We are currently staying in India, but neither of our phones work, which is annoying when trying to hire taxis, for instance, or meet up with people. Purchasing a phone/sim will take 7-10 days to go through so we can't do it.
In the US there are usually pay phones in train stations or street corners but I haven't seen any here.
What's the best way to get/borrow/use a phone? Is there a convention in India that I don't know about? Ask random people on the street? Can you pay the people at the mobile phone recharge shops to use one of theirs?
