In short: The real money-saving alternative to Holafly is not another unlimited data brand, but a pay-per-gigabyte plan valid for up to 30 days. You pay for what you use, not for a daily counter, and you still land with internet access from the first minute. Unlimited data is only worthwhile if you plan to do a lot of streaming on a short trip.
Holafly popularized the unlimited data eSIM for travel and remains one of the best-known brands in the sector. But "known" is not the same as "cheapest," and it almost never is. If you're looking for an alternative to Holafly that costs less and still works as soon as you land—without visiting a local operator's store, without accidentally activating roaming, without bill shock—this guide compares the unlimited data model with pay-per-gigabyte plans and explains, critically, when each is more suitable.
Why look for a Holafly alternative
The most sought-after alternative to Holafly is one that offers the same service—immediate connection at destination, no roaming, no need to find a store upon arrival—at a lower price. Holafly charges daily for unlimited data, a model that's easy to understand but expensive for long trips or if your actual usage is moderate. A pay-per-gigabyte plan valid for several weeks is usually much more economical for the typical traveler's usage.
Those who start looking for alternatives usually agree on something similar: they found the daily rate expensive when calculating the entire trip, noticed that the speed decreased after a certain daily consumption despite being called "unlimited," or simply checked their phone upon return and saw that they hadn't used anywhere near what they paid for. No "unlimited" promise replaces checking how many gigabytes you actually use on a normal travel day, and that calculation is what changes the decision.
Before automatically renewing with the same old brand, it's worth comparing. You can also see how the unlimited model performs against another popular option in the comparison between Saily and Holafly, which illustrates the differences between charging daily and charging by consumption.
Practical tip: a tourist with normal mobile use—maps, messaging, social media without continuous video playback—rarely exceeds 1-1.5 GB per day. With that, a 5 to 10 GB plan easily covers an entire week.
Unlimited vs. pay-per-gigabyte: what suits you
It depends mainly on two things: how much you'll use your phone without Wi-Fi and how many days your trip lasts. If you're going to stream series or games, or share your connection with another device for many hours a day, unlimited gives you peace of mind because you don't have to monitor your usage. If you use your phone normally—maps to get around, WhatsApp, occasional browsing, social media without constantly watching videos—a pay-per-gigabyte plan costs less, and you'll almost always have data left over at the end of your trip.
Holafly's model charges per calendar day, so a two-week trip multiplies the cost by fourteen daily rates, whether you've used them or not. A pay-per-gigabyte eSIM valid for up to 30 days lets you manage your consumption at your own pace, without the pressure of "I have to use it today because I've already paid for it." It also helps you avoid "unlimited with fine print": many unlimited plans reduce browsing speed after exceeding a daily consumption cap, so truly unlimited isn't always as unlimited as it sounds in advertisements.
- Short, intensive trip: unlimited can be worthwhile if you'll be doing a lot of streaming or long video calls.
- Trip of one to four weeks: a pay-per-gigabyte plan is almost always cheaper than accumulating daily rates.
- Moderate use (most travelers): 5-10 GB is more than enough, and you only pay for what you actually use.
If you're also traveling through several countries on the same trip, it's good to first understand the difference between relying on a local operator and having your own connection: the guide on what data roaming is clarifies why traditional roaming almost never beats a travel eSIM.
Alternative comparison
These are the most common alternatives to Holafly. We do not include exact price figures because they vary by destination, season, and plan duration—always check the current price on each website before purchasing—but the table helps you see each model and where the savings usually lie.
| Option | Billing Model | Typical Validity | Ideal for |
|---|---|---|---|
| Holafly | Unlimited per day | Trip duration | Short trip with heavy streaming or video calls |
| PuraSIM | Per gigabyte, various plan sizes | Up to 30 days | Normal use, trips of days or weeks |
| Saily | Per gigabyte | Variable by plan | Light occasional use |
| Airalo | Per gigabyte | Variable by plan | Comparing a wide catalog of countries |
| Spanish operator roaming | Per day or per package, outside the EU | Trip duration | Almost never: usually the most expensive option |
If you want to delve deeper into how other brands in the sector compare, you also have Airalo vs. Holafly, and if you are specifically looking to replace Airalo, the Airalo alternative follows the same logic of comparing by actual consumption instead of by brand name.
