Staying online in India is cheap and easy. India has some of the lowest mobile-data prices in the world, and you can choose between a travel eSIM or a local prepaid SIM.

Option 1: Travel eSIM (Easiest)

If your phone supports eSIM, you can buy an India data plan online before you fly and activate it the moment you land — no shop visit and no swapping physical cards. It's ideal for short trips. Most travel eSIMs are data-only, so you keep your home number for calls and banking codes.

Option 2: Local Prepaid SIM

Local carriers — Jio, Airtel and Vi — sell cheap, data-heavy prepaid packs and give you an Indian phone number. That number is handy for ride apps, deliveries and OTP verification, including IRCTC registration with an international number. This is the best value for longer stays.

Where to Buy

Airport counters are convenient but pricier; official carrier stores in the city are cheaper and just as quick. Buy from an official store rather than a random kiosk.

What You Need

Bring your passport, visa and a passport photo; some outlets also ask for a local address. Activation can take anywhere from a few minutes to a few hours.

Quick Tips

• Pick a data-heavy pack — data is remarkably cheap in India.
• Keep your home SIM active for banking OTPs.
• For eSIM, check your phone is unlocked and eSIM-compatible before you travel.

Bottom line: for a short trip a travel eSIM is simplest; for a longer stay a local Jio or Airtel SIM gives the best value and an Indian number.
