How eSIM Works for Travel
The complete guide to using eSIM for international travel. Learn how to set up, activate, and get the most out of your travel eSIM.
What is eSIM?
An eSIM (embedded SIM) is a digital SIM card built into your smartphone. Unlike physical SIM cards that you insert into your phone, an eSIM can be programmed remotely with carrier information.
For travelers, this means you can purchase a data plan online, scan a QR code, and instantly have local data in any country — no need to find a SIM shop or swap tiny cards.
eSIM vs Physical SIM
How to Set Up eSIM (4 Easy Steps)
Check Device Compatibility
Ensure your phone supports eSIM. Most phones from 2019 onwards support eSIM, but carrier-locked phones may not.
Pro Tip: Go to Settings > General > About > look for EID number (iPhone) or Settings > Connections > SIM manager (Android)
Purchase an eSIM Plan
Choose a plan based on your destination, data needs, and trip duration. Plans are delivered instantly via email.
Pro Tip: Buy your eSIM before departure - you can install it anytime but only activate when you arrive.
Scan the QR Code
Open your camera app and scan the QR code from the email. Your phone will prompt you to install the eSIM.
Pro Tip: Need WiFi to scan and install. Do this at home or hotel before heading out.
Activate When Ready
Turn on your eSIM data when you arrive at your destination. Your phone can have multiple eSIMs installed.
Pro Tip: Label your eSIMs clearly (e.g., "Europe Trip 2025") to manage multiple plans.
