In short: For a 2-week trip to India, a 15 to 20 GB India eSIM with 30-day validity will be more than enough for navigation, WhatsApp, and bookings. You install it at home by scanning a QR code, land with internet, no roaming, and no local SIM paperwork. Simple and without surprises.
India is one of those unforgettable trips. In fifteen days, you can go from the Taj Mahal in Agra to the palaces of Rajasthan, from the beaches of Goa to the temples of Tamil Nadu, or lose yourself amidst the smoke and chants of the ghats in Varanasi. It's chaos, color, and noise in equal parts, and to navigate all of it, your phone is your best ally. The question almost everyone has before leaving is the same: how to get data as soon as you land without complications. The short answer is an eSIM for India.
The good part: India boasts one of the fastest and cheapest mobile data networks on the planet. The inconvenient part: getting a local SIM as a foreign tourist can turn into an odyssey of photocopies, forms, and waiting. That's why more and more travelers are resolving it before they leave. Here we tell you how much data you need, where there is good coverage, how to install it, and the mistakes almost no one warns you that you will make.
Why an eSIM is the best option to connect in India
Buying a prepaid Indian SIM as a foreigner has never been quick. The country applies a mandatory registration known as KYC (identity verification) for any mobile line, and the process becomes even more complicated with tourists.
- You need to present your passport, visa, and sometimes a passport-sized photo.
- Activation is not always immediate: it can take from several hours to a couple of days.
- Some small shops do not want hassles with foreign documentation and directly deny it to you.
- You have to insert the physical SIM and manually configure the APN.
With an international eSIM, all that disappears. You buy it online, receive a QR code by email, scan it, and the profile is saved on your phone. When you land in Delhi, Mumbai, or Bangalore, you activate the data and that's it: internet from minute one, without going to any shop or filling out a single piece of paper. If you've never done it before, our guide on how to install an eSIM step-by-step will show you in detail, and if you're still debating between this technology and your carrier's plan, this comparison of eSIM vs. roaming clarifies it in five minutes.
The other big advantage is your wallet. Activating your company's roaming in India can exceed several euros a day and eat up your budget without you realizing it. A destination eSIM costs a fraction of that. We don't give exact figures because prices change, but the difference compared to traditional roaming is enormous; always check the current rate before deciding.
How many GB do you need for 15 days in India?
This is the million-dollar question and the answer depends on how you travel. Many mid-range and high-end hotels have decent Wi-Fi, but budget guesthouses, night trains, and rural areas have limited or no Wi-Fi at all. If you visit villages, national parks, or mountain routes, your eSIM will be your only connection. To get a realistic idea, this table summarizes typical consumption over two weeks.
| Traveler profile | GB for 15 days | What that usage includes |
|---|---|---|
| Basic | 8-10 GB | Maps, WhatsApp, email, and occasional browsing with hotel Wi-Fi support |
| Moderate (most common) | 15-20 GB | Social media, uploading photos, daily browsing, and minimal Wi-Fi support |
| Intensive | 25 GB or more | Video calls, remote work, streaming, and many hours away from Wi-Fi |
For most two-week travelers, the sweet spot is between 15 and 20 GB. With that, you'll be comfortable without rationing every megabyte. If you're someone who downloads offline maps and uses hotel Wi-Fi at night, 10 GB might be enough. And if you work remotely or make many video calls, go straight for 25 GB or a generous data plan. If you want to fine-tune the calculation according to your habits, check out our guide on how much data you need for travel.
A useful note: always choose a generous validity period. A 30-day plan for a 15-day trip gives you leeway if you install it early, if your flight is delayed, or if you end up extending your stay by a few days. Paying for a longer validity than you think you need usually pays off in peace of mind.
eSIM plans for India: how to choose
At PuraSIM, you'll find eSIM plans for India designed for different durations and budgets. The idea is simple: check how many days you'll be there, estimate your consumption with the table above, and choose the plan that covers both with a little buffer. This reference helps you get oriented.
| Profile | Indicative data | Recommended validity | Ideal for |
|---|---|---|---|
| Short getaway | 8 GB | 15 days | Those who frequently use Wi-Fi and consume little outside the hotel |
| Active tourist | 15-20 GB | 30 days | The average 2-week traveler who wants to avoid stress |
| Intensive use | 25 GB or more | 30 days | Digital nomads and those who make daily video calls |
Before paying, check two things: that your phone is eSIM compatible (most iPhones from XS onwards and mid-to-high-end Androids are) and that it is unlocked. Without these two requirements, no eSIM will work, regardless of the carrier. If you are combining India with other destinations in the region, such as Nepal or Sri Lanka, a regional plan might be more cost-effective than one for a single country; you can check the options for eSIM for Nepal and decide what works best for you.
eSIM Coverage by Region in India
India has surprisingly good coverage for its size, supported by carriers like Jio and Airtel, which have deployed widespread 4G across the country and even 5G in major cities. Still, there are nuances depending on where you go.
- Delhi and metropolitan area: excellent 4G/5G coverage. Even the metro has signal in stations.
- Rajasthan (Jaipur, Jodhpur, Udaipur, Jaisalmer): very good in cities. In the middle of the Thar Desert, there may be stretches without signal.
- Mumbai and Goa: outstanding coverage. Goa's beaches usually have stable signal.
- Bangalore and Chennai: tech cities with first-rate 4G/5G infrastructure.
- Kerala (backwaters, Munnar): good in cities; in the backwaters' canals, the signal can come and go.
- Himachal Pradesh and Ladakh: the weakest. In high mountains, signal is limited; in Manali or Leh, there is coverage, but it can be unstable.
- Varanasi: good in the city and on the Ganges ghats.
The general rule: in cities and classic tourist routes, you'll be fine; in remote mountain areas or national parks, prepare for stretches without data and download important things beforehand.
