If you’re planning your next international trip, you’ve probably already realized that staying connected abroad can be quite a challenge. Have you considered an international eSIM as your connectivity solution?
International eSIMs offer significant advantages over traditional SIM cards. They cannot be removed if you lose your phone or if it gets stolen, giving you greater security while traveling. Additionally, you can keep two eSIMs active simultaneously and store 8 or more eSIMs on your device, giving you extraordinary flexibility to manage your connectivity based on each destination’s needs.
This technology has established itself as the best alternative to stay connected anywhere in the world, ensuring stable connectivity even in remote locations.
In this article, we’ll guide you through discovering where to buy the best eSIMs for your trip, how this technology works, the steps to activate it properly, and why it clearly outperforms expensive traditional roaming.
Do you want to travel connected without surprises on your bill? Let’s get started!
Why Buy an International eSIM Instead of Roaming
International roaming represents one of the biggest risks to your travel budget. Traditional carriers apply daily rates that change without notice, and the most surprising charges appear on your bill weeks after returning home. An international eSIM allows you to know exactly how much you will pay from the moment you purchase it.
The numbers don’t lie. Roaming can cost up to five times more than an eSIM. A 5GB plan for Europe costs approximately $20 USD with an eSIM, while roaming from Latin America can reach $90 USD for the same service. Studies confirm that eSIMs can guarantee savings of up to 80% compared to traditional roaming rates.
Instant connectivity is another key advantage. You download and activate your plan in minutes, without long waits at airport stores or desperately searching for local vendors. The process is simple: scan a QR code and connect immediately to local networks.
The flexibility of regional or global plans allows you to move freely between countries without worrying about switching cards or unexpected charges. You have full control over your usage through an app—something unthinkable with roaming, where you only discover the real cost after your trip.

Practical Guide: From Purchase to Activation
How can you make sure your international eSIM works perfectly from the start? Let’s walk you through the full process so you avoid any issues during your trip.
Before purchasing, it’s essential to correctly estimate your data needs based on your travel style. If your usage is limited to basic browsing and messaging, you’ll need 100–200 MB per day.
Do you share every moment on social media? Then you’ll need 500 MB–1 GB per day.
If you plan to make frequent video calls, consider up to 1 GB per hour.
The next step is to check your device compatibility. Go to Settings and look for “Add eSIM” or “Add mobile data plan.” Your phone must be unlocked, with no carrier restrictions. This is crucial to ensure successful activation.
Once compatibility is confirmed, choose a plan that matches your trip duration. Keep in mind that the validity period starts when you connect to a supported network or install the eSIM, depending on the provider. Unused data is lost once the plan expires, so accurate estimation is important.
For installation, we recommend doing it one or two days before your trip using a stable WiFi connection. You’ll receive a QR code by email that you must scan from your device’s mobile data settings. Once you arrive at your destination, don’t forget to enable data roaming for your eSIM line.
💡 Tip: HOLASIM makes this entire process much easier. With instant QR installation, 24/7 Spanish support, and plans starting at $17 USD, you can travel with complete peace of mind and zero technical hassle.
