ATTENTION! Some GSM operators may disconnect the device from an
active data link if the device doesn’t send any data for a very long time, even if
active data link timeout is set to maximum value. The amount of time that an
operator keeps the link open depends solely on the operator. For example, if
active data link timeout is set to maximum, 259200 seconds (72 hours), and the
device sends data to server every 86400 seconds (24 hours), the operator might
disconnect the link earlier and the device will have to connect to the server anew.
This may cost extra, depending on the operator GPRS data charge. It is strongly
recommended, when using active data link timeout, that data sending to the
server should not be very rare (24 hours or more). If data sending is more
frequent, then the operator will not disconnect the device form the server.
