India is one of those destinations where getting lost is part of the magic, but running out of internet in Delhi or on a night train to Rajasthan is another story. Getting an Indian tourist SIM means paperwork, passport copies, and sometimes waiting hours to activate it. An eSIM for India saves you all that hassle and connects you as soon as you land. In this guide, you'll see the coverage, operators, how many GB to take, and why an eSIM beats a local SIM.
Why an eSIM instead of a tourist SIM?
Because in India, buying a local SIM for tourists is one of the most cumbersome procedures: they ask for a passport, visa, photos, forms, and activation can take hours or even a day. An eSIM for India is installed before you fly and works as soon as you land, with no queues or paperwork.
The difference is enormous when you arrive at Delhi's Indira Gandhi airport at dawn after a long flight, and the last thing you want to do is fill out forms. With an eSIM, you open your phone, activate data, and you already have Google Maps to hail a taxi with a fixed fare, WhatsApp to notify your hotel, and a search engine for whatever comes up. Plus, you keep your Spanish number active on the other line to receive bank SMS messages. For an intense country like India, where you'll rely heavily on transportation and translation apps, having internet from minute one removes a lot of friction.
Operators and coverage in India
India has one of the best coverage-to-price ratios in the world, with massive 4G and 5G growing rapidly in major cities. The network reaches virtually all urban centers and most tourist routes, although in rural areas of the Himalayas or the Thar Desert, the signal becomes patchy.
The three major operators are Jio, Airtel, and Vi (Vodafone Idea). Jio and Airtel have the widest coverage and best speeds. An eSIM relies on the local network with the best signal, so you don't have to choose between operators: it automatically connects you to the one that works best in each part of the country.
| Area | Typical Coverage | Recommendation |
|---|---|---|
| Delhi, Mumbai, Bangalore | Excellent 4G / 5G | Everything: video, video calls, browsing |
| Golden Triangle Cities | Stable 4G | Maps, transportation apps, and social media |
| Rural / Himalayas / Thar | Patchy | Download offline maps and translations |
Useful tip: India uses mobile payments a lot (UPI, QR codes), but it usually requires an Indian bank account. As a tourist, your best bet is reliable data for transport and translation apps.
How many GB do you need for India
India keeps you glued to your phone: maps all the time, taxi apps, translation, endless photos. For a two-week trip through the Golden Triangle, estimate about 8-10 GB if you're a heavy user; for shorter trips or moderate use, 5 GB will be plenty. Adjust based on whether you make video calls.
- Short trip (5-7 days): 5 GB for maps, transport, messaging, and social media.
- Two weeks (Golden Triangle): 8-10 GB with daily use of apps and photos.
- Long stay or remote work: 15 GB or more, preferably with top-up available.

eSIM vs. roaming from your Spanish operator
India is well outside the European roaming zone, so your Spanish tariff does not apply. Traditional roaming here costs around €10-€20 per day, and for a two-week trip, that's a fortune compared to the cost of a local data plan via eSIM. Furthermore, many roaming packages come with daily limits that are quickly exhausted.
With an eSIM, you pay a fixed rate for the contracted GB and control the exact spending, without surprises when you return. If you're still debating between eSIM or roaming, in India the answer is clear: eSIM wins on price and convenience. And if you want the complete method to avoid overpaying, here's how to avoid roaming abroad.
How to activate your eSIM for India step-by-step
Installing an eSIM is quick and doesn't require opening your phone or looking for the SIM ejector tool. You set everything up from Spain with Wi-Fi and only activate it upon landing. The process takes approximately one minute.
- Purchase the eSIM and receive the QR by email instantly.
- With Wi-Fi at home, add the plan by scanning the QR in Settings.
- Keep your Spanish number as primary and label the new line "India".
- Upon landing in Delhi, Mumbai, or wherever you arrive, activate the eSIM data and its data roaming.
- You will see the local network (Jio, Airtel, or Vi) and you're good to go online.
If this is your first eSIM, follow the step-by-step guide on how to activate an eSIM. And first, check if your phone supports it with the guide to eSIM-compatible phones: almost all recent models are.
Tips for staying connected in India
India is chaotic in the best sense, and a good connection helps you tame that chaos. These tips will help you make the most of your eSIM between megacities, endless train rides, and remote villages.
- Install the eSIM at home: the QR needs Wi-Fi; get it ready before you fly.
- Download offline: maps of the Golden Triangle and Hindi/English translations in case you lose signal on trains or in rural areas.
- Use reliable transport apps: with data, you can order fixed-fare taxis and avoid price misunderstandings.
- Conserve battery: carry a power bank; heat and GPS use drain your phone quickly.
- Spanish support: with PuraSim, you can resolve any questions in your language, 24/7.
With these habits, your GBs last longer, and you avoid the classic predicament of running out of internet just when you need to reorient yourself in a crowded station. In India, being connected means being at ease.
Frequently Asked Questions
Does an eSIM avoid the paperwork of an Indian tourist SIM?
Yes, and that's its major strength. A tourist SIM in India requires a passport, visa, photos, and forms, with activation that can take hours. An eSIM is installed before you fly and works as soon as you land, without paperwork or waiting at the airport.
Which operator does the eSIM use in India?
The eSIM relies on the local network with the best signal, usually Jio or Airtel, which have the widest coverage and fastest speeds in the country, along with Vi (Vodafone Idea). You don't have to choose manually: it connects to the best available network in each area where you are.
How many GB do I need for two weeks in India?
For two weeks through the Golden Triangle with intensive use of maps, transport apps, and photos, estimate between 8 and 10 GB. If your usage is moderate or the trip is shorter, 5 GB is usually enough. Choose a plan with top-up if you plan to make video calls.
Is 5G available in India with an eSIM?
Yes, in major cities like Delhi, Mumbai, or Bangalore, 5G is widespread and growing rapidly. If your phone is 5G compatible and you are in an area with coverage, the eSIM will take advantage of that speed. In rural areas, you'll rely on 4G or patchy signal.
Do I keep my Spanish number in India?
Yes. The eSIM uses a separate line, so your Spanish number remains active in the other slot for receiving SMS and calls, such as your bank's code. You only activate the eSIM data and completely avoid expensive roaming from your regular plan.
Conclusion
India rewards the connected traveler: transport apps, maps, and translation are your best allies in a country as vibrant as it is intense. An eSIM saves you the cumbersome paperwork of a tourist SIM, connects you to Jio or Airtel as soon as you land, and frees you from expensive roaming. Get your eSIM for India ready before you fly and land in Delhi with internet from the very first minute.
