You land at Indira Gandhi International in Delhi. You walk toward the SIM counter with your passport ready. The attendant asks for your Aadhaar. Aadhaar is India's biometric national ID — every Indian resident has one. Tourists don't. Without it, getting a local SIM in India is one of the most bureaucratically frustrating experiences in Asia.
There is one clean solution, one zone where even that solution doesn't work, and two apps you need to download before your plane boards.
The Decision Table: India Connectivity
| Your situation | Local SIM | Travel eSIM | Verdict |
|---|---|---|---|
| Delhi/Agra/Jaipur/Goa standard trip | Aadhaar required — hard for tourists | No Aadhaar, no queue | eSIM wins clearly |
| Visiting Ladakh or Leh | Local SIM required — eSIM doesn't work there | Doesn't work in Ladakh | Buy local SIM in Leh |
| Using UPI payments | Requires Indian bank account | Same limitation | Neither helps with UPI |
| Long-stay (30+ days) | Worth registration effort for cost | More expensive per GB | Local SIM better long-term |
| Arriving late at night | SIM counters may be closed | Pre-installed, instant on | eSIM essential |
The Aadhaar Problem and the App Ban
Local SIM registration requires Aadhaar, which tourists simply don't have. A travel eSIM doesn't use that registration process at all — you get instant connectivity the moment you land.
There's also a second problem: in January 2024, India's Department of Telecommunications had several foreign travel-eSIM apps removed from the Indian App Store and Play Store, including Airalo and Holafly, while it develops a licensing framework. The practical takeaway: install your travel eSIM from a provider's website using the QR code before you land, rather than relying on an app you may not be able to download inside India.
Coverage: Jio vs Airtel, and the Ladakh Exception
India has three competitive carriers: Jio, Airtel, and Vi. For tourists, the key choice is between Jio and Airtel.
In major metros including Delhi, Mumbai, Bengaluru, and Goa: both provide excellent 5G at 100–300 Mbps. For the Golden Triangle, Kerala backwaters, and rural Rajasthan: Jio has better national coverage, particularly in smaller towns and along highways.
The Ladakh exception — critical warning: For border-security reasons, India does not allow prepaid or non-local SIMs to operate in the Ladakh region — and that ban includes international travel eSIMs. Only an Indian postpaid SIM works there. If Ladakh is on your itinerary, buy a local SIM in Leh's market. Your eSIM works perfectly for the rest of India.
Situation 1: Golden Triangle with eSIM
A traveler arriving at IGI at 11pm finds the SIM counter understaffed. Their pre-installed India eSIM connects within 60 seconds of disabling Airplane Mode. Uber from the airport, Google Maps to the hotel, done. The traveler in the next queue is still waiting for the SIM desk to open at 6am.
Situation 2: Heading to Ladakh after Delhi
A traveler's international eSIM works perfectly across Delhi, Agra, and Jaipur. On the flight to Leh, they lose connectivity and it doesn't return. This is expected — not a provider failure. Buy a local SIM in Leh market for the Ladakh leg, then switch back to the eSIM for the return to Delhi.
3 Questions Before You Buy
1. Is your itinerary Ladakh-only or does it include Ladakh? If Ladakh is on your list — even as one stop — arrange a local Leh SIM separately. Your eSIM will not work there.
2. Have you installed the eSIM from a website (not an app)? Several major eSIM apps are unavailable in India's app stores. Install from a provider's website using QR code before you board.
3. Do you need UPI payments? India's digital payment system requires an Indian bank account — not available to tourists regardless of SIM type. Carry international cards and some cash.
Setup Before You Fly
- Purchase India eSIM — confirm it connects to Jio and/or Airtel
- Install via provider's website QR code at home (not an app — may be unavailable in India)
- Download offline Google Maps for every city on your itinerary
- Download Uber and link payment before departure
- On landing at IGI or CSIA: Settings, India eSIM, enable Data Roaming
FAQ
Why can't I download Airalo or Holafly in India?
In January 2024, India's DoT removed several foreign eSIM provider apps from Indian app stores while developing a licensing framework. Install your eSIM before arriving using your provider's website and QR code. No app required. The eSIM itself works normally once installed.
Does an international travel eSIM work in Ladakh?
No. India prohibits prepaid and non-local SIMs in the Ladakh region for border security reasons — this includes all international travel eSIMs. If your itinerary includes Ladakh or Leh, purchase a local SIM at a Leh market shop before reaching the restricted zone. Your eSIM works normally for the rest of India.
Can I use Google Pay or Paytm in India with a travel eSIM?
No — India's UPI payment system requires an Indian bank account linked to an Indian phone number. This is not available to tourists regardless of which SIM or eSIM they use. Carry international credit and debit cards, and use your eSIM data to locate ATMs and card-accepting restaurants.
