Your question: "Can I use the Spotify iOS SDK in India using a premium account in the USA without any proxy network?". Based on the fact that you are trying to create a streaming application, I think the question you intended to ask is: " Is it possible for users to transfer Spotify music in India?
My answer: I just read (parts) of the developer’s terms in the Spotify SDK. I noticed one thing:
Streams through the Spotify platform should be available only to Premium Spotify subscribers.
So, if I am right, it is only possible to play Spotify music, if your users have a Premium Spotify account, which is currently not available in India, everything is there. However, you can use the iOS SDK in India, but this eliminates the ability to broadcast (preview) the sound to users who are not premix.
