eSIM for Mexicans Traveling to Europe — All You Need to Know

If you're traveling from Mexico to Europe, you already know that roaming with your local carrier can be a very unpleasant surprise upon your return: bills for tens or even hundreds of dollars/euros for a few days of data. There's a much smarter solution: an eSIM specifically for Europe.

In this guide, we'll explain exactly how it works, how much you can save compared to roaming with your Mexican carrier, and how to activate your PuraSim eSIM before boarding your flight.

With PuraSim, you'll have local data in Europe from the moment you land, at local prices, with no commitments and no need to change your physical SIM.

Roaming from Mexico to Europe: what it really costs

Mexican carriers offer international roaming packages for Europe, but the prices are rarely competitive. Depending on your carrier, a day of data in Europe can cost you between 15-25 USD/EUR per day.

Let's look at a real example: if your trip to Europe lasts 10 days and you use data moderately (maps, messages, social media), with traditional roaming you could pay between 150 and 250 euros/dollars just for connectivity. With a PuraSim eSIM for Europe, that same usage would cost a fraction of that.

In addition to the cost, roaming has other limitations:

• Reduced speed often to 3G or even 2G
• Very low daily data cap before your speed is cut
• You need to activate the service before leaving (and pay for it even if you don't use it)

A PuraSim eSIM eliminates all these problems: you pay once for the GBs you need, you get real 4G/5G speed, and you activate it only when you need it.

How an eSIM for Europe works

An eSIM (embedded SIM) is a digital SIM that lives inside your phone. There's no physical card to insert: you download the carrier's profile using a QR code and you're good to go. Your phone can have several eSIMs installed simultaneously and switch between them in seconds.

For travelers from Mexico to Europe, the process is as follows:

1. Purchase your data plan on purasim.com before leaving
2. Receive the QR code by email
3. Install the eSIM on your phone from home (in 5 minutes)
4. Upon landing in Europe, activate the eSIM and you'll have local data
5. Your Mexican SIM will continue to work for receiving calls and SMS

No need to go to any store. No need to wait in line. No need to look for a phone shop when you arrive at the European airport. You arrive and you already have internet working.

How many GB do you need for Europe?

For a trip from Mexico to Europe, our recommendation is 15-20 GB for 14 days. This is enough for most common uses: Google Maps throughout the day, WhatsApp with family and friends in Mexico, Instagram, occasional searches, and some video calls.

Breakdown of typical daily consumption:

• Google Maps actively navigating: ~150 MB/day
• WhatsApp with messages and photos: ~100 MB/day
• Instagram and social media (no video): ~300 MB/day
• Searches and websites: ~100 MB/day
• Estimated total: 600-700 MB/day for moderate use

If you plan to work remotely, make frequent video calls, or upload real-time content, consider a higher plan. PuraSim plans offer top-ups if you run out, so you can always extend.

Tip: Telcel or AT&T Mexico roaming in Europe can cost more than 20 USD per day; a European eSIM costs a fraction of that

How to activate your eSIM before your flight

The best thing about PuraSim eSIMs is that you can have it ready before leaving Mexico. The installation process takes about 5 minutes and you only need WiFi:

1. Check compatibility: make sure your phone supports eSIM (iPhone XS or higher, Samsung Galaxy S20+, Google Pixel 3+ and many more).
2. Purchase your plan on purasim.com. Select the Europe destination and the GB plan you need.
3. Install the eSIM: open the email with the QR code and go to your phone's Settings to scan the code and download the profile.
4. Configure the eSIM: give it a recognizable name (e.g., "PuraSim Europe") and make sure it's configured for data but NOT for calls or SMS (you keep those on your Mexican SIM).
5. Activate it upon arrival: on the plane, you can have the eSIM installed but inactive. Upon landing in Europe, go to Settings → Mobile Data and activate the PuraSim eSIM.

In less than 5 minutes after landing, you'll have full data in Europe without having left the airport.

Tips for travelers from Mexico to Europe

Beyond connectivity, here are some specific tips for travelers from Mexico:

• Download everything before leaving: offline maps of Madrid, Paris, Rome, and Amsterdam in Google Maps, Spotify playlists, Netflix episodes for the flight. In the first few hours of your flight, you won't have data.
• Notify your bank: many Mexican banks block transactions in Europe for security reasons. Inform them of your trip to avoid having your card blocked at the most inconvenient time.
• WhatsApp will work perfectly: with the eSIM active, you can call and talk to family and friends in Mexico without additional cost for international calls.
• Save documents offline: scan your passport, travel insurance, and bookings and save them on your mobile. If there's a moment without data, you'll still have access.

And remember: Telcel or AT&T Mexico roaming in Europe can cost more than 20 USD per day; a European eSIM costs a fraction of that

With PuraSim connected, your trip from Mexico to Europe starts smoothly from the very first moment.