How to install and activate your eSIM for India
The process is easier than it seems and takes less than five minutes. Ideally, do it with your phone at home, with Wi-Fi and without rushing, a day before your flight.
- Buy your eSIM at least 24 hours in advance.
- Receive the QR code by email (and in your client area).
- Install it: On iPhone, Settings → Cellular Data → Add eSIM → Scan QR Code. On Android, the path is similar within Connections or Networks.
- Give it a recognizable name, like "India," so you don't get confused with your lines.
- Upon landing, activate the eSIM as the data line and turn on data roaming for that eSIM (this is normal and necessary; you won't be charged roaming: it's how the eSIM connects to the local network).
- Deactivate the data for your Spanish SIM so your phone doesn't accidentally use it.
That point about roaming confuses many people, so if you want to understand what it is and why you need to activate it, we explain it in what is data roaming. An extra tip: save the email with the QR and take a screenshot. If you have to reinstall the profile at your destination, you'll be glad you did.
What almost no one tells you about using your phone in India
Here are the tricks and warnings you won't find in most guides and that make the difference between a connected trip without hitches and one full of small frustrations.
The Indian OTP: your biggest headache
Many services in India (ordering an Uber or an Ola, paying with some apps, accessing certain Wi-Fis) ask for an OTP code via SMS to an Indian number. Your data eSIM usually doesn't come with a local number to receive these SMS. The practical solution: use your home carrier's app to receive SMS if you have occasional voice roaming, pay cash or with card when you can, and for transport, rely on Uber (which usually accepts verification by email or WhatsApp). Knowing this beforehand will save you more than one tight spot at the airport entrance.
Public Wi-Fi is a sieve
Stations, airports, and cafes offer free Wi-Fi, but many of these networks are open and not very secure. Precisely for this reason, having your own data with the eSIM provides a layer of protection: you don't depend on external networks to check your bank or enter a password. If you usually connect to public Wi-Fi, also consider using a VPN to encrypt your traffic.
Download EVERYTHING offline before leaving the hotel
Google Maps offline for each city, Google Translate with the Hindi pack downloaded, your train tickets, and your reservations in PDF. In India, the signal disappears at the most inopportune moment (an alley in Old Delhi, a train between states), and having the essentials saved on your phone saves you. Plus, you save data: to make the most of your plan, here are tricks to save data with your eSIM.
Be careful with video app consumption
Reels, YouTube, and TikTok devour gigabytes at a brutal speed, especially with auto-play enabled. Lower the video quality to 480p in settings and disable auto-play. With that simple change, 15 GB performs like 25 GB.
Carry a power bank no matter what
Using data, maps, and the camera all the time drains the battery, and on long journeys or in rural areas, there isn't always an outlet handy. A charged external battery is as important as the eSIM itself. Having internet is of little use if your phone is off.
eSIM, local SIM, or roaming: quick comparison
To see it at a glance, here's how each option stands for a two-week trip to India.
| Option | Ease | Relative cost | Paperwork |
|---|---|---|---|
| International eSIM | Very high: installed before travel | Economical | None |
| Local Indian SIM | Low: requires store visit and identity verification | Very cheap for data, but with procedures | Passport, visa, and waiting |
| Carrier roaming | High: no configuration needed | Can be expensive; check your rate | None |
For the average two-week traveler, the eSIM wins for convenience and lack of bureaucracy; the local SIM only pays off if you stay a long time and don't mind losing a morning on paperwork.
Frequently asked questions about eSIM for India
How many GB do I need for 2 weeks in India?
For 15 days with moderate use, between 15 and 20 GB is the most balanced. India has good 4G coverage in cities and tourist areas, so you'll consume data normally. If you rely heavily on hotel Wi-Fi, 8-10 GB might be enough; if you make video calls or telework, go for 25 GB.
Does the eSIM work in Delhi, Mumbai, Goa, and Rajasthan?
Yes. Coverage is excellent in Delhi, Mumbai, Bangalore, Chennai, Goa, and cities in Rajasthan such as Jaipur or Jodhpur. In very remote rural areas, in the Thar Desert or in the high Himalayas, the signal may be weaker or intermittent.
Do I need to register the eSIM or complete any paperwork in India?
No. International eSIMs do not require the KYC registration or identity verification that local Indian SIMs do. They work from the first moment you activate data upon landing, without a passport, without forms, and without waiting.
Is the internet speed good in India?
India has one of the most extensive 4G networks in the world and 5G in several large cities. In urban areas, you'll have plenty of speed for maps, social media, and video calls. In rural or mountain areas, the speed might drop, but it's usually still sufficient for basic needs.
Can I use Google Maps and WhatsApp with the eSIM?
Yes, without a problem. Both apps work normally. For Maps, download offline maps of the cities you're going to visit, and you'll save data and have navigation even if you lose signal. WhatsApp works perfectly for chatting and making voice calls over the internet.
Can I receive calls and SMS on my Spanish number?
Most destination eSIMs are data-only, so they don't come with an Indian number or handle conventional calls. To talk, use WhatsApp, Telegram, or any voice-over-data app. If you need your Spanish number active for occasional SMS, you can keep your SIM in your phone with data deactivated and use it only for that.
When should I install the eSIM, before or upon arrival?
Install it at home with Wi-Fi at least one day before your flight. Installation downloads the profile, and doing it with a stable connection prevents errors. However, do not activate data until you land in India: the plan's validity usually starts counting from the first use, not from installation.
India is equally captivating, exhausting, and wonderful, and having your connection sorted before you leave takes away the one headache you can avoid. If you want to compare carriers before deciding, our guide to the best eSIM for India will be helpful. Prepare your phone, download your maps, and enjoy: land with internet, no roaming, and no stress.
