Best eSIM for Indian Travelers Going Abroad

Planning an international trip is exciting, but figuring out your phone situation can be a real headache. We’ve all faced the choice: either risk a shocking roaming bill from your Indian provider, or waste precious vacation time hunting for a local SIM card at the airport. But what if there was a smarter, cheaper way to get connected the moment you land?

Meet the eSIM, a digital SIM card that is already built into most modern smartphones, including many popular models in India. Instead of swapping a tiny piece of plastic, you simply activate a data plan by scanning a QR code you receive via email. This means you can buy and set up your prepaid eSIM for tourists from India before you even leave home.

So, how does an eSIM work for international travel? It primarily gives you affordable mobile data, which is exactly what you need for using Google Maps, booking an Uber, or making calls on WhatsApp. It’s an easy upgrade from the old way:

• Physical SIM: You buy it at your destination, have to physically insert it, and risk losing your home SIM.
• eSIM: You buy it online before you go, it's digital so it can't be lost, and activates with a simple scan.

Is Your Indian Phone eSIM-Ready? A 30-Second Check

Before you start browsing for plans, the first step is to confirm your phone can actually use an eSIM. Thankfully, there’s a quick trick that works on most smartphones. Just open your phone’s dial pad as if you were making a call and type in *#06#. A box will pop up with your phone's identification numbers. If you see a number labelled “EID” in this list, congratulations – your phone is eSIM compatible!

As a general rule, most premium phones bought in India over the last few years have this feature built-in. This includes popular models like:

• Apple: iPhone XR, XS, and all newer models (iPhone 11, 12, 13, 14, 15 series)
• Samsung: Galaxy S20, Note 20, Flip, Fold, and all newer flagship models
• Google: Pixel 3 and all newer Pixel phones

Another way to double-check is by looking in your phone’s settings. For iPhone users, go to Settings > Mobile Data and see if you have an “Add eSIM” option. On Android, it's usually under Settings > Network & Internet > SIMs, where you’ll find a “+” sign or an option to “Add eSIM” or “Download a SIM instead?”. If you see this, you’re all set for setting up an eSIM before you travel abroad.

How to Activate an International eSIM in 3 Simple Steps

Now that you know your phone is eSIM-ready, you’re just a few taps away from having affordable data for your trip. Setting up an international eSIM before traveling abroad is surprisingly straightforward. The key is understanding the difference between installing the eSIM (which you do at home) and activating it (which you do only after you land).

This approach prevents any confusion and ensures you don't accidentally start your data plan early. The entire process is designed to be done in advance, giving you peace of mind.

Here’s the simple, three-step method that works for almost every provider:

1. Buy: Choose Your Plan Online First, visit Matrix Cellular’s official website and choose an international eSIM plan designed specifically for Indian travelers. Pick your destination-whether it's a single country like the USA or a whole region like Europe-and buy the data plan that fits your trip length. You will receive a QR code in your email almost instantly.
2. Install: Scan the QR Code at Home While you are still in India with a good Wi-Fi connection, open your phone's settings and find the "Add eSIM" option. Your phone will ask you to scan the QR code from your email. This installs the digital SIM onto your device but does not start the plan. Just keep it turned off in your settings for now.
3. Activate: Switch It On After You Land Once you land at your destination, simply go back into your phone's mobile data settings. Turn OFF your primary Indian SIM for data (to avoid roaming charges!) and turn ON your newly installed eSIM. Your phone will connect to the local network within a minute, giving you instant internet access.

Which eSIM Provider is Best for Your Trip?

For Indian travelers going abroad, the best eSIM provider is one that understands your needs, offers prepaid international data plans you can activate before you leave, and gives you reliable connectivity the moment you land — all without expensive roaming charges.

Matrix eSIM checks all those boxes. It’s designed with Indian travelers in mind, offering:

• Prepaid international plans that are easy to buy from home
• Instant QR-code activation before departure
• Wide destination coverage (Europe, USA, Asia, Middle East, and more)
• Compatibility with modern iPhone and Android phones
• Dual SIM support, letting you keep your Indian number active for calls and OTPs while using Matrix eSIM data abroad

With Matrix eSIM, you skip long airport SIM queues, avoid surprise roaming bills, and stay connected seamlessly throughout your trip. That makes it a smart and reliable choice for travelers from India heading overseas.

Finding eSIM Plans for Popular Destinations: Europe, USA, and Thailand

The value of an eSIM truly shines when you look at the cost. A standard 10-day international roaming pack for the USA from a major Indian provider can easily cost you ₹3,000 or more. In sharp contrast, you can find international eSIM plans for Indians that give you plenty of data for the same duration for under ₹1,500. You are essentially getting the same essential connectivity—for maps, taxis, and messaging—for less than half the price, without touching your primary Indian SIM card.

This incredible value isn't just for long-haul flights. For popular Southeast Asian getaways like Thailand, the savings are even more striking, offering some of the cheapest global eSIM data plans available. It’s common to find a plan for a one-week trip for under ₹800. That’s more than enough data to use Google Maps to navigate Bangkok's streets, post all your beach photos, and stay in touch on WhatsApp without a single worry about a shocking bill when you get home.

For those planning a multi-country European adventure, the convenience is just as important as the cost. A single eSIM for Europe from India means you buy one plan that works seamlessly as you travel from Paris to Rome to Berlin, a massive upgrade from hunting for SIM cards in every new country. The best part is the transparency; you can visit provider websites right now, enter your destinations, and see the exact cost before spending a single rupee. This puts you in complete control.

Can I Still Use My Indian Number for Calls and OTPs Abroad?

One of the best features of using an eSIM is that you don't have to give up your Indian number. Your phone essentially becomes a dual-SIM device, allowing you to use both your Indian SIM (for receiving calls and texts) and your new travel eSIM (for data) at the same time. This is incredibly useful for getting important SMS messages from your bank, like one-time passwords (OTPs), or for letting family reach you on your regular number in an emergency, all while you browse and navigate using your affordable eSIM data.

Getting this two-line system to work is surprisingly simple. Once your travel eSIM is installed, dive into your phone’s Settings and look for the ‘Mobile Data’ or ‘Cellular’ menu. You’ll see both your lines listed, often as ‘Primary’ (your Indian SIM) and ‘Secondary’ or ‘Travel’ (your new eSIM). The single most important step is to select your travel eSIM as the default line for Mobile Data. This tells your phone to use your cheap, prepaid travel plan for all internet-based apps like Google Maps, WhatsApp, and Instagram.

Finally, to guarantee you avoid a monster bill from your Indian provider, there's one crucial safety switch to flip. In that same settings menu, tap on your Primary (Indian) SIM and make absolutely sure that the toggle for ‘Data Roaming’ is turned OFF. This is your foolproof way to prevent your home SIM from connecting to data networks abroad. With this quick setup, you get the best of both worlds: cheap, fast internet on your eSIM and the peace of mind that your Indian number is active for essentials without racking up any charges.
