APN configuration on Android tablet

[sierrawireless]

Hi,

I am integrating Gobi3K modem of Qualcomm in my tablet.
I can use the Gobi3K modem to make a dial up connection in China. But if I try the same from the Android based tablet, I always get the DHCP error.

I feel that the APN and other settings necessary for a GSM network, need to be configured from the GUI. Could you please share the steps on how to configure APN settings for GSM network on my android tablet GUI ?
