Volvo On Call is fully available for 5 full days. For days 6-21, services such as, for example, remote control immobiliser and stolen vehicle tracking are initiated via a Volvo On Call service centre. After 22 full days, the system is disconnected to save the battery and is fully available again as soon as the car is startedAvailability of the functions may vary..
The system's services only work in areas where Volvo On Call partners have mobile coverage and on markets where Volvo On Call is available.
Just as with mobile phones, atmospheric disturbances or sparse transmitter coverage may lead to connection being impossible, e.g. in sparsely populated areas.
