The “AT+CGDCONT” command can be used to specify 2 different PDP Contexts. However out of the 2 PDP Contexts the TR-900 supports only one PDP Context to be active at any point of time. Hence even by using the multiplexing option, it is not possible to make two GPRS connections at the same time.
Is it possible to make 2 GPRS Connections at same time using multiplexing?
