What Is an International eSIM, and How Do eSIMs Work for Travel?

An international eSIM is an easy, cost-effective way to stay connected while traveling, without the hassle of physical SIM cards or high roaming fees. If you’re wondering how eSIMs work for travel? They function like local SIM cards, but with the convenience of keeping your regular number. Keep reading to learn more about how international data eSIMs can simplify your travels.

How Does an International eSIM Work?

An international data eSIM lets travelers activate a mobile plan directly on their phone, avoiding the need for a physical SIM card. With apps like Holafly, users can easily purchase local plans, connect to networks at lower costs, and even keep their regular number with Dual SIM support. Even without Dual SIM, the eSIM can be used for data-only services like WhatsApp or Messenger.

You can also store multiple eSIM profiles, switching between plans for multiple destinations. This offers a flexible, cost-effective solution for staying connected abroad without the hassle of swapping SIM cards or high roaming fees.

Local SIM vs. International eSIM

• Local SIM cards work only in one country, while international eSIMs provide coverage across multiple countries.
• Local SIM cards require physical swapping, whereas international eSIMs are activated digitally.
• Buying a local SIM card requires going to a store, while an international eSIM can be purchased online from home, saving time.
• Local SIM cards are typically cheaper in-country, while international eSIMs may have higher costs but avoid roaming fees.
• Local SIM cards are limited to one slot unless your phone supports Dual SIM, while international eSIMs can work alongside your regular SIM in Dual SIM devices.

To keep in mind

• Make sure your device is eSIM-compatible and unlock. 
• Check the coverage in the countries you'll be visiting. 
• Install the eSIM before traveling to avoid any issues. 
• If your phone supports it, use both eSIM and physical SIM simultaneously. 
• Review the plan's duration and extension options.