How many GB do you really need?
Before paying for unlimited data, calculate your actual consumption. Most travelers overestimate how much they spend because at home they almost always browse on Wi-Fi and have no idea how much they consume via mobile data on a normal day. Something similar happens when traveling: if you sleep in a hotel or apartment with Wi-Fi and use it at night to check your phone, mobile data consumption drops significantly compared to what one imagines before leaving. On that basis, a pay-per-gigabyte plan almost always wins in terms of value for money compared to unlimited.
Quick reference for choosing plan size
Maps, messaging, and normal browsing use little data. What really boosts consumption is social media with endless videos, streaming series or music without prior download, and long video calls. If you rely on accommodation Wi-Fi for heavy use, a 5 to 10 GB plan covers almost any week-long getaway. For month-long trips or for those who work remotely while traveling, consider 15-20 GB or combining mid-trip top-ups instead of buying too much in advance.
- Check your current monthly usage in your phone's data settings at home.
- Subtract what you'll do via Wi-Fi at your accommodation (for most, it's more than they think).
- Choose the gigabyte plan closest to that figure, without overdoing it "just in case."
A common mistake is to buy the largest plan "just in case" and return with half the gigabytes unused. If at the end of the trip you realize you've run short, you can always top up on the go; buying too much at the beginning doesn't get you anything back if there's data left over.
How to choose correctly
Beyond price, a good alternative to Holafly must meet the basics: real coverage at your destination, simple activation, and support that responds in English if something goes wrong at three in the morning in an unfamiliar airport. A cheap eSIM that doesn't connect upon landing is no saving; it's an added problem to your trip.
Look at three specific things before buying: that the eSIM uses high-quality local networks in the destination country, that activation is a one-minute process by scanning a QR code from your phone settings, and that English support is available outside office hours, because connection problems almost never give advance notice. PuraSIM covers 218 destinations and activates the eSIM in one minute, which is particularly noticeable when you land in the middle of the night and all you want is to order a taxi with Google Maps working.
If you've never installed an eSIM and are daunted by the process, the guide on how to install an eSIM walks you through the phone settings, whether Android or iPhone, and it's advisable to do it with Wi-Fi before leaving home, not at the destination airport with the rush of the next boarding.
What almost no one tells you
Here are some nuances that often don't appear in quick brand comparisons but that change the real travel experience:
- "Unlimited" doesn't always mean maximum speed. Check the plan conditions: if there's a cap on full-speed data per day and then the speed is reduced, in practice you're paying for a pay-per-gigabyte plan disguised as unlimited, and probably more expensive than an explicit one.
- The eSIM doesn't replace your local line; it coexists with it. Many people hesitate to try it for fear of "losing WhatsApp" or their number. This doesn't happen: you simply deactivate roaming data on your main line and use the new eSIM only for browsing.
- Install the eSIM in advance, but don't activate it until you arrive. You can scan the QR code and get it ready days before your flight, using your home Wi-Fi. That way, if something goes wrong with the installation, you have time to resolve it without the airport rush.
- The network name at the destination isn't always intuitive. Upon arrival, your phone might show the name of a local operator you don't recognize: this is normal; it's the network your data eSIM operates on, not an error.
- A "regional" plan isn't always cheaper than several single-country plans. If your trip is to a single destination, comparing that specific country's plan to a regional one often yields surprises: sometimes the specific one is better.
These are real first-time frictions when someone switches from an unlimited plan to a pay-per-gigabyte model, and it's good to anticipate them before they catch you mid-trip.
Switching from Holafly step-by-step
Migrating is simpler than it seems: you don't lose your Spanish number or touch your usual physical SIM. The data eSIM is a separate line that you install alongside yours, both coexisting on the same phone. You buy the plan, receive a QR code, scan it, and you're done.
