Imagine this: You land in a new country, and instead of looking for a store to buy a SIM card, you tap a few buttons on your phone, and you’re connected to the local network. It would be nice, right?
This isn’t a dream - it’s real, and it’s called eSIM technology.
An eSIM is a digital SIM card that’s already in your phone, waiting to be activated. No tiny plastic cards, no poking your phone with a paperclip. It’s all digital and can be set up to stay connected wherever you go easily by tapping or scanning a code. It’s a traveler's best friend, making it easy to stay connected wherever you go.
But how does it work?
In this guide, we’ll walk you through the easy steps to use international eSIMs while you’re traveling. We’ll cover how to set it up on iPhones and Androids and share tips for using eSIMs abroad. Whether you’re a frequent traveler or just planning your next trip, this guide will help you stay connected the simple way.
What is an eSIM?
An eSIM is like a regular SIM card but without the plastic. It's a small chip inside your phone that helps it connect to your mobile network.
Unlike a regular SIM, you don’t have to insert an eSIM - it's already built into your phone!
How Does an eSIM work?
Activating an eSIM is easy. Instead of swapping out physical cards, you can just scan a code or enter some information into your phone. This tells your phone which network to connect to and your phone number.
It’s especially handy for people who travel a lot like us because you can switch to a local network without needing a new SIM card.
Are eSIMs Better Than Physical SIM Cards?
Both have their good points - it really depends on what you need!
eSIMs are great for making things simple and easy, especially when you’re traveling. You won’t lose it and can switch networks without needing a new card. But physical SIM cards are good, too, because you can move them from one phone to another. So, if your phone’s battery dies, you can use your SIM on a different phone.
We personally travel a lot, so we prefer avoiding the switch as we might lose our SIM card from back home, and we also prefer to get internet as soon as we land, but it's really up to you what works best for you.
Now that we have a clear idea of what an eSIM is, its benefits, and why it's a great tool for us as travelers, let's see how you can activate one both on iPhone (iOS) and Android phones.
As there are many eSIM providers out there, we will use Holafly as it's one of our go-to eSIM options during our travels.

How to Use eSIMs on Android
Which Android Phones Support eSIMs?
Many Android phones, like some of the Samsung Galaxy and Google Pixel models, support eSIMs. But because Android is an open-source system and lets phone makers and mobile carriers make their own changes, whether your Android phone can use an eSIM might depend on the model, where it was made, and your carrier.
The easiest way to check is to ask the company that made your device, the place where you bought it, or your carrier.
You can also check your phone’s settings to see if it can use an eSIM. Here's how:
Checking if a Samsung device supports eSIM:
- Go to your phone’s Settings and then Connections.
- Tap SIM Card Manager.
- If you see Add eSIM, your phone can use eSIM.
Checking if a Google Pixel device supports eSIM:
- Go to Settings and then Network & Internet.
- Tap eSIM Cards.
- If you see Download a SIM instead? under Connect to a Mobile Network, your phone can use eSIM.
Checking Other Android Phones:
- Open Settings and tap About Phone.
- Tap Show EID.
- If you see a number next to EID, your phone can use eSIM.
How Many eSIMs Can Be Used on Android?
Android phones can store multiple eSIMs (generally five to seven eSIM profiles), but similar to iPhones, they can only use one at a time.
Some Android models also support the Dual SIM Dual Standby (DSDS), allowing you to simultaneously use two numbers, one through a physical SIM and the other through an eSIM.
How To Set Up an eSIM on Android
Similarly to iPhone devices, once you've purchased your eSIM plan from an eSIM provider like Holafly, you can select one of the two methods to install your eSIM on Android:
Method 1: Using a QR Code
- Go to Settings and tap on Network & Internet.
- Tap on Mobile Network.
- Tap Download a SIM or eSIM Manager, depending on your device.
- Use your phone to scan your QR code, which you'll get from your carrier.
- Follow the prompts on your screen to complete the setup.
Method 2: Using an Activation Code (Manual Setup)
- Navigate to Settings and select Network & Internet.
- Tap on Mobile Network.
- Select Download a SIM or eSIM Manager, depending on your device.
- Instead of scanning a QR code, select Enter details manually.
- Input the information provided by your carrier and follow the on-screen instructions to finish the setup.
And voila! Your eSIM is set up and ready to keep you connected on your Android device.

What Are The Benefits of Using an eSIM for Travelers?
Using an eSIM while traveling can offer many benefits for travelers. Here are a few reasons why you should consider using an eSIM on your next trip:
- International Compatibility: With an eSIM, you can travel internationally with your iPhone or Android phone and enjoy greater security, flexibility, and reduced costs. It's like having a global passport on your mobile device!
- Switch Plans Easily: Depending on the country, you can conveniently switch between different calling or data plans, giving you the power to find the option that suits your needs best.

BONUS: 6 Tips for Using an eSIM While Traveling
If you're a digital nomad, a frequent traveler, or someone who loves exploring new places, then an eSIM (electronic SIM) is your new best friend. Gone are the days of worrying about switching physical SIM cards when traveling to different countries. With an eSIM, you can easily and conveniently switch between plans and stay connected wherever you go.
But how exactly can you use an eSIM while traveling? Here are 5 tips to help you make the most out of this amazing technology on your iPhone and Android devices:
1. Know Your Device
First and foremost, make sure your device supports eSIM functionality. Currently, iPhones from the XS and newer models support dual SIM (eSIM + physical SIM), while Android devices such as Google Pixel 4 and newer models also have this feature.
2. Purchase an eSIM Plan Before Traveling
Before traveling, research and purchase an eSIM plan from a reliable provider that offers coverage in the countries you visit. This will save you time and hassle upon arrival and potentially save you money compared to purchasing a physical SIM card.
3. Activate Your eSIM as Soon as You Arrive
To ensure seamless connectivity, activate your eSIM as soon as you arrive at your destination. This will help avoid any potential issues with network settings or compatibility.
4. Choose Wisely Between Regional Plans vs. Individual Country Plans
When choosing an eSIM plan, consider whether a regional or individual country plan would be more beneficial for your trip. Regional plans offer coverage in multiple countries, which is convenient if you visit different locations within the same region. However, individual country plans may offer better rates and coverage if you only visit one specific country.
5. Be Mindful of Data Usage
While eSIMs can make it convenient to switch between plans, they also require careful data management. Monitor your data usage and consider purchasing an additional eSIM plan if you need more data during your travels.
6. Be Prepared for Technical Difficulties
As with any technology, there may be technical difficulties when using eSIMs. Make sure to have a backup plan in case your eSIM does not work in a particular country or if there are issues with your device recognizing the eSIM.
