Holafly eSIMs: A Better Way to Stay Connected When You Travel

By Eric November 28, 2025

In today’s fast-paced world, staying connected while traveling is more crucial than ever. Gone are the days of wandering with cumbersome guidebooks or struggling to purchase a physical SIM card in a foreign language. With the rise of eSIM technology, travelers can now enjoy seamless connectivity without the hassle of swapping out tiny plastic chips. One standout company in the eSIM market is Holafly, which has made it significantly easier for globetrotters to access reliable data. Founded in 2017 and now based in Dublin, Holafly offers a user-friendly solution for travelers seeking to stay connected during their journeys. With over 200 destinations covered, their eSIMs allow users to connect to local carrier networks and enjoy unlimited data options, all while being priced by the number of days rather than gigabytes.

Setting up Holafly’s eSIM is a breeze, making it an attractive choice for both seasoned travelers and those new to international adventures. Users simply need to ensure their device is unlocked and supports eSIM technology, which is common in recent smartphones. After purchasing an eSIM, travelers can easily install it by scanning a QR code sent via email while connected to Wi-Fi. Holafly’s data-only eSIMs enable users to keep their home SIM for calls and texts, allowing apps like WhatsApp and iMessage to function normally. This flexibility is particularly beneficial for those traveling across multiple countries or for digital nomads who rely heavily on mobile data. Plans start at approximately $4 USD per day, with options for longer durations at discounted rates, making it a cost-effective solution for maintaining connectivity on the go.

What truly sets Holafly apart is its commitment to customer satisfaction. They offer 24/7 multilingual support, hotspot capabilities, and a flexible six-month refund policy, ensuring travelers have a reliable safety net. The simplicity of scanning, activating, and using the eSIM is a game-changer for anyone looking to avoid the logistical nightmares of traditional SIM cards. With Holafly, travelers can focus on enjoying their adventures rather than worrying about data plans or network compatibility. For those planning their next trip, using the code MATTK can provide a 5% discount on any eSIM purchase, making Holafly an even more appealing option for staying connected abroad.

When you’re traveling, staying connected is essential. Whether you’re figuring out the best route to your hostel, finding a place to eat, or translating a train schedule or menu, having reliable data makes life on the road infinitely easier. I still remember my early days of travel carrying a physical guidebook around as I wandered the streets looking for my accommodation.

Or, when smartphones became widespread, searching for a SIM card kiosk to buy a physical SIM, trying to poorly communicate with staff in a language I didn’t know, and spending 20 minutes swapping out tiny plastic chips.

Luckily, things have changed and life is incredibly easier thanks to eSIMs. Rather than needing a physical SIM card, you can download an app that gives you tons of high-speed data. In a world where we need to be connected for so many reasons (for example, everything in China is paid through an app, so you need data), eSIMs are great.

One company that’s become a major player in this space is
Holafly
. (Use the code MATTK to get a 5% discount.) They offer unlimited data, quick setup, and global coverage without the hassle of finding a physical SIM card.

In a world of seemingly never ending eSIM companies, they are one of the best. In this blog post, I will tell you why!

Who is Holafly?

Holafly
is a Spanish-founded company that started back in 2017 and is now based in Dublin. They offer eSIMs that you can install on your phone via QR code. Once activated, they let you connect to the internet abroad using local carrier networks. What sets Holafly apart from a lot of other providers is that over 200 of their options come with unlimited data and are priced by days rather than gigabytes. You can personalize the days from 1 up to 90 days in over 200 destinations. Holafly’s coverage is also pretty extensive. They offer service in over 200 destinations, which includes most of Europe, Asia, North America, and Latin America.

How to Set Up Holafly

The process of setting up Holafly is incredibly straightforward. Here is how to do it:

Check your phone first
– Make sure your device is unlocked and supports eSIM (
most recent iPhones and many newer Androids do
). Have a Wi-Fi connection handy for setup.

Save the email & QR
– Keep the QR code and order info somewhere safe.

Install the eSIM
– While on Wi-Fi, open the confirmation email and scan the QR code from your phone camera or tap the activation link. There are three options:

Scan the QR Code

Manual Installation

One-Button Install for iOS 17.4 or above

On iPhone: Settings -> Cellular (or Mobile Data) -> Add Cellular Plan -> scan the QR.

On Android: Settings -> Network & internet (or Connections) -> SIMs or Mobile network -> Add eSIM / Add mobile plan -> scan the QR. (Exact labels vary by phone.)

On arrival, enable data roaming for the eSIM
– Go to Cellular/Mobile Data settings, select the Holafly line and turn on Data Roaming and Mobile Data for that line. (Turn off Mobile Data for your home SIM to avoid accidental roaming charges.)

Holafly partners with local carriers, so your connection depends on whichever network is strongest in that region. Note that
Holafly
’s eSIMs are data-only. You can keep your home SIM card in your phone for texts or calls, while Holafly handles all your data. Apps like WhatsApp, iMessage, and Telegram will still work with your regular number, so you can message friends and family just like you would at home.

The “unlimited data” promise is what draws most people in, and for good reason. Most eSIM companies sell data in small bundles, which adds up quickly, especially if you’re using maps, social media, or video calls. With Holafly, you just pay for the number of days you need and get unlimited data during that time.

Plans start at around $4 USD per day, though they are cheaper if you get more days or choose their new subscription options Holafly Plans.

Plus, Holafly offers 24/7 customer support multilingual, hotspot capabilities, 15+ regional eSIMs, a global eSIM, no hidden costs, and an incredible 6 month flexible refund policy.

I think it’s one of the best eSIM options for travelers who want reliability and ease of use. It’s especially great for people visiting multiple countries or anyone who relies heavily on mobile data — bloggers, remote workers, or digital nomads. The connection has been consistent, speeds are good, and the ability to set everything up before I even leave home is a huge time-saver

At the end of the day, that’s really what makes Holafly appealing: simplicity. You don’t have to think about data, SIM cards, or network compatibility. You just scan, activate, and go. For travelers like me, that convenience is priceless.
