When traveling, staying connected is essential. Whether it’s figuring out the best route to your hostel, finding somewhere to eat, or translating a train timetable or menu, having reliable data makes life on the road infinitely easier. I still remember my first days of traveling with a physical guide as I wandered the streets looking for my accommodation.
Or, when smartphones became widespread, searching for a SIM kiosk to buy a physical SIM card, trying to miscommunicate with the staff in a language I didn’t know, and spending 20 minutes exchanging tiny plastic shavings.
Fortunately, 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 many reasons (for example, everything in China is paid through an app, so you need data), eSIMs are great.
A company that has become a major player in this field is Holafly. (Use code MATTK for 5% off.) They offer unlimited data, quick setup, and global coverage without having to find a physical SIM card.
In a world where eSIM companies seem endless, these are some of the best. In this blog post, I’ll explain why!
Who is Holafly?
Holafly is a Spanish company that started operations in 2017 and is now based in Dublin. They offer eSIMs that you can install on your phone via a QR code. Once activated, they allow you to connect to the Internet abroad via local operator networks. What sets Holafly apart from many other providers is that over 200 of their options include unlimited data and are billed by days rather than gigabytes. You can customize days from 1 to 90 days in over 200 destinations. Holafly’s coverage is also quite extensive. They offer services to over 200 destinations, including most of Europe, Asia, North America and Latin America.
How to configure Holafly The Holafly setup process is incredibly simple. Here’s how to do it:
Check your phone first – Make sure your device is unlocked and supports eSIM (newer iPhones and many newer Androids do this). Have Wi-Fi handy for setup.
Save Email and QR – Keep the QR code and order information in a safe place.
Install the eSIM – While on Wi-Fi, open the confirmation email and scan the QR code from your phone’s camera or tap the activation link. There are three options:
Scan the QRCode Manual installation One-button installation for iOS 17.4 or above On iPhone: Settings -> Cellular (or Mobile Data) -> Add a cellular plan -> scan the QR.
On Android: Settings -> Network & internet (or Connections) -> SIM or Mobile network -> Add eSIM / Add mobile plan -> scan the QR. (Exact labels vary by phone.)
When you arrive, activate data roaming for the eSIM – Go to cellular/mobile data settings, select the Holafly line and enable data roaming and mobile data for that line. (Turn off mobile data for your home SIM card to avoid accidental roaming charges.)
Holafly partners with local carriers, so your connection depends on the strongest network in that region. Note that HolaflyeSIMs are data only. You can keep your home SIM card in your phone for texting or calling, while Holafly manages all your data. Apps like WhatsApp, iMessage and Telegram will still work with your usual number, so you can message friends and family just like you would at home.
The promise of “unlimited data” is what attracts most people, and for good reason. Most eSIM companies sell data in small batches, which adds up quickly, especially if you use cards, social media, or video calls. With Holafly, you simply pay for the number of days you need and get unlimited data during that period.
Plans start at around $4 per day, although they are cheaper if you get more days or choose their new Holafly Plans subscription options.
Additionally, Holafly offers 24/7 multilingual customer support, hotspot capabilities, 15+ regional eSIMs, 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 looking for reliability and ease of use. This is especially great for people visiting multiple countries or anyone who relies heavily on mobile data: bloggers, remote workers, or digital nomads. The connection is consistent, the speeds are good, and the ability to set everything up before you even leave the house is a huge time saver.
Ultimately, that’s really what makes Holafly appealing: simplicity. You don’t have to think about data, SIM cards or network compatibility. Just scan, activate and go. For travelers like me, this convenience is priceless.
