Reliable mobile data makes travelling around India much easier. You can use it to navigate large cities, contact hotels, book transport, check train information, translate local languages and stay in touch through WhatsApp.
Whether you are visiting Delhi, Mumbai, Jaipur, Agra, Goa, Kerala, Bengaluru or the Himalayan regions, having your own internet connection is more practical than depending entirely on hotel or public WiFi.
Tourists can get mobile data in India through a travel eSIM, local prepaid SIM card, international roaming or WiFi. For most short-term international visitors, an eSIM is the easiest option because it can be purchased and installed before departure.
Quick answer: install your India eSIM before travelling, then enable it after arrival by selecting it for Mobile Data and turning on Data Roaming.
