Default OPO Network Supported in India?

I know that the international model is supported in India. (Airtel and Vodafone)

But I'm thinking of importing this phone from China. They have a different kind of network some TD-WCDMA which is not supported in India. Will the Chinese model work in Indian 3G? I've asked around the OPO forums and nobody seems to know. I've messaged their support team but they haven't replied. Any ideas about this?
