eSIM for Traveling to Europe from Mexico — Practical Guide 2026

Which eSIM to use when traveling from Mexico to Europe?

Before answering which eSIM to use, let's clarify what an eSIM is for those who are not yet familiar with it. An eSIM (embedded SIM) is a digital SIM card that lives inside your phone. It's not a physical chip that you insert: it's a profile that you download, just like an app, but at the deepest level of the phone. Once installed, it works just like your Telcel or AT&T Mexico SIM, but with the rate of the operator you chose.

This means you can have two active lines at the same time: your Mexican number still receives calls and messages (in case someone calls you from Mexico), and the eSIM handles your data in Europe at a local price, without the brutal surcharge of international roaming.

Does my phone have an eSIM?

Most likely, yes. Here's a quick list of the most common phones in Mexico that already have an eSIM:

• iPhone: XS, XR, 11, 12, 13, 14, 15, 16 and all Pro/Max/Mini models of those generations.
• Samsung Galaxy: S22, S23, S24 and above. Also Z Fold and Z Flip from the second generation.
• Google Pixel: Pixel 3 onwards.
• Motorola: Edge 30, Edge 40, Razr 40 and recent models.

To check on iPhone, go to Settings → General → About and look for "eSIM available." On Android, go to Settings → Connections → SIM card manager. If you see an option to add a plan, you already have an eSIM.

Why PuraSim for Europe?

There are several options on the market, but for Mexican travelers, PuraSim has specific advantages: coverage in more than 30 European countries with a single plan, 100% online activation from Mexico before your flight, Spanish language support, and prices payable in pesos or with any card. You don't need to arrive at Madrid airport to look for a physical SIM or pay the kiosk fees at the airport.

You can see all available plans in PuraSim's Europe eSIM collection. If you also travel through Latin America before or after, we have specific plans in the Latin America eSIM collection.

How much does internet cost in Europe for a Mexican traveler?

This is where it hurts the most if you don't arrive prepared. Let's compare the three options a Mexican traveler has for data in Europe:

Option 1: Telcel or AT&T Mexico Roaming (the most expensive)

Telcel offers international roaming packages that cost around 200–400 MXN per day for limited data (typically 500 MB or 1 GB daily). AT&T Mexico has similar options. For a 10-day trip, you're looking at 2,000–4,000 MXN just for data, with a speed that is usually throttled after the first few megabytes. The service exists and works, but at that price, it doesn't make much sense when there are alternatives three or four times cheaper.

Option 2: Local SIM at the European airport

Arriving in Madrid, Paris, or Rome and buying a local SIM is a valid option. A Vodafone Spain or Orange France SIM with 15–20 GB usually costs between 15 and 25 EUR (between 270 and 450 MXN at the current exchange rate of ~18 MXN per euro). The problem: you have to remove your Mexican SIM to use it, which means your Mexican number will lose coverage, and if you travel to several European countries, a SIM from one country may not work as well in the others.

Option 3: PuraSim Europe eSIM (the smartest)

With a pan-European eSIM from PuraSim, you pay for a single plan that gives you data in all the countries on your itinerary. Indicative prices are:

• 3 GB for 30 days: ~10 EUR (~180 MXN) — ideal for short stays or travelers who use hotel WiFi.
• 10 GB for 30 days: ~18 EUR (~324 MXN) — enough for most 7–14 day trips.
• 20 GB for 30 days: ~28 EUR (~504 MXN) — for those who work remotely or make many video calls.
• 50 GB for 30 days: ~45 EUR (~810 MXN) — for intensive travelers or those staying more than three weeks.

Compare: 10 days of Telcel roaming can easily cost you 3,000 MXN. A 10 GB plan with an eSIM costs less than 325 MXN. The difference is almost tenfold. And you don't lose your Mexican number.

The most visited European destinations by Mexicans

According to migration and airline data, Mexicans traveling to Europe concentrate their visits in four main destinations, and almost always combine two or three countries in the same trip. Let's see what to expect in each one and why having functional internet is essential:

Spain — Mexico's favorite

Madrid and Barcelona receive more Mexicans than any other European city. The language helps, of course, but also the cultural connection and the number of direct flights. Aeroméxico operates direct flights from Mexico City (CDMX) to Madrid in approximately 11–12 hours, and there are also connecting flights from Guadalajara (GDL) via Madrid with Iberia. In Spain, you'll need internet to navigate the Madrid subway, find authentic tapas outside of tourist areas, and use urban transport apps like EMT Madrid or TMB in Barcelona.

France — Paris and beyond

Paris is a must for many Mexican travelers, but France also offers the French Riviera, the vineyards of Bordeaux, and the Alsace region. From CDMX, there are direct flights with Air France and codeshare flights with Aeroméxico. Parisian public transport (metro, RER, bus) is efficient but requires knowing the lines — here, Google Maps with downloaded offline maps is your best ally. You'll also want to look for where to exchange pesos for euros at a better exchange rate (spoiler: avoid airport kiosks).

Italy — Rome, Florence, and the Amalfi Coast

Italy is the third most popular destination. Mexicans usually arrive in Rome, tour Florence, and end up in Venice or the southern coast. Italian intercity trains are comfortable and cheap if you book them in advance through Trenitalia or Italo, but you need internet to buy tickets in real-time (the best prices sell out quickly). You also need data to book tickets for the Sistine Chapel or the Uffizi — without advance booking, you can expect to wait 2–3 hours in line.

