Holafly vs TravelSim®

International eSIM Comparison for Europe


Traditionally, travelers have always been advised to pick up a new SIM card in each country they visit.

Language barriers and technical difficulties can sometimes make this cumbersome, and upon arrival in a new destination you find yourself disconnected from the rest of the world until you hunt down your newest SIM. When traveling through Europe, where you can potentially pass through multiple countries in the space of a day, this becomes even more of a challenge.

The eSIM is solving these problems for travelers worldwide, with its easy installation and quick connectivity. Through an international eSIM, you can simply connect to a local carrier in each country you visit, without having to make any physical changes to your device. For globetrotters looking to streamline their travel experience, using eSIMs is an easy way to alleviate some of the pressure of staying connected while abroad.

But where to start when looking for an eSIM that’s right for you and your adventures? We’ve drawn up some comparisons to help you get to grips with popular eSIM features and functionalities, so you can decide just how you want to stay in touch while on the go in Europe.

TravelSim® Overview

Known for the competitive prices of our roaming plans and the extensive list of countries we cover, TravelSim® provides both eSIMs and regular SIM cards to millions of users worldwide. Through TravelSim® products you can access over 320 different mobile networks in more than 200 destinations, which can work out as much as 85% cheaper than using your own carrier for roaming.

Once you’ve activated your TravelSim® eSIM it will stay active for as long as you keep topping it up, so if you decide to follow your impulses and extend your trip, or book in to do it all again in six months time, you already have everything you need.

Holafly Overview

A relative newcomer to the scene, Holafly was founded in 2017 and since then has been providing international eSIMs serving 160 destinations around the world. Similarly to TravelSim®, Holafly eSIMs are accessed and activated through a QR code, and give the user access to their chosen data plan. They have an unlimited data roaming package for Europe, but they are a data-only service, and can’t provide a European number for calls and SMS messages.

A TravelSim® international eSIM for Europe is right for you if…

  • You love to share

    When using data through a TravelSim® international eSIM you can share this data with your friends via hotspot. You can also hotspot to other electronic devices such as laptops or tablets. It’s nice knowing that you’ll be able to help out a friend if their own roaming package leaves them in a sticky situation.

  • You’re a digital nomad

    If you plan to mix business and pleasure and work while you’re traveling, you’ll understand the importance of being able to stay connected no matter where you go. Thanks to the wide list of countries we cover, and the fact that we promise the highest speeds whichever carrier you connect to can provide, you don’t need to worry about missing a meeting or phone call. Plus an eSIM means you can manage multiple SIM profiles at once, letting you use one mobile device for both work and play.

  • You like the freedom to choose

    Extend your trip and add more charge to your eSIM – that’s fine with us. Or maybe the homesickness is too strong, and you decide to cut your travels short and pick them up again another time? Your eSIM will stay active so long as it’s charged at least once a year. You don’t have to worry about last minute decisions when you know your phone can be ready to roam at a moment’s notice.

  • You don’t have time to wait

    One of the key benefits of choosing an eSIM over a traditional SIM card is you don’t need to wait for a physical card to be delivered to you and inserted into your phone – and you don’t need to exchange it for a new one every time you cross a border. The majority of smartphones are now being made with eSIM capabilities. All that you need to do is decide on your data plan and activate it through a QR card – meaning you can be up and running in as little as five minutes.

  • You consider yourself travel savvy

    TravelSim® rates are some of the best around, and our flexible service shows just how well we understand travelers’ needs. Not only this, but we’re always striving to improve our products, and if for some reason you decide we’re not for you, we’re happy to refund you on any unused products purchased within 14 days.

Reliable data and mobile coverage is what makes the difference between feeling like a cast away and casting off.
