Hello, anybody ever deal with VPN networking using SIM900 or other GPRS/3G module? I am confused as to what AT command to use in order to select the VPN and enter username and password. I looked up in SIM900 AT command manual, but nothing specify VPN. Closest I can find regarding username and password would be setting APN.

Any insights are welcome. Thanks mate!
 

I think that you will need a separate processor running software that implements the VPN protocol that you need.
 

I think you are confusing VPN network and parameters used to access the VPN network...In order to access the VPN network, three parameters are mandatory: APN, USERNAME & PASSWORD..

There is nothing called VPN parameter to be selected in the SIM900 module..
