removing the onboard modem.
