Howto: Access wifi at Delhi airport 

Today, I am having an hour to kill at the new NewDelhi Airport. When I booted my laptop, my laptop detected two networks. But when I connected to either, internet connection didn’t happen by default.

Airtel’s network requires you to carry a mobile phone. When you start your browser it prompts you for a mobile number. The username and password are sent by SMS. You will need these login credentials to access the internet.

I’m done. I can kill the hour now. But I wonder if this would work for international passengers.
