An eSIM is a digital SIM card built into most modern phones. Its main function for travelers is to let you purchase an eSIM package and connect to the internet abroad without handling or swapping a physical SIM.

Think of it like a traditional SIM, but invisible. You activate it digitally, usually by scanning a QR code sent to your email.

Key benefits for travelers:

• Instant connection: You purchase your eSIM package from home and have an internet connection as soon as you land.
• Keep your WhatsApp: You retain your existing phone number.
• Goodbye to expensive roaming: You avoid unwanted roaming charges from your carrier.
• Security and convenience: There's no risk of losing your primary SIM card.

For more details, see our complete guide on what an eSIM is here.

It works 100% digitally. First, you install the eSIM on your phone by scanning a QR code we send you after purchase. Upon landing at your destination, the eSIM activates and automatically connects to the best local carrier to give you instant internet access. Here's how it works in 2 simple steps:

Step 1: Installation (before traveling)

• Purchase your eSIM package for your destination on our website.
• You'll receive a QR code by email, scan it in your phone's settings to install the eSIM. We recommend doing this one or two days before departure.

Step 2: Connection (upon landing)

• When you arrive, simply enable the eSIM line in your phone's mobile settings.
• Your phone will automatically search for and register on the local network with the best signal (e.g., Vodafone in Spain, KDDI in Japan), with no extra steps required.

The magic behind the connection: Our eSIM acts like a "passport" for mobile networks. It isn't tied to a single operator. Instead, we partner with the top carriers in each country. That's why we provide you the best available coverage and speeds.

It's very simple! To use our eSIM, your phone only needs to meet two requirements: be eSIM-compatible and be unlocked to work with any carrier. Here's how to check both:

First Requirement: eSIM-Compatible Phone

Most phones manufactured from 2019 onward include eSIM technology.

Some popular devices that are compatible:

• Apple: iPhone XR, XS and later (including all iPhone 11, 12, 13, 14, 15 and 16 models)
• Samsung: Galaxy S20, Note 20, Fold, Flip and later
• Google: Pixel 3 and later

Verify if your device is compatible here: All eSIM compatible phones

Second Requirement: Unlocked Phone

"Unlocked" means your phone isn't tied by contract to a single carrier (e.g., Telcel, AT&T, Movistar) and can use SIMs or eSIMs from other providers.

Quick check:

• On iPhone: Go to Settings > General > About. Scroll to "Carrier Lock." If it says "No SIM restrictions," it's unlocked! If it says something else, it probably has a restriction.
• On Android: The surest way is to insert a friend's SIM from a different carrier, if your phone recognizes it and shows signal, it's unlocked. You can also call your carrier and ask.

For more details, see our complete guide on how to check if your phone is carrier unlocked.

Once you've confirmed both, you're ready! You can purchase and install your DatosdeViaje eSIM package from anywhere in the world.

Scan the QR at home, then activate your eSIM upon landing and enable data roaming to connect instantly.

Phase 1: Installation (do this at home, on Wi-Fi)

1. Find the email: open the message with your QR code.
2. Open Settings: go to Settings > Mobile Networks (or Cellular Data) > Add eSIM.
3. Scan the code: point your camera at the QR code.
4. Follow the prompts: add the eSIM package. Keep your DatosdeViaje eSIM "off" until you travel.

Phase 2: Activation (do this upon landing)

1. Open Settings: go again to Settings > Mobile Networks.
2. Turn on your eSIM: select your DatosdeViaje eSIM and activate it.
3. Disable your primary line: turn off your physical SIM or main line to avoid accidental charges from your original carrier.
4. Enable data roaming: make sure data roaming is turned on for your DatosdeViaje eSIM.

Quick fix: If your eSIM doesn't connect on arrival, first check that data roaming is enabled.

For more details, see our full activation guide here

You can get a quick estimate on your phone's settings or an exact figure in your "My eSIM" portal, accessed via the email we sent you.

Option 1: In the "My eSIM" portal (exact data)

Open the email with your QR code and click the green button labeled "Consumption." You'll enter a dashboard showing remaining data, your package's validity, and other details.

Option 2: On your phone (quick estimate)

• iPhone: Go to Settings > Cellular Data (or Mobile Networks) and scroll to see usage next to your eSIM's name.
• Android: Go to Settings > Network & Internet > Data Usage to view consumption for each SIM.

You can add more data to your eSIM in two ways without having to install a new eSIM: use the link you received by email or do it from your account on our website.

Option 1: Using the link in your email

1. Find the email: open the message containing your QR code.
2. Access the portal: click the green button labeled "Consumption."
3. Start the top-up: click "Top-up eSIM."
4. Select your package and confirm the purchase.

Option 2: If you have a user account

1. Log in: go to and click "My Account" (or "My eSIM").
2. Locate your active eSIM.
3. Click "Top-up eSIM."
4. Select your package and confirm the purchase.

Key point: In both cases, the new data is added automatically to your eSIM, no installation is required.

Our eSIMs are designed for mobile data only, so they don't include a phone number for traditional calls. However, you can make voice or video calls using internet-based apps, consuming data from your eSIM package.

Option 1: App-based calls (recommended):

Use WhatsApp, FaceTime, Zoom, Telegram, Facebook Messenger, etc.

Option 2: Traditional calls:

For calls to landlines or mobile numbers, you must use your primary line (physical SIM or primary eSIM).

Important: Your primary line must be turned on and may incur roaming charges. Check fees with your carrier before placing a call.

