Short answer: 5–10 GB covers most trips to India. The real argument for an eSIM here is not price — Indian data is famously cheap — it is that a tourist SIM involves forms, photos, a local address and an activation wait, while an eSIM is working before you clear customs.
The tourist SIM problem
Buying an Indian SIM as a visitor typically means a passport copy, a visa copy, a passport photograph, a local reference address and an activation delay that can run from a few hours to a day. Some arrivals halls sell tourist SIMs at a premium to shortcut this.
A travel eSIM skips the whole process. It roams onto an Indian network as a visitor: no forms, no wait, no local address.

How much data do you need?
- Two weeks, light use — 5 GB: maps, messaging, ride-hailing, train times.
- Normal trip with photos — 10 GB.
- Long stay or remote work — 20 GB or unlimited.
Hotel Wi-Fi ranges from excellent to theoretical. In smaller towns, your own mobile data will often be the better connection.
Coverage across India
Jio and Airtel between them cover the country extraordinarily well, including much of rural India, and 5G is widespread in the cities.
- Delhi, Mumbai, Bengaluru, Hyderabad, Chennai, Kolkata — dense 4G and broad 5G, including most metro systems.
- Rajasthan — Jaipur, Udaipur, Jodhpur, Jaisalmer — strong in the cities and on the highways; thinner in the desert beyond Jaisalmer.
- Goa and Kerala — good along the coast, the backwaters and the main roads; weaker in the Western Ghats.
- Himalayas — Manali, Leh, Rishikesh, Darjeeling — town coverage is decent; mountain roads and trekking routes are not. Ladakh in particular has long stretches with nothing, and some border areas restrict service.
- Long-distance trains — coverage follows the line and drops between towns. Download before boarding an overnight service.
Rural Indian coverage is better than most visitors expect, and mountain coverage is worse. Plan around the mountains, not the villages.
Setting it up
- Confirm eSIM support and that the handset is unlocked. Check your device
- Install at home on Wi-Fi with the line off.
- On landing, turn the line on with data roaming for that line only.
- Turn mobile data off on the home line.

India-specific notes
- Payment apps. India runs on UPI, which is generally tied to an Indian bank account and number. Visitors mostly use cards and cash; do not assume you can pay by QR everywhere.
- Ride-hailing and auto-rickshaws. Both work well in the cities and both need data. Booking through an app removes most of the fare negotiation.
- Verification codes. Indian services send SMS to Indian numbers. Bookings made in advance from home avoid most of that friction.
- Train and flight apps. Download tickets as PDFs rather than relying on loading them at the platform.
Frequently asked questions
Do travel eSIMs work in India?
Yes. They roam onto Indian networks as a visitor connection. Note that Indian eSIM regulations are stricter than most countries', so buy from a provider that explicitly lists India rather than assuming a global plan covers it.
Is an eSIM cheaper than an Indian tourist SIM?
Often not, on raw price — Indian domestic data is among the cheapest in the world. The eSIM advantage here is time and paperwork, not cost.
Can I get an Indian phone number with a travel eSIM?
No. Travel eSIMs are data-only and do not give you a local number. If you specifically need an Indian number for UPI or local verification, that requires a local SIM and the accompanying paperwork.
Is coverage good in Ladakh and the Himalayas?
Patchy. Towns have service; passes and trekking routes frequently do not, and some border regions restrict mobile service altogether. Carry offline maps and do not rely on being reachable.
How much data does a two-week trip need?
Around 10 GB for most travellers, or 5 GB if you lean on hotel Wi-Fi and use maps sparingly.
