A sim card will give the option to have “talk-time” to call within or outside the country. You can also add “data” to your India sim card, so that you can have internet connection on your mobile. It sounds easy, but we’ve experienced that the Internet Service in North India is not reliable at all times.
To acquire a phone or a sim card in India you need to provide a copy of your passport and visa and a passport photo to the retail shop where you are buying it from. Sim cards for foreigners are valid for a 3-month period only.
