In short: PuraSim and Yesim are travel eSIMs that prevent roaming, but they differ in price per GB, ease of activation, and support. PuraSim offers a fixed price, app-free activation, and 24/7 Spanish support; Yesim relies on its own app with global plans. For a Spanish traveler, PuraSim is usually simpler and more economical.
If you're deciding between PuraSim and Yesim for your next trip, this comparison saves you the trouble of opening fifteen tabs. Both are travel eSIMs that provide data abroad without roaming, but they are not the same in coverage, prices, or something that many Spanish people care about: support in their language when something goes wrong. Here we compare them head-to-head with clear criteria—price, ease, support—so you can choose based on data and not on hunches.
PuraSim vs Yesim: quick summary
In short: both give you travel data without roaming, with QR installation. Yesim is a platform with an app and global plans; PuraSim focuses on simplicity, adjusted prices by destination, and 24/7 Spanish support. If you value being served in your language and a frictionless purchase, PuraSim fits better; if you are looking for an app with extras, check out Yesim.
The decision is rarely "one is good and the other is bad." Both fulfill the basic function—connecting you abroad without bill surprises—so what makes the difference are the details: how much you pay for the GB you will actually use, what happens if the QR doesn't scan at eleven at night, and how intuitive everything is. Before getting into the matter, if you still have doubts about what this type of profile exactly is, review what a virtual eSIM is.

What each one is
Both PuraSim and Yesim sell eSIM profiles that you install on your mobile to have data in another country, without changing your card or losing your number. The difference lies in the approach: where they place the emphasis and which traveler they target.
Yesim positions itself as a platform with its own app, country and global plans, and some extra features within its application. It is a well-known option in the world of international eSIMs, aimed at those who want to manage everything from an app. PuraSim takes the path of deliberate simplicity: a wide catalog of destinations, activation in 1 minute, fixed price by destination, and customer service in Spanish that responds at any time. The philosophy is that buying and using an eSIM should not require a manual. If your trip includes several countries, it is convenient to first understand the difference between a regional plan and a country plan before comparing prices.
Prices and data plans
Regarding prices, the key is not the number you see in the advertisement, but how much you end up paying for the GBs you use in your specific destination. PuraSim works with adjusted plans by country and fixed prices, with no hidden surcharges. Yesim offers country and global plans; global plans provide flexibility but are usually more expensive per GB than a single-country plan.
Comparison of price criteria (indicative; check the real price of each plan before buying):
| Criterion | PuraSim | Yesim |
|---|---|---|
| Country plans | Yes, extensive | Yes |
| Global plans | Yes (regional and worldwide) | Yes |
| Price per GB in single destination | Very competitive | Competitive, increases in global plans |
| Hidden fees | No, fixed price | Depends on the plan |
| Starting price | Adjusted by destination, check current price | Variable |
Tip for good comparison: don't just look at the price of the cheapest plan. Divide the price by the GBs you will actually use during your travel days. A "cheap" plan with few GBs can end up being more expensive than one with a fixed price and plenty of data.
To pinpoint how many GB you need and avoid overpaying, if your destination is Europe, take a look at the eSIM plan for Europe and calculate consumption based on your type of trip.

Coverage and destinations
Here both play in the same league: extensive catalogs that cover the usual destinations for Spanish travelers. PuraSim offers coverage in more than 200 destinations by connecting to premium local networks, and Yesim also has an extensive global network. The practical difference is more in the plan you choose than in the brand.
What really matters about coverage is not the total number of countries, but that it works well in your specific destination. Both rely on local operator networks, so the signal in the city is usually good with both. Where you might notice differences is in:
- Regional plans: if you are touring Europe or Asia, check which exact countries are included in each regional plan. Not all include the same ones.
- Unlimited data: some plans offer "unlimited" with reduced speed after exceeding a certain threshold. Read the fine print for both.
- eSIM vs roaming: compared to your usual operator, either of them wins in terms of spending control outside the EU. We detail it in eSIM vs roaming.
For specific destinations, always compare the plan details of each provider with the country you are traveling to.
Common myths and mistakes when choosing a travel eSIM
Before deciding between PuraSim and Yesim—or between any other option on the market—it's worth debunking a few myths circulating about eSIMs that could make you lose money, or run out of data on the very first day of your trip.
Myth 1: "My phone is eSIM compatible, so I can install any profile." Not always. Many phones bought with a contract in the United States come with the eSIM locked to that operator, even if the model theoretically supports it. Before paying anything, go to Settings → Mobile Data (or the Android equivalent) and check if the option to add an eSIM plan appears. If it doesn't appear, or your phone forces you to go through your original operator, that device is locked, and no travel eSIM—neither PuraSim nor Yesim—will work until you unlock it.
Myth 2: "I can install the eSIM when I land, at the airport." This is the most common mistake and the one that causes the most frustration. To download the eSIM profile, you need Wi-Fi, and many airports have slow public networks or require prior registration via SMS. Install and activate the eSIM with your home Wi-Fi before heading to the airport. That way, when you land, you just need to activate the data in settings, without depending on finding decent Wi-Fi coverage with your luggage in tow.
