14 The write command specifies PDP context parameter values for a PDP context identified by <cid>, and the (local) context identification parameter. It also allows the TE to specify whether security protected transmission of ESM information is requested, because the PCO can include information that requires ciphering. There can be other reasons for the UE to use security protected transmission of ESM information, e.g. if the UE needs to transfer an APN. The number of PDP contexts that may be in a defined state at the same time is given by the range returned by the test command. Please refer to Chapter 6 for possible <err> values.

26 If the initial PDP context is supported, the context with <cid>=0 is automatically defined at startup, the parameters for <cid>=0 can be modified with AT+CGDCONT. If the initial PDP context is supported, AT+CGDCONT=0 resets context number 0 to its particular default settings.
