AT command for query pdp context status on ZTE AC2791( MDM6600 chip set)

[david preetham]

Hi,
On modem interface i am able to connect the service provider using AT
commands,
I have requirement to know the status of PDP (connected or disconnected).
Is their any AT commands to know the status? I don't have spec for AT
commands.
I tried to print AT commands supported AT&V no command helpful.

I tried AT+CREG, AT+CGACT,AT+CGATT this commands are not supported.
Is their anyway to know the pdp context status
Regards,
David
