The PDP type must match exactly.
The PDP addresses are considered to match if they are identical or if either or both addresses are
unspecified. For example, a PPP NCP request specifying PDP type = IP and no PDP address would cause
the MT to search through the specified context definitions for one with PDP type = IP and any PDP
address.
The context shall be activated using the matched value for PDP type and a static PDP
address if available, together with the other information found in the PDP context definition.
If a static PDP address is not available then a dynamic address is requested.
If no <cid> is given or if there is no matching context definition, the MT shall attempt to
activate the context with whatever information is available to the MT. The other context
parameters shall be set to their default values.
If the activation is successful, data transfer may proceed.
After data transfer is complete, and the layer 2 protocol termination procedure has
completed successfully, the V.25ter command state is re-entered and the MT returns the
final result code OK.
In the event of an erroneous termination or a failure to start up, the V.25ter command state
is re-entered and the MT returns the final result code NO CARRIER or, if enabled, +CME
ERROR. Attach, activate and other errors may be reported.

: a string parameter that indicates the layer 2 protocol to be used
between the TE and MT
NULL
none, for PDP type OSP:IHOSS (Obsolete)
PPP Point-to-point protocol for a PDP such as IP

M-xxxx manufacturer-specific protocol (xxxx is an alphanumeric
string)
If the value is omitted, the layer 2 protocol is unspecified. Other values
are reserved and will result in an ERROR response.
<cid>
: a numeric parameter which specifies a particular PDP context
definition (see the +CGDCONT and +CGDSCONT commands).
1.32.13. Show PDP address +CGPADDR
The execution command returns a list of PDP addresses for the specified context identifiers.
The test command returns a list of defined <cid>s
