How to choose the best unlimited eSIM for your holiday
Selecting the right unlimited eSIM for your European holiday can make a big difference in your travel experience. Here are some pointers to help you pick the best unlimited data eSIM for your trip:
- Speed and network reliability. Fast and reliable internet is a must when traveling, whether you're using maps, streaming videos, or sharing your adventures online. I suggest looking for a reliable eSIM provider that partners with the best local networks to guarantee strong coverage and fast speeds.
- Pricing and hidden fees. No one likes surprise charges, so it’s essential to check the pricing carefully to ensure there are no hidden charges and that the cost matches your budget. I recommend comparing prices to find the most affordable eSIM for your holiday in Europe.
- Device compatibility. Not all devices work with eSIMs, so double-check that your phone, tablet, or smartwatch is eSIM-compatible before buying an eSIM plan. Most devices released after 2018 support eSIMs, but it's worth confirming to avoid unwanted surprises.
- Coverage in European countries. If you plan to visit several European countries, ensure the eSIM you choose has coverage in all your destinations. Some providers offer coverage in over 30 countries, while others might be limited to just a few. Choose an eSIM provider with extensive coverage to ensure you can stay connected wherever your travels take you.

What is an unlimited eSIM?
An unlimited eSIM is a virtual SIM card that offers unlimited mobile data, so you never have to worry about data caps. It offers more freedom and flexibility than fixed eSIM plans or physical SIM cards.
But let’s not get ahead of ourselves. First, what is an eSIM? It’s simply a digital SIM card that does everything you’d expect from a SIM card, i.e., make calls, send SMS messages, and get mobile connectivity. But, unlike a traditional SIM card, which you need to insert into your device, you install an eSIM like an app.
There are two types of eSIM plans: fixed and unlimited. Fixed eSIM plans offer a predetermined amount of data and are valid for a specific number of days. Unlimited data eSIMs, on the other hand, offer unlimited data but may also have a specific validity period.
eSIM technology has evolved rapidly over the past decade, and some pundits believe phone manufacturers will ultimately ditch physical SIM cards in favor of eSIMs.
Benefits of using an unlimited eSIM for Europe
Forget about roaming charges and the hassle of switching SIM cards. With an eSIM, you can enjoy uninterrupted connectivity, whether you're exploring city streets or remote villages. Here are some of the key benefits of using an eSIM in Europe:
- No roaming charges. An unlimited eSIM eliminates the surprise roaming fees associated with traditional SIM cards, allowing you to save more money and invest more in a memorable experience in Europe.
- Access to multiple networks. eSIM providers often work with various network providers in each country. This ensures you can easily switch between providers for better coverage and stay connected wherever your travels take you.
- Instant activation: You can purchase an eSIM plan from the comfort of your home and activate it with a few clicks. And, once you arrive at your destination, you’ll be connected to the internet instantly — no need to visit a phone shop to get an eSIM or top-up.
- Unlimited data for streaming, maps, and calls via apps. An unlimited eSIM gives you unlimited data in Europe. So, whether you're streaming your favorite shows, navigating with maps, or calling home through apps like WhatsApp, you never have to worry about running out of data.
Steps to set up an unlimited eSIM for Europe
Setting up an unlimited eSIM for Europe is simple! Here's a step-by-step guide on how to set up eSIM:
- Check device compatibility. Before you purchase an eSIM plan, make sure your phone supports eSIMs. Most devices released after 2018 are compatible with eSIMs. You can check your phone's settings or look up the model online to confirm if it works with eSIMs.
- Purchase an eSIM plan. Once you’ve confirmed that your device is eSIM-compatible, select an eSIM provider offering unlimited data plans for Europe and purchase a plan. You’ll receive all the information to set up and activate your eSIM.
- Activate via QR code or app. You can set up most eSIMs by scanning a QR code or clicking the “activate” button on an app. Select an activation method and follow the provider’s instructions to install and activate the app. Tip: I recommend adding “easy eSIM setup” to your criteria for selecting a provider for Europe. All the eSIMs on this list are easy to set up and use.
