So if im in civilasation (which i will get to eventually) i'm going to be wanting to withdraw money in India so i can continue with my travels. So a few questions (i'm with natwest by the way)

1) In a built up area is it easy to find somewhere to withdraw cash?
2) i have to tell my bank before i go right?
3) Is there anything i specifically need to arrange before using my card abroad

NB my card is one of those shitty solo cards
