Do you recommend using the Schwab card when visiting India? I'll be there for about a week for a wedding, but I'm curious if you recommend bringing cash at all (we're doing 4-5 days of touring before the wedding so probably some cash for snacks, gifts and such).

Sorry for sounding noob, but this is my first time visiting India, and for reference when I visit China/Japan/Taiwan/Hong Kong my strategy is pretty much to land with minimal cash (like $20 USD equiv, usually some change from my last trip) and to get the rest of my cash I need via ATM.

Is it reliable to use ATMs in India? Also are there specific banks I should stick to when looking for ATMs to withdraw from? I'll have a backup card or two just in case things go south although I'm really hoping my Schwab card is the one I rely on as fees are no concern with that card.
