When you travel, staying connected is essential. Whether you’re figuring out the best route to your hostel, looking for somewhere 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 guide as I wandered the streets looking for my accommodation.
Or, when smartphones became widespread, I would search for a SIM card kiosk to buy an actual SIM card, try to communicate poorly with staff in a language I didn’t know, and spend 20 minutes swapping tiny plastic chips.
Fortunately, things have changed and life has become incredibly easier thanks to eSIMs. Instead of needing a physical SIM card, you can download an app that will give you loads 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.
One company that has become a major player in this field is Hollafly. They offer unlimited data, quick setup, and global coverage without having to find a physical SIM card.
In a world where eSIM companies seem to never go out of style, they are one of the best. In this post I will tell you why!
Who is Hollafly?
Hollafly It is a company founded in Spain and started in 2017 and is now headquartered in Dublin. They offer eSIMs that you can install on your phone via a QR code. Once activated, it allows you to connect to the Internet abroad using local carrier networks. What sets Holafly apart from a lot of other providers is that more than 200 of their plans come with unlimited data and are priced in days rather than gigabytes. You can customize days from 1 to 90 days in over 200 destinations. Holafly’s coverage is also very broad. They provide service to more than 200 destinations, which includes most of Europe, Asia, North America and Latin America.
How to set up Holafly
The Holafly setup process is incredibly straightforward. Here’s how to do it:
Check your phone first – Make sure your device is unlocked and supports eSIM (newer iPhones and many newer Android devices do). You have a Wi-Fi connection that is easy to set up.
Save email and QR – Keep the QR code and order information in a safe place.
Install the eSIM – While using 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 QR code
 - Manual installation
 - One-button installation for iOS 17.4 or above
 
Upon arrival, enable data roaming for the eSIM – Go to your cellular/mobile data settings, select your Holafly line and turn on 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 area. Note that HollaflyeSIMs eSIMs are for data only. You can keep your home SIM card in your phone for texting or calling, 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 promise of “unlimited data” is what attracts most people, and for good reason. Most eSIM companies sell data in small packages, which add up quickly, especially if you use maps, social media, or video calls. With Holafly, you only pay for the number of days you need and get unlimited data during that period.
Plans start at around $4 per day, though it’s cheaper if you get more days or choose Holafly Plans’ new subscription options.
Additionally, Holafly offers 24/7 multilingual customer support, hotspot capabilities, 15+ regional plans, a global plan, no hidden costs, and an amazing flexible 6-month 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 was stable, speeds were good, and being able to set everything up before I left the house saved a lot of time
Ultimately, that’s what makes Holafly attractive: simplicity. You don’t have to think about data, SIM cards or network compatibility. Simply scan, activate and go. For travelers like me, this convenience is priceless.
