How to activate an eSIM in Europe?
eSIM technology in Europe is revolutionizing the way we use our mobile devices. An eSIM, or virtual or integrated SIM, is a digital version of the traditional SIM card that allows users to activate a data plan without the need for a physical card. This makes it easier to manage multiple carriers and plans on a single device.

Steps to activate an eSIM in Europe
Activating an eSIM in Europe is a simple process, but it may vary slightly depending on the carrier and device. Here are the general steps:
Step 1: Check your device's compatibility
Before proceeding, make sure your device is compatible with eSIM technology. Most modern smartphones, such as the latest iPhone models and some Android phones, already support eSIM.
Step 2: Purchase your eSIM
At TuSim Travel, you can choose from a variety of data plans that suit your needs, from basic 2GB plans for short trips to unlimited plans for extended stays. Once you have made the purchase, you will receive your QR code 24 to 48 hours before the date indicated in the purchase. This code is essential for activating your international eSIM on your mobile device.
Step 3: Scan the QR code
- iPhone: go to Settings > Cellular > Add eSIM and scan the provided QR code.
- Android: open the Settings > Network & Internet > Mobile network > Add carrier app and scan the QR code.
Step 4: Configure your data plan
After scanning the QR code, follow the on-screen instructions to configure your data plan. This may include selecting your phone number and adjusting data preferences.
Step 5: Activate the eSIM
Once configured, your device should automatically activate the international eSIM. You may need to restart your phone to complete the process.

eSIM activation times in Europe
When you purchase your eSIM, you can determine the activation date, which we will set one day before your trip or specific date to ensure your service is ready to use upon arrival at your destination. To avoid any inconvenience, it is recommended to install the eSIM (scan the QR) on the day of the trip. This ensures that the activation aligns perfectly with your itinerary and that your data plan starts counting from the first day of use.
If your flight plan changes, it is crucial that you notify us at least three days in advance. This will allow us to adjust the activation date of your international eSIM and ensure your data plan is available at the correct time.
Procedure in case of changes
- Communication: contact our customer service through the channels (email, phone, etc.).
- Required information: provide the details of your new itinerary, including the new travel dates.
- Activation confirmation: you will receive confirmation that your eSIM activation has been rescheduled according to the new dates provided.
Why do we lose coverage and need an eSIM?
Planning a trip can be exciting and enriching, but it also presents technical challenges, such as a lack of coverage from your usual mobile operator, here's why this happens:
Local operator limitations:
Your mobile operator may not have roaming agreements with operators in the country you are visiting. This means that you will not be able to use your usual mobile network and, therefore, will not have access to call, message, or mobile data services.
High roaming costs:
If your operator offers roaming services, these are usually extremely expensive. Additional costs for data usage, calls, and messages can accumulate quickly, making mobile phone use prohibitively expensive.
Different frequencies and bands:
Not all operators use the same frequencies and bands for their mobile services. Your device may not be compatible with the frequencies used by operators in the country you are visiting, resulting in a lack of coverage.
