GPRS

When using the GPRS, it is recommended to implement a "keep alive" mechanism.
The G24-L memory resources should not be used as a buffer for the user, the user maintains its
own memory and flow control in its own application. The G24-L has finite limited resources such
as network related, SIM card and phone memory. In general the user should use a single resource
at a time. As an example, when G24-L GPRS network resources are in an active session, user
should not manually detach from the network or place a CSD call etc.
