What an eSIM is and why use one

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 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.

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 data 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.
