Anybody know how to use Airtel 3G using Huawei E173 in Kerala

Airtel launched 3g service in Kerala on 28th July. Airtel didnt win the 3G auction in Kerala, but they are providing 3g service by sharing 3g spectrum with Idea. I activated Airtel 3g on my mobile, but I have to select Idea 3g network to access it. Its working superbly. Now I want to use this on my Huawei E173 3G usb modem. I dont know how to configure it. Can anybody please how to use Airtel 3G using E173? Its urgent. So please help me

1)Install mobile partner
2)Create airtel/idea profile in it ( APN for idea is internet , APN for airtel is airtelgprs.com)
3)On mobile partner Click tools>options>network>registration mode> select manual search and register > click refresh> select idea> click register.
4)Now connect with idea or airtel profile
I’m not sure whether this will help or not.....

Hi, i use the same thing.
Just activate 3G on airtel and use that sim.
i only find the flexi @ 149 Rs. for 2GB data worth the price
The access point is the same.
