> Before using the GPRS service (transmit data) several steps have to be run through: At first all necessary initialization commands must be executed. Next the module must be attached to the GPRS service. From that moment onwards the device is reachable by the network, but no data transmission is yet possible. Before activating the PDP context, network provider specific context parameters have to be defined. Afterwards the context can be activated and the module can enter the GPRS data mode. From now one data can be exchanged between module and network.
> The context deactivation and GPRS detach should be performed in the reverse order.
