PuraSim vs Holafly — Honest Comparison 2026

In short: PuraSim and Holafly are two eSIMs designed for travel without roaming, but they operate on different models: Holafly sells "unlimited data" with speed reduction after a daily threshold, while PuraSim sells actual data packages at 4G/5G speeds without hidden cuts, with over 200 destinations in its catalog and 24/7 support in all languages via email and WhatsApp.

If you've read this far, it's because you're about to book a trip and don't want to take chances with internet access as soon as you land. This is a reasonable decision: running out of data at passport control, not knowing how to get to your hotel, or being unable to open the voucher for an excursion you booked three months ago can ruin the first few hours of any trip. Here, you won't find an inflated table of stars or "the number one option on the market." You'll find the points where PuraSim and Holafly are similar, the points where they truly differ, and also when you don't need either of them.

What exactly are they and how are they similar?

Both PuraSim and Holafly are travel eSIM providers: they sell digital data profiles that you install by scanning a QR code, without a physical card, and that connect you to a local or regional mobile network as soon as they are activated. Neither of them is the network operator: both work with roaming agreements with local operators (Movistar, Vodafone, Orange, DoCoMo, AIS, depending on the country) and resell that access packaged in data plans.

The difference is not in the technology—the eSIM standard is the same for all—but in how they package and sell that data, and what happens when something doesn't work at 6 AM in an airport you don't know. If you're still unclear about what an eSIM is or why it replaces traditional roaming, you should first read about the difference between eSIM and roaming: it will save you confusion later in this article.

The point that truly separates them: "unlimited" data vs. real data

This is the key to the entire comparison, which is why we're putting it first. Holafly built its brand around the word "unlimited." It sounds good, but in practice, most eSIM operators that offer "unlimited" plans—Holafly included—apply a speed reduction (throttling) once a daily consumption threshold is exceeded, which is common in the industry and usually detailed in the fine print of the plan. This means you can remain "connected," but browse at a much slower speed than you had in the first hours of the day. For checking Google Maps or sending messages, you won't notice it. For a work video call or uploading live video from a terrace in Lisbon, you will.

PuraSim takes a different approach: it sells data packages with a defined amount of GB, at full network speed (4G or 5G depending on the country and local operator) for the entire validity of the plan, without progressive cuts. The downside is that if you run out of GB, you have to extend the plan; there is no "unlimited" backup layer. For most traveler profiles—map consultation, messaging, social media, occasional streaming—this is not a real problem if you choose the right GB package from the start.

Put another way: if your priority is never having to think about a data counter and you don't mind losing speed after a certain point, Holafly's "unlimited" approach might suit you. If you prefer to know exactly what speed you'll have throughout your trip and only pay for what you're going to use, PuraSim's model makes more sense. There's no universal answer; it depends on whether you're going to work from your laptop in a Bali hotel or just need Google Maps and WhatsApp during a long weekend in Amsterdam.

Coverage and real speed on the ground

Coverage "on paper" is rarely the problem; the problem arises in very specific places. In the London underground, there's no signal for any eSIM or physical SIM, so download your route map before going down to the station. On high-speed trains like the AVE or TGV, the signal comes and goes when passing through long tunnels, and no eSIM prevents this because it depends on the tower you connect to in each section, not the provider. In the Medina of Fes or narrow alleys of European historic centers, the signal may drop simply due to the density of stone buildings around, not because the plan fails.

That said, both PuraSim and Holafly rely on the same local operators in most countries, so the basic network coverage is usually equivalent. The real difference you'll notice day-to-day is the sustained speed throughout the plan, which is precisely the point of the previous section. If you want to understand why the "published" speed on a provider's website almost never matches what you measure on your phone, you should read about real speed vs. published speed before comparing plans based solely on the number of GB.

PuraSim vs Holafly: comparison by criteria

As you can see, in terms of compatibility and activation mechanism, they are practically identical: the eSIM standard works the same regardless of the provider. The differences that truly matter in the decision lie in the data model and support, which are precisely the two areas where a problem is most noticeable when it arises.

Support: what happens when the eSIM doesn't connect upon landing

Support only matters at the worst possible moment: you've just landed, you've been flying for eight hours, your phone is at 12% battery, and the eSIM can't find a network. That's where the difference between one provider and another becomes apparent, not on the pretty website or in the purchasing process.

PuraSim offers 24/7 support in all languages via email and WhatsApp, which practically means you can write from the airport using the terminal's own Wi-Fi, without relying on finding someone who speaks your language. Holafly also provides support in several languages, but it's advisable to check the language and channel available depending on the time of day, as response times can vary during peak hours like weekends or holidays in the support's country of origin.

A practical tip that almost no one gives: before leaving home, save the manual configuration instructions for your eSIM offline (not just the QR), in case the destination airport's Wi-Fi fails or takes time to grant access, and you need to activate the profile without relying on a new download.

Installation and activation: the part that determines if you arrive connected or not

There aren't major differences between providers here because the process is defined by the phone's operating system (iOS or Android), not the eSIM brand. What does change is when it's convenient to install it. Install the eSIM profile with Wi-Fi before leaving home, but don't activate it until you're about to land or have already arrived at your destination: if you activate it too early, you might waste validity data unnecessarily, because in many plans the countdown begins at the moment of the first network connection, not at the time of purchase.

Another overlooked detail: if your phone is dual SIM, leave your physical line as the secondary data and call line, and configure the eSIM as the primary data line so that map and messaging apps use the new connection by default; if you don't touch that configuration, your phone might continue trying to use roaming data from your Spanish operator without you realizing it, and that's where billing surprises come in when you return. If it's your first time installing one, it's advisable to follow the step-by-step guide on how to install an eSIM before traveling.

