10.2. AT+CGDCONT Define PDP Context
AT+CGDCONT specifies PDP context parameters for a specific context <cid>. A special form of the write
command (AT+CGDCONT=<cid>) causes the values for context <cid> to become undefined. It is not
allowed to change the definition of an already activated context.
The AT+CGDCONT read command returns the current settings for each defined PDP context.
