If no custom settings have been made, an inactivity alarm is sent out if a GPS device has not been in contact with PosifonCare for three hours. An inactivity alarm can be due to various reasons, the main reasons being that the device is discharged or switched off, or that the device has no mobile coverage and therefore cannot pass on its information to the system. Other less common reasons may be that the device has broken down, for example due to water damage, or that it has stopped working for some other unknown reason. Please contact our support for troubleshooting.
