If you’re planning to travel abroad, an eSIM for international travel is the easiest way to stay connected without swapping physical SIM cards. It lets you download a data plan instantly and switch networks in seconds, perfect for travelers who move between countries.

What is an eSIM and How It Works

An eSIM (embedded SIM) is a digital SIM built directly into your phone or device. Instead of inserting a physical card, you activate mobile plans digitally through a QR code or an app.

When traveling internationally, eSIMs connect to local networks through global providers such as Eskimo. You can choose a plan for your destination, activate it before departure, and land ready to use mobile data.

Benefits of Using eSIM for International Travel

  • Instant activation - no need to visit a store abroad.
  • Multiple plans on one phone - perfect for frequent travelers.
  • No roaming charges - connect directly to local carriers.
  • Environmentally friendly - no plastic SIMs.

How To Get an eSIM

Getting an eSIM is simple and takes less than five minutes. Follow these steps to get connected before your trip:

  1. Check compatibility - Make sure your device supports eSIM. Most modern iPhones and Android phones include this feature by default.
  2. Choose a provider - You can buy eSIM plans from Eskimo. Eskimo offers flexible regional and global plans for travelers.
  3. Select your destination - Pick a country or region, such as Japan eSIM, and choose a plan that fits your data needs and trip length.
  4. Activate your plan - Once you’ve completed the purchase, scan the QR code or follow the in-app setup steps to install your eSIM instantly.
  5. Switch networks abroad - When you land, your phone will automatically connect to a supported local network. No manual configuration needed.

Tip: If you’re planning to visit another country, simply buy a new plan, no need to reinstall your eSIM.

An eSIM for international travel makes staying connected simple, affordable, and hassle-free. With Eskimo, you can manage global plans from one account, avoid roaming fees, and enjoy seamless coverage wherever you go.

This makes eSIMs ideal for digital nomads, frequent flyers, and anyone who needs data coverage across multiple countries.