Myth 3: "The more GB, the better." Buying too much is a waste of money if your trip is three days long and you're only going to use maps and messaging. Calculate your actual consumption: a city weekend with Google Maps, WhatsApp, and Instagram in normal mode rarely exceeds two or three GB. This calculation, more than the brand you choose, is what saves you the most money.
Myth 4: "All eSIMs give the same speed because the plan says 5G." The actual speed depends on the local operator the profile connects to in each country, not just the plan's label. Two eSIMs with "5G" on the spec sheet can provide very different experiences depending on which local network they latch onto. If you want to understand why the advertised data and your phone's data almost never match, you can find out why in real speed vs. advertised speed.
A fact almost no one mentions: some countries—India, Turkey, or the United Arab Emirates are common examples—sometimes require additional registration with an identity document to activate certain mobile data services. Before traveling to a destination with stricter telecommunications regulations, check the specific requirements so you don't encounter surprises on the first day.
And here's the advice that really saves you money: when NOT to buy PuraSim or Yesim. If you're traveling within the European Union with a Spanish plan that includes data roaming at no extra cost, your operator already covers you in the rest of the EU. Buying an additional eSIM in that case is an unnecessary expense: for a long weekend in Lisbon or Rome, your Spanish plan already covers you. The PuraSim vs Yesim comparison makes sense when you leave that free roaming zone, which is where the price and support difference really show.
Ease of use and Spanish support
This is where PuraSim makes its mark. Installation for both is via QR and takes a minute, but when something goes wrong—the QR doesn't scan, the eSIM doesn't connect on landing—what saves the trip is support that understands you. PuraSim offers 24/7 Spanish-language support, and that, late at night in another country, is appreciated.
Yesim manages much of the experience from its app, which is convenient if you like to have everything in one place, but it adds a step: downloading and learning the application. PuraSim reduces friction to a minimum: you buy on the website, receive the QR by email, and install it directly in your phone settings, without intermediary apps. For travelers who don't want complications—or for those who help less tech-savvy family members set up their phones—that simplicity is valuable. If it's your first eSIM, the guide on how to install an eSIM makes it clear in five minutes.
Which to choose based on your profile?
There's no universal winner, there's a winner for you. If you're a Spanish traveler who wants a fixed price, zero friction, and support in your language if a problem arises, PuraSim is the natural choice. If you prefer to manage everything from an app with extra features and don't mind the support language, Yesim might suit you.
Quick guide by profile:
- Occasional Spanish traveler: PuraSim, for Spanish support and simplicity.
- App and extras lover: Yesim, if you value managing everything from the application.
- Multi-country trip: compare the regional plans of both and stick with the one that covers exactly your countries at the best price per GB.
- Someone helping less tech-savvy family: PuraSim, because installing via QR without an app is easier to explain.
If your plan is to carry the eSIM in your suitcase like you would a charger, and you're still undecided between that and other travel connectivity solutions, also compare it with the physical tourist card, which in some destinations is still the alternative offered upon landing.
Frequently asked questions
Is PuraSim or Yesim better?
It depends on what you value. For a Spanish traveler looking for a fixed price, hassle-free activation, and 24/7 Spanish support, PuraSim is usually the better option. If you prefer to manage everything from an app with extra features, Yesim is an alternative to consider. Both fulfill the basic function of providing you with data without roaming.
Which has a better price, PuraSim or Yesim?
For a single destination, PuraSim's country plans usually offer a very competitive and fixed price per GB, without surcharges. Yesim is competitive but its global plans tend to be more expensive per GB. The key is to divide the price by the GB you will actually use on your trip.
Do I need to download an app to use PuraSim?
No. With PuraSim, you buy on the website, receive the QR by email, and install it directly in your phone settings, without intermediary apps. Yesim, on the other hand, relies heavily on its application for much of the experience, which adds a download and learning step.
Do both work without changing my SIM card?
Yes. Both PuraSim and Yesim install an eSIM profile that coexists with your main SIM or eSIM. You keep your Spanish number for calls and SMS and use the travel eSIM only for data, all at once thanks to Dual SIM.
Can I try PuraSim if I've used Yesim before?
Of course. You can have several eSIMs installed on the same phone and activate the one you want for each trip. Nothing ties you to a single provider: many travelers compare by destination and choose the cheapest or most convenient plan each time.
Do I need Wi-Fi to activate the eSIM before traveling?
Yes, to download the eSIM profile you need a Wi-Fi connection, so do it calmly from home before heading to the airport. Relying on finding decent Wi-Fi upon landing is the most common way to start a trip without data for the first few hours, with both PuraSim and Yesim.
What happens if my destination requires special registration to activate the eSIM?
Some countries with stricter telecommunications regulations—India, Turkey, or the United Arab Emirates, among others—may require additional registration with an identity document for certain data services. Check the specific requirements for your destination before traveling; this is not exclusive to PuraSim or Yesim, it is a condition imposed by the country.
Conclusion
PuraSim and Yesim solve the same problem in different ways: Yesim with an app and global plans, PuraSim with a fixed price, 1-minute activation, and Spanish support at any time. For the Spanish traveler who wants simplicity and to be understood if something goes wrong, the balance tips towards PuraSim. Compare the plans for your destination and choose the eSIM that best suits your trip.
