If you’re traveling to India, you’ll need reliable mobile internet for Google Maps, hotel bookings, ride-hailing apps, train schedules, WhatsApp and staying connected throughout your trip.
The two most popular options are buying a local prepaid SIM card after arrival or installing a travel eSIM before departure. Both provide internet access, but they offer very different travel experiences.
