June 4, 2024

Traveling has always been an exciting venture, filled with new experiences and adventures. But staying connected while on the go can be challenging and expensive. Enter the eSIM – a small yet powerful technological advancement that can make your travel experience seamless. Let’s dive into the world of eSIMs, and understand how to buy, install, and use one for your travels.

What Are eSIMs?

Imagine a world where you don’t have to struggle with small SIM cards every time you travel. That’s the promise of an eSIM, or embedded SIM.

An eSIM is a digital equivalent of the conventional SIM card. It can be activated without the need for physical insertion into your device. This allows you to change service providers and data packages without the necessity of removing a tangible card.

Is My Phone Compatible with eSIMs?

Before you get too excited about eSIMs, make sure your device can use them. Most modern smartphones, like the latest iPhones and high-end Android devices, are eSIM-compatible. You can find this info on your phone in settings under "About" or on the manufacturer's website by checking specs.

How to Buy an eSIM for Traveling

Step 1: Choose Your Package

Your journey with an eSIM begins with selecting the right plan. Consider your travel destination and how much data you will need. KnowRoaming offers different eSIM plans for various needs, such as single-country, regional, and global plans.

Whether you’re visiting one country or hopping across several, there’s a plan that’s right for you. Discover more about the countries and regions we cover here.

Step 2: Scan the QR Code

Once you’ve purchased your eSIM plan, you’ll receive a QR code via email. This code serves as your immediate link to connection. Make sure you have a good internet connection, ideally in your home country, before scanning this code with your phone. To learn about how to scan the QR code with one device, click here.

Step 3: Switch to eSIM When You Arrive

Once you land at your destination, it’s time to activate your eSIM. Go to your phone’s settings and switch your primary data connection to the eSIM. This process is usually straightforward and involves a few taps on your device.

Setup Not Working?

If your mobile device is carrier-locked, reach out to your service provider and ask them to unlock your phone.

Step 4: Turn on Roaming and Connect

Finally, enable roaming on your device to connect to the local network. This step is essential to ensure you can access data and stay connected throughout your trip. When roaming is on, your eSIM will connect to the best network signal, ensuring reliable service wherever you are.