Your package's validity starts the moment your eSIM first connects to the network of any country included in your package. It does not begin when you purchase or install the eSIM at home, giving you full flexibility to prepare in advance.

To make it clearer, here's a practical example:

• Monday, July 1: You purchase a 10-day unlimited data package for travel in Spain. Validity has not started yet.
• Tuesday, July 2: You install the eSIM on your phone at home. Validity still hasn't started.
• Friday, July 5 at 9:00: You land in Madrid, enable your eSIM line in settings, and it connects to Vodafone's network. Now the 10-day validity begins!
• Monday, July 15 at 9:00: Your package will expire exactly 10 days after that first connection.

Key point: You can buy and install your eSIM package as early as you like, validity only starts when your trip truly begins.

The ideal time is one to two days before your trip so you can install it at home over a stable Wi-Fi connection. However, you can also buy it last-minute before your flight, or even after you land if you have access to Wi-Fi. Here are the most common scenarios:

Scenario 1: Ideal option (a few days before)

• When: 1–3 days before your flight.
• Why: You can install the eSIM without rushing, confirm everything works, and contact support if needed. You'll travel worry-free knowing you only need to activate it upon landing.

Scenario 2: Last-minute purchase (before traveling)

• When: The same day of your trip, even at the airport before boarding.
• Why: If you forgot, as long as you have Wi-Fi, you can buy and install your eSIM package in under 5 minutes and be ready before takeoff.

Scenario 3: Purchase at destination (after landing)

• When: You're already at your destination and need internet.
• How to do it: Connect to airport Wi-Fi or use the Wi-Fi at your hotel or accommodation. Then Visit our website, purchase your eSIM package, and follow the installation steps sent by email.

Yes, absolutely! All our eSIM packages let you share your mobile data with other devices (laptops, tablets, or other phones) by enabling the "Personal Hotspot" or "Mobile Hotspot" feature on your phone.

Important tips and considerations:

• Data consumption: Connecting more devices will use up your package faster.
• Phone battery: Using your phone as a hotspot drains the battery, bring a power bank if you plan to use it for long periods.
• Use cases: Ideal for giving internet to family devices, working on your laptop in a café, or letting your kids use a tablet on a road trip.

Gigabyte packages: You always browse at the maximum available speed (4G/LTE/5G).

Unlimited packages: We apply a Fair Usage Policy (FUP) after high daily consumption to guarantee service quality.

What is the Fair Usage Policy (FUP)?

It's an industry-standard rule that keeps the network stable for all users.

How the FUP works:

• Daily high-speed allowance: You typically get 1 GB – 1.5 GB per day at unrestricted maximum speed (depending on the package).
• After the daily limit: Speeds are throttled, but you retain unlimited data for essential use.
• Daily reset: The high-speed period resets every 24 hours.

Our recommendation: Choose a data-by-gigabyte package if you want guaranteed maximum speeds.

The process is instant. From the moment you purchase and install the eSIM at home (which usually takes under 5 minutes) to the moment you connect upon arrival at your destination. Once you land, just turn on the eSIM in your settings and the connection is established immediately.

What if it doesn't connect right away?

Although rare, the fix is usually very simple:

1. Check the key setting: Make sure Data Roaming is ENABLED for your eSIM line. This solves the issue 99% of the time.
2. Get help if needed: If the problem persists, visit our Troubleshooting page here or message us on WhatsApp and we'll guide you step by step.

For a traveler, the main advantages of an eSIM are instant convenience, cost savings, and security. It lets you land at your destination and have internet immediately, no waiting in line for a physical SIM or risking losing your own.

Here are the key benefits, explained in detail:

1. Instant connection

• Physical SIM: You arrive in a new country and can't call an Uber, notify your family, or use your maps until you find a shop and buy a SIM.
• eSIM: You install it at home before departure. Upon landing, you turn it on and you're already connected. Zero stress.

2. Keep your WhatsApp number

• Physical SIM: You must remove your primary SIM, interrupting chats and calls.
• eSIM: Your primary SIM stays in your phone. You keep using your number and WhatsApp as usual, while the eSIM handles data only.

3. 100% digital process

• Physical SIM: Involves finding a store, dealing with language barriers, and sometimes showing your passport.
• eSIM: You purchase and install in under 5 minutes on our website, wherever and whenever you want.

Your eSIM is active and ready if you can browse the internet or use apps like WhatsApp. Follow these steps to confirm:

1. Check the signal: Look at the network indicator (the signal bars) at the top of your screen. If you see "4G," "LTE," or "5G" next to the bars, your eSIM is detecting data.
2. Test the connection: Open your browser or Google Maps. Send a message in WhatsApp or open any app that uses data. If it loads, your eSIM is working!
3. Troubleshooting checklist (if you have no connection):

• Mobile Data: In Settings, make sure your DatosdeViaje eSIM is selected as the data line.
• Data Roaming: Ensure Data Roaming is enabled for your eSIM (it won't incur extra charges).
• Date & Time: Incorrect settings can block the connection—set them to automatic.

4. Get support: If it still doesn't work, visit our troubleshooting page here or message us on WhatsApp at +52 81 3244 0968.

Deactivate the eSIM: Go to Settings and turn off the eSIM. It will stay saved on your phone so you can reactivate it on your next trip without reinstalling, just top-up data.

Delete the eSIM: Remove the eSIM only if you're sure you won't use it again. This action is permanent. In the future, if you need another eSIM, you'll have to install a new one.

In summary: Deactivate it to keep it ready and enjoy maximum convenience, delete it only if you don't plan to reuse it.
