1                Activation requirement 
<pdp_type/cid> Integer type; 
If <op> is 0, it is pdp_type. Otherwise, it is cid. 
pdp_type: It is the pdp_type wanted to activate.

cid:  It is a numeric parameter specifying a particular PDP context. Here it should 
be equal to the <cid> returned by the activation response. 
<apn>                                   It is the access point name which is mandatory for the activation requirement 
and should be omitted for the deactivation requirement. 
<user_name> It is the user name for access to the IP network which is mandatory for the 
activation  requirement  and  should  be  omitted  for  the  deactivation 
requirement. 
<pwd>                           It is the password for access to the IP network which is mandatory for the 
activation  requirement  and  should  be  omitted  for  the  deactivation

requirement and should be omitted for the deactivation requirement. 
1                NBIOT (Only NBIOT is supported currently) 
<sim_id>    It is the id of the SIM Card wanted to use which is optional for the activation 
requirement and should be omitted for the deactivation requirement. 
1                SIM Card 1 (Only SIM Card 1 is supported currently). 
<cid>  It is a numeric parameter specifying a particular PDP context. 
<type>           0                Result/URC for deactivation requirement 
1                Result/URC for activation requirement 
2                URC for passive deactivation