The complete process, in order:
- Check that your mobile is eSIM compatible (almost all recent models are, both iPhone and mid-to-high-end Androids).
- Purchase the plan for your desired destination and receive the QR code by email.
- Scan the QR code from your mobile settings, always with Wi-Fi available, before you leave for your trip if possible.
- Upon arrival at your destination, activate mobile data on the new eSIM and make sure to leave your Spanish line with roaming deactivated.
If your question is more fundamental—what exactly an eSIM is, how it differs from traditional roaming, or why it has become the default option for so many travelers—the eSIM vs. roaming comparison resolves that basis before going into details about specific brands.
When it DOES make sense to stick with Holafly
Being honest about this is also part of choosing well. If your trip lasts three or four days, you're going to do a lot of streaming, and you don't feel like making any consumption calculations, Holafly's daily unlimited plan removes that worry and the extra cost might be worth it for the convenience. And if you're going for a short weekend to a country where your own Spanish operator already covers you at no extra cost within the European Union, you don't need to buy anything directly: check your usual rate first, because in that case, any additional eSIM would be an extra expense, not a saving.
Frequently asked questions
What is the best alternative to Holafly?
There isn't a single "best": it depends on your actual consumption. If you use little or moderate data, a pay-per-gigabyte plan like PuraSIM is usually cheaper than an unlimited daily plan. If you're going to do a lot of streaming on a short trip, unlimited might compensate for the convenience. Calculate your GB before deciding; don't rely solely on the brand name.
Is it cheaper to pay per gigabyte than for unlimited data?
For the average traveler, almost always yes. Unlimited data is charged per calendar day, so for trips of a week or more, the cost quickly escalates. A 5-10 GB plan valid for up to 30 days covers normal use—maps, messaging, social media—for significantly less money, especially if you take advantage of your accommodation's Wi-Fi at night.
Is "unlimited data" truly unlimited?
Not always. Many "unlimited" plans reduce browsing speed after exceeding a daily consumption cap, so from that point on, you browse slower even if you haven't technically "run out" of data. It's important to read the fine print of the plan: a pay-per-gigabyte plan at full speed usually performs better in practice than an already throttled unlimited plan.
Do I lose my phone number when I switch from Holafly?
No. The data eSIM is an independent line that coexists with your regular SIM or eSIM on the same mobile. You keep your Spanish number for calls and SMS without any changes, and you use the travel eSIM only for data browsing. Simply deactivate data roaming on your main line upon arrival at your destination.
Do I need a different eSIM for each country I visit?
Not always. There are country-specific plans and also regional plans that cover several destinations with a single eSIM, which are useful if you're traveling, for example, through several European countries on the same trip. For a single destination, the specific country plan is usually more suitable; for a multi-country trip, it's worth considering the regional one. You can view eSIM options for Europe if your route includes several countries on the continent.
Does the eSIM work as soon as I land, without doing anything else?
If you installed it in advance at home (with Wi-Fi) and only activate mobile data upon arrival, yes: there's no need to go to a store or wait in line at the airport. This is precisely the difference compared to buying a physical SIM at your destination, which requires finding a point of sale, sometimes with a queue, as soon as you get off the plane.
What if I run out of data halfway through my trip?
You can purchase a top-up or an additional plan directly from your mobile at any time, without needing a new QR code or reinstalling anything. This is one of the advantages of choosing a tailored pay-per-gigabyte plan: if you estimated short, you can extend it; if you have data left over, you haven't paid for something you weren't going to use.
Conclusion
Holafly works and remains a valid option for those who don't want to think about data usage for a few days. But it's rarely the cheapest option: its unlimited daily model makes long trips more expensive, and almost no one consumes as much as they end up paying for. Before renewing out of habit, calculate your actual daily gigabyte usage on a normal trip and compare it with a pay-per-gigabyte plan valid for up to 30 days. If you're looking to connect upon landing without overpaying, check out PuraSIM's eSIM and its 218 destinations, including the eSIM for Spain if you're hosting visitors from abroad, and choose the plan that truly fits your trip, not just the most popular one.
