Option 1: An Indian tourist SIM
The big networks are Jio, Airtel and Vi. Tourist SIMs are sold at counters in major international airports and at operators’ own stores.
- Bring: your passport, visa or e-Visa, and a passport photo; an Indian address (your hotel) and sometimes a local reference.
- Activation: usually within a few hours after verification.
- Data plans are inexpensive by global standards; pick one that covers your whole stay.
Option 2: An international eSIM
Global eSIM apps sell India data plans you install before you fly. They’re convenient and work on arrival, but usually cost more per GB and may not include an Indian phone number, which some apps (cabs, UPI, train bookings) need for OTPs.
Option 3: Roaming
Simple, but check your home carrier’s India rates. Some US, UK and Gulf plans now include India.
For NRIs
Keep your Indian number active if you can: banks, Aadhaar-linked services and UPI depend on it. Many NRIs use a low-cost long-validity plan.
Tips
- Ask the shop to test data and calls before you leave.
- Coverage is strong in cities and along highways, weaker in high mountains and remote islands.
- Wi-Fi is common in hotels and cafés but can be slow.