Netherlands — Amsterdam as a hub

Many Mexicans pass through Amsterdam as a layover or as a destination in itself. KLM has direct flights from CDMX to Amsterdam Schiphol, and from there you can connect to practically all of Europe. Amsterdam is a city where cycling is king, and apps like OV-fiets for renting train bicycles or NS for national trains are indispensable.

What all these destinations have in common: they are cities where public WiFi exists but is not always reliable or secure. Having your own data plan gives you independence to browse, pay with mobility apps, and, if something goes wrong, contact your airline or travel insurance from anywhere.

How to activate your eSIM before leaving Mexico

One of the biggest advantages of the eSIM is that you can set it up from home in Mexico, without queues or paperwork. Here's the step-by-step process:

Step 1 — Purchase your plan on PuraSim

Go to purasim.com and choose the plan that best suits your trip (duration and amount of GB). Payment is made by credit or debit card, in euros or the equivalent in pesos — no foreign account needed.

Step 2 — Receive the QR code in your email

A few minutes after purchase, you will receive an email with a QR code. This QR code is your eSIM. Keep it safe — you'll need it to install. If you prefer, you can also install it directly from the PuraSim app.

Step 3 — Install the eSIM on your phone

On iPhone: Go to Settings → Cellular Data → Add Data Plan → Scan QR Code. Point the camera at the code and the profile will be installed in a few seconds.

On Android (Samsung, Pixel, etc.): Go to Settings → Connections → SIM card manager → Add mobile plan → Scan QR Code.

Installation takes less than two minutes. The system will ask you to name the plan (for example, "Europe PuraSim") to differentiate it from your Mexican SIM.

Step 4 — Configure which line uses data

Once installed, go to your phone's dual-SIM settings and set the PuraSim eSIM to handle cellular data. Keep your Telcel or AT&T Mexico SIM active for calls and SMS, but without data (this prevents accidental roaming charges).

Step 5 — Activate it when you land (or before)

You can install the eSIM weeks in advance, but data only starts running when you activate it for the first time in Europe. Some plans have a fixed start date; others activate with first use. Check your plan's terms in the confirmation email.

Tip: Download Google Maps for the cities you'll visit before getting on the plane, while you still have WiFi at home. This way, you can navigate even if you lose signal in the subway or in areas with poor coverage.

Which apps to use for traveling in Europe

Having internet in Europe is half the equation. The other half is knowing which apps will make your life easier. Here are the ones you can't miss on your phone:

Google Maps — with downloaded offline maps

Indispensable. But there's a trick few Mexicans know: you can download maps of any city to use them offline. In Google Maps, search for the city (e.g., "Madrid"), tap the name below, then the three dots (...), and select "Download offline map." It takes between 100 and 500 MB depending on the city, but it will save your life if you lose signal in the subway or in areas with poor coverage.

Omio — for intercity trains and buses

If you plan to travel between European cities by train (Paris to Amsterdam, Rome to Florence, Madrid to Barcelona), Omio is the app you need. It compares prices for trains, buses, and flights in one place, and saves your tickets in the app for offline presentation. European trains are much cheaper if you buy them weeks in advance — the same journey can cost 29 EUR or 90 EUR depending on when you buy it.

Google Translate — with Spanish to local languages

In Italy, France, and the Netherlands, not everyone speaks English (contrary to what many believe), much less Spanish. Google Translate has a camera function that translates menus and signs in real-time — you just point the camera and the app shows you the superimposed translation. Download the language packs (Italian, French, Dutch) offline before you leave.

Uber and Bolt — city transport

Uber works in most major European cities. Bolt is a European alternative (similar to DiDi in Mexico) that is usually a bit cheaper and is available in more medium-sized cities. Both work the same as in Mexico: you register your card, request a ride, and payment is automatic. This avoids language issues when negotiating with a taxi and you know the price before getting in.

XE Currency — real-time euro to peso conversion

At the beginning of your trip, converting euros to pesos in your head is slow and confusing. XE Currency gives you the real-time exchange rate and lets you make quick conversions. Especially useful in markets, European street markets, and when comparing prices between countries (for example, if the same tour costs 45 EUR in Spain and 38 EUR in Portugal).

WhatsApp — for calls from Europe to Mexico for free

With your eSIM active and data available, WhatsApp calls to Mexico are completely free. You don't have to pay long-distance fees or activate any special package. You just need WiFi or data — which you already have with your eSIM — and that's it. Much cheaper than calling directly by phone number.

Airalo / PuraSim app — eSIM management

Download the PuraSim app to monitor how many GB you have left, top up data if necessary, and access Spanish support if something goes wrong. You can also see eSIM options for other destinations from there if you extend your trip or decide to jump to another continent.

Conclusion

Traveling from Mexico to Europe is already expensive enough without overpaying for internet. Telcel or AT&T Mexico roaming can easily cost you an extra 3,000–4,000 MXN on a 10-day trip, without you realizing it until you see your statement upon returning. A PuraSim Europe eSIM solves this for a fraction of the price, without queues or visiting a physical store.

The process is simple: you buy your plan from Mexico, receive a QR code in your email, scan it in your phone's settings, and you'll have data ready for when you land in Madrid, Paris, or Rome. Your Mexican number still works for calls, and you have your own internet without relying on hotel WiFi.

Whether it's your first trip to Europe or your second, the difference between traveling with your own data and without it is huge. Not getting lost on the subway, being able to search for restaurants with good local reviews (not tourist traps), calling home on WhatsApp without extra charges, buying train tickets in advance... All of that requires internet. And with an eSIM, that internet costs less than what you'd pay for a coffee at Barajas Airport.
