VOC is connected to the vehicle's airbag and alarm systems. The vehicle has an integrated Global System for Mobile Communications (GSM) module that handles communication between the vehicle and the VOC customer service center.
Availability
VOC uses the Global Navigation Satellite System (GNSS) to locate the vehicle and its integrated GSM module to enable communication with the VOC customer service center and the VOC mobile app.
From the time that the remote key has been removed from the vehicle, VOC's functions remain available for 5 full days and subsequently once an hour for the following 17 days. After three weeks have elapsed, the system will remain switched off until the engine is started.
Warning
The system can only function in areas where there is adequate cellular network coverage.
Just as in the case of cell phones, atmospheric disturbances or areas with relatively few GSM transmitters can make it impossible for VOC to make a connection, for example, in rural areas.
Subscriptions
A free, limited-time trial subscription is initiated when the vehicle is purchased and VOC is activated. The subscription can be extended by contacting your Volvo retailer.
