The Indian government is making it easier for foreign travelers visiting the country by providing a pre-activated SIM card on arrival. The SIM card is issued by state-run BSNL, and comes with 50MB of data along with a ?50 credit (90 cents) for making calls. You can top up the data and get additional balance for calling by recharging online.
The SIM card comes with a kit that contains maps, brochures for popular tourism destinations, along with contact information for a 24-hour tourist helpline number that's available in 12 languages, including Russian, German, and Japanese.
All you need to do to pick up your SIM card is show a copy of your e-visa at the immigration counter.