Myths and what almost no one tells you

There are several ideas circulating about travel eSIMs that should be debunked before buying either one:

• "Unlimited" doesn't always mean what you think. In the industry, "unlimited data" usually comes with a speed reduction after a certain daily consumption. This is not exclusive to any provider: it's a common commercial model. Always read the conditions of the specific plan before buying, don't just rely on the headline.
• Buying the most expensive eSIM doesn't give you better coverage. Coverage is determined by the agreement with the local operator, not the price of the plan. A cheap plan with the right operator can give you better signal than an expensive one with a secondary operator in that country.
• You don't need to buy the plan with the most GB "just in case." Most travelers with normal usage (maps, messaging, social media) spend much less than they think. It's better to calculate your actual consumption from recent trips and top up on the fly if necessary, rather than overpaying for a buffer you won't use.
• Activating the eSIM does not erase your physical SIM. This is a common fear, especially among users installing an eSIM for the first time. The profiles coexist without issue, and you can delete the travel profile when you return home.
• A regional plan is not always cheaper than several country-specific plans. If you're spending three days in France and one in Belgium passing through, a country-specific plan might be more beneficial than a regional one designed for long stays in several countries. It's advisable to look at it case by case, and if you're traveling to several destinations on the same trip, understanding the difference between regional eSIM and country eSIM will help.

When it's NOT advisable to buy either of them

This is what almost no comparison tool will tell you, but it's honest to say: if you're going to spend a weekend in a city in your own Eurozone with a Spanish plan that already includes roaming in the EU at no additional cost, you don't need to buy anything. Your usual plan already covers you, and buying an eSIM would be an unnecessary expense. The same applies if you're going to be in your hotel all the time with decent Wi-Fi and only go out for meals: consider whether a pocket Wi-Fi shared with your group might be more beneficial than an individual eSIM for each person; there are real differences between both options worth knowing, especially for group or family trips, and we explain them in eSIM vs. portable Wi-Fi.

It also makes no sense to buy a data eSIM if your real priority is to have a local phone number for calls (e.g., for arrangements with a vacation rental or a hospital at your destination): travel eSIMs are for data, they don't replace a line with a local number for incoming calls in most cases. And if you're traveling to a destination where you already have a local SIM from a previous trip with valid balance, it might be more convenient to top it up than to buy a new profile, even if that means finding a physical top-up point.

Europe, United States, and Spain: specific use cases

For a trip through several countries in the European Union, a single regional plan is usually the most convenient because you don't have to change eSIMs when crossing borders; you can review the eSIM for Europe plan if your route includes more than one country. For the United States, keep in mind that coverage varies significantly between urban and rural areas depending on the operator each provider works with: on the road in sparsely populated areas of the Midwest or Southwest, the signal may be more limited than in cities like New York or Los Angeles, so download route maps before leaving; you can view the eSIM for the United States plan. And if you are a resident and need an additional data line within Spain—for a second device, a work tablet, or as a backup—there is also an eSIM for Spain.

If your question isn't so much "PuraSim or Holafly" but whether an eSIM is better for you compared to other alternatives available at your destination, such as the tourist SIM card sold at the airport itself, it's worth reading the comparison between tourist card and eSIM before deciding.

Frequently Asked Questions

Is PuraSim or Holafly better?

It depends on what you prioritize. If you prefer to know exactly the speed you'll have throughout your trip and pay for the data you'll actually consume, PuraSim's model of full-speed GB packages fits better. If you don't mind losing speed after a daily threshold in exchange for not thinking about a data counter, Holafly's "unlimited" model might be your option. There is no single winner valid for all traveler profiles.

Is Holafly's "unlimited" data truly unlimited?

Internet access is not cut off, but speed is reduced after a certain daily consumption specified in the contracted plan, which is common in this type of tariff in the sector. It's advisable to review the specific conditions of the plan you're going to buy before deciding based solely on the word "unlimited."

Can I switch from PuraSim to Holafly (or vice versa) mid-trip?

Yes, technically you can install multiple eSIM profiles on the same phone as long as the device supports it, and activate the one you're interested in at any given moment. What you cannot do is use two active data profiles simultaneously on most mobile phones: you have to change which one is active for data.

What happens if I run out of eSIM data in the middle of my trip?

With PuraSim, you can top up your data package from the customer area without having to reinstall anything. With "unlimited" plans like Holafly, what usually happens is that the already activated speed reduction is maintained; you usually don't lose connection, but you do have less speed than you had at the beginning.

Do I need Wi-Fi to activate the eSIM when I arrive at my destination?

You need an internet connection (Wi-Fi or data) to download the eSIM profile the first time, which is why it's recommended to install it with Wi-Fi before leaving home. Once installed, the activation of the local network upon landing is automatic and does not require additional Wi-Fi.

Do PuraSim and Holafly eSIMs work on the same types of phones?

Yes, both rely on the same device eSIM standard, not on each provider. If your phone is eSIM compatible—most mid-to-high-end from 2018-2019, such as iPhone XS and later or Samsung Galaxy S20 and later—it will work with either.

Is there a real price difference between PuraSim and Holafly?

Prices change depending on the destination, duration, and amount of data, and they vary frequently on both platforms, so the most reliable thing is to check the current price directly on each website for your specific destination at the time of purchase, instead of relying on a figure you may have seen in another article.
