If you’re planning a trip to India, having reliable mobile internet makes traveling much easier. You’ll use it for Google Maps, hotel bookings, ride-hailing apps, train schedules, WhatsApp and keeping in touch with family and friends.
Today, travelers can choose between a travel eSIM, a local prepaid SIM card, international roaming or public WiFi. While local SIM cards are still available, many international visitors now prefer an eSIM because it can be installed before departure and activated immediately after landing.
