GPRS stands for General Packet Radio Service, in the most simplest of terms it refers to the Syrus’ connection to the internet via the SIM card.  GPRS is GSM based, this means that it is an evolution from GSM technology, and as the name implies, it uses Packet Switching technology to transmit data.

When we talk about Syrus and mention GPRS we refer to having the communication channel available for the device to speak to the server/platform.  If GPRS is down, this means that there is no internet connectivity on the device and this can happen if cell phone carriers do not provision the SIM correctly.
