Holafly is a new startup eSIM data plan company based out of Dublin. I thought their service looked interesting, especially since many of their data plans are unlimited, include some calling minutes, and the prices are affordable.
But I’ve found that there can often be technical quirks when using any international eSIM data plan so I wanted to do a hands-on Holafly eSIM Review to see how they stacked up against other eSIM data plans I’ve used in Europe.

How I Tested My Holafly eSIM & Why Trust Me

For this Holafly test, I used Holafly’s 15-day unlimited data eSIM plan on my iPhone 14 Pro for a two-week trip to Italy. This trip was split between Rome and Naples but I took frequent day trips outside the cities (Capri, Pompeii, on the train between Rome and Naples, etc.).
During past trips to Europe, I’ve tested the Orange Holiday Europe data plan and the Bouygues Telecom Vacation Prepaid Data Plan. I’ve also tried using T-Mobile’s international data plan (the mobile carrier I use at home).
I’ve also written extensively about using data plans in Europe so check out The Savvy Backpacker’s Guide To Using Data Plans in Europe and How To Buy A SIM Card and Data Plan in Europe.
Holafly Plan Options, Prices, and Country Coverage

Ok, let’s dive into how Holafly works and things you might want to know before buying their service.
Holafly’s Unlimited Data Plan Prices

Holafly’s Europe and North America eSIM plans all come with unlimited data with customizable days—from 1 up to 90 days (so you only pay for what you need).
Holafly’s per-day price gets cheaper as the plan length increases, so a 7-day plan is about $4.27/day and the 21-day plan is about $3/day. You’ll want to poke around the Holafly website to see the exact specifics of your destination’s data package options.
NOTE: I’m always a little skeptical about “unlimited” data plans because local providers might throttle data if the user starts consuming excess data—for example, your data might get slowed down if you stream lots of Netflix, etc. I’ve never experienced any data throttling but it’s something to keep in mind.
Country/Region Options
Holafly offers eSIM data plans for over 200 destinations—visit the Holafly website to see the full list of countries they cover.
As mentioned before, I tested their Italy eSIM but Holafly also offers a “Europe” eSIM that covers more than 40 European countries—including Turkey, United Kingdom, Spain, Italy, Switzerland, France, Germany, Greece, Andorra, Portugal, Netherlands, Ireland, Serbia, Norway, Poland, Iceland, Austria, Croatia, Sweden, Bulgaria, Belgium, Macedonia, Malta, Denmark, Cyprus, Hungary, Romania, Czech Republic, Finland, Monaco, Lithuania, Ukraine, Latvia, Estonia, Slovakia, Slovenia, Isle of Man, Luxembourg, Gibraltar, Liechtenstein.
What Mobile Networks Does Holafly Use?
Holafly isn’t a mobile provider—i.e. they don’t own the mobile towers. Holafly simply partners with local providers and essentially rents bandwidth from those large companies. So, in Italy for example, you’re actually connected to the Wind Tre network (in France you connect to SFR, the US is AT&T, Germany is T-Mobile, etc.).
In most cases, you’ll get the same service and speeds as everyone else on the network but during heavy network usage, some users report slightly slower speeds (again, this varies by network).
[DISCONTINUED] European Phone Number With 60 Minutes of Calling Credit
UPDATE: In June 2023 Holafly updated their European eSIM data plans to include a European phone number which includes 60 minutes worth of calling to other European phones. However, it appears as if this service has been discontinued as of the summer of 2024.
Setting Up, Installing, and Activating Your Holafly Service

UPDATE (March 2024): Apple’s iOS 17.4 update included a great new automatic eSIM installation and activation feature—making setting up and managing your eSIM much easier. Simply follow the prompts on your phone and it will walk you through the process.
It’s important to not activate your Holafly eSIM until you’re at your destination.
That said, this process is a little confusing since you can install the eSIM while you’re home but then it’s kind of easy to accidentally activate the service while you’re setting everything up.
If in doubt, wait to install your Holifly eSIM until the morning of your flight—this way you won’t eat too much into your plan’s validity period if you do accidentally activate your plan too early.
So in this section, I’ll try to walk you through the process of installing the eSIM and then activating the service.
Installing and Activating Your Holafly eSIM

Once you purchase your Holafly data package, you’ll get an email with a QR code (you can also type in a code if you can’t scan the QR code). You simply scan the QR code with your phone and it walks you through the activation process.

Your phone will prompt you to make a few setting changes and then your service is activated. It will automatically connect to the local provider.
It was surprisingly simple.
Holafly eSIM Real World Performance

I was skeptical of Holafly before using their service (especially since they offer “unlimited data”) but I was extremely happy with Holafly’s performance. I mostly got 5G speeds but sometimes got LTE/4G speeds—I never noticed any data throttling.
My Google Maps/Google searches worked flawlessly, my iMessage never had any issues sending photos and videos, all my social media posts went through quickly, and my mobile data never had any issues. I will note that I never used Holafly to stream large amounts of data, so I can’t comment on how that might affect performance.
In short, my Holafly data worked very well for the entire two weeks of my trip to Italy.
Naturally, I can’t comment on how Holafly works in other parts of the world but I’m confident that it will work similarly throughout Europe and other developed nations.
Is Holafly A Good Deal and My Final Thoughts

I think Holafly is a great deal for travelers who want an affordable, no-hassle international data plan that provides great speed and a very fair price. I was seriously expecting to have slow speeds (or at least some kind of issues) but everything worked super well.
And Holafly is even more impressive now that their European plans come with a European phone number.
My 15-day service was $50.9—which comes out to basically $3.39 a day (they have plan options that range from 1 day to 90 days). Most people’s domestic carriers will charge $10+/day for international service and data speeds are often still slow so $3/day is a great deal.
