In 2026, you should not be buying physical SIMs at the airport. You should use an eSIM. But you have to choose between convenience and full functionality.

Airtel vs. Jio: The Coverage Reality

  • Airtel: Go to an official corporate store, not a franchise. Holds the monopoly on rural coverage, mountains (Ladakh, Himachal), and national parks.
  • Jio: Faster in major metros (Mumbai, Bangalore) but drops off significantly off the grid.
