Holafly, our opinion on eSIM cards for traveling abroad

Last update : 25 February 2024

Want to travel abroad without worrying about your internet package and looking for opinions on Holafly and eSIMs? It’s getting harder and harder for us to imagine traveling abroad without using our phones… Whether it’s to communicate with our loved ones, find our way around with GPS or simply publish our travel photos and videos on social networks, having data when traveling often proves indispensable! So that we can continue to use the Internet on our phones from abroad, we had the opportunity to test Holafly’s eSIMs during a trip to Switzerland. Now that we’re back home, this article gives you our feedback and our opinion on Holafly. 

How do Holafly’s eSIMs work? 

How does an eSIM work?

eSIMs work on the same principle as SIM cards, except that they are dematerialized. Once you’ve placed your order, simply scan the QR code to activate the eSIM on your phone. It’s easy enough to do, and works without having to remove your main SIM. Thanks to this, you’ll be able to use the data from your Holafly package while keeping your main number on WhatsApp.
On the day of your departure, simply make sure to deactivate the cellular network on your main sim card in the settings so that the Holafly package can take over when you travel abroad.

What phones are compatible with eSIM?

Before opting for an eSIM, we also recommend that you carefully check whether your phone is compatible with this technology. Note, however, that by 2024, more than 200 models will be compatible with eSIM. If your phone is recent, this shouldn’t be a problem, but we’ve added a non-exhaustive list of compatible models. If you can’t find your model, don’t hesitate to ask online or directly with the brand.

What countries will Holafly cover in 2024?

Holafly covers over 160 destinations worldwide, which is really very convenient. So you should easily find the eSIM you need. Note that packages and rates differ depending on the countries you select, so we recommend you take a look at their destinations list for full conditions and rates.

Why order a Holafly eSIM card before traveling abroad? Our opinion

The first reason, in our opinion, is to avoid going overboard when traveling abroad, to benefit from unlimited datas while keeping your number to exchange via WhatsApp with our loved ones. Maybe you already have an international package and are wondering why you should take an eSIM when traveling abroad? The main reason is that not all countries are covered by this type of package. On this subject, we advise you to systematically check if the country you’re planning to visit is covered by it, as this could save you some nice surprises and blow your vacation budget.

This is what happened to us recently with our journey to Montenegro… A few seconds of data to get our bearings and find a local sim and it’s €50 out of pocket for us. 😅 Suffice to say, we wished we’d anticipated this and had an eSIM with us at the time! The last good reason to order an eSIM before you go on vacation is that you can receive a code to activate it, without having to go anywhere or wait, which is just great!

What are the advantages of traveling with a Holafly eSIM? Our opinion

The main advantage is that with a Holafly eSIM, there’s no need to look for a local SIM as soon as you arrive on vacation. Simply visit the Holafly website to order your eSIM before your trip, and you’re all set! What’s more, our data plans are unlimited, so you’ll be able to surf at high speed with no limits during your trip. It’s fast, simple and efficient – in short, we love it. As for us, we tested an eSIM during our recent trip to Switzerland, and we’ll give you our opinion at the end of the article!

What formulas are available for your trips abroad?

We recommend that you go directly to the Holafly website to see if your next destination is covered. If you’re going on a roadtrip, Holafly also offers multi-country packages such as the North/South America card or the Asia card, which is even more convenient. If you’d like to try out one of the packages offered by HolaFly, we’re sharing a 5% promo code. Simply enter the code DECOUVRIRENSEMBLE5 when placing your order.

Our Holafly review after a trip to Switzerland

We had the opportunity to test a Holafly eSIM during our last trip to Switzerland. As Switzerland wasn’t covered in our current package, we needed a local SIM. And there was no question of reliving our Montenegro experience! 😅 So we easily set up our eSIM before our departure directly from home. The eSIM option enabled us to keep our number on WhatsApp, which was important to us.

On this trip we encountered no problems with the eSIM. We were even able to get an Internet connection in the heart of the Bernese Jura – quite a feat! Our experience with our Holafly eSIM was therefore very satisfactory, and from now on we’ll be going through them for our next trips abroad that wouldn’t be covered by our respective packages. A great plan that we wanted to share with you today, in the hope that it will allow you to travel abroad serenely, while staying connected!

Holafly review #1: Impeccable customer service

Customer service impeccable and accessible at all times, in the language of our choice (French language in my case). Nothing but positive things to say about my experience with Holafly. Interesting site because it allows you to obtain cellular data while keeping your phone number. I preferred this to buying a SIM card.

Date of experience: 01 June 2023


Holafly review #2: Simple,fast and efficient. 

Simple, fast and efficient… moreover no need to change sim with the esim you keep your number and your sim, and can activate it when you want, but too bad for me my mobile was not compatible and the holafly service refunded me in full… I really recommend it for people leaving abroad. Thank you holafly
