What is an eSIM?
An eSIM is a digital SIM that lets you add a mobile plan to your phone without a physical card. It is the simplest way to get data when you travel.
eSIM in a nutshell
“eSIM” stands for embedded SIM. The SIM is built into your phone as a chip, and the plan is stored digitally. Instead of buying a plastic card and swapping it into a tray, you scan a QR code or tap an install button, and your phone downloads the plan.
How an eSIM works
- You choose a plan for your destination and complete your purchase.
- You receive an activation profile, usually a QR code and manual details.
- Your phone installs the profile over Wi-Fi and adds a new cellular line.
- You select the eSIM for mobile data and connect to a local network.
Why travelers use eSIM
- Get online on arrival. Install before you fly, then switch on when you land.
- Skip roaming surprises with a plan that has a fixed price and validity.
- Keep your home number for calls and texts while the eSIM handles data.
- No shop visits, ID queues or tiny cards to lose.
- Cover one country, a region or several destinations with a single plan.
What you need
- A phone that supports eSIM. See our compatible devices guide.
- A phone that is not locked to one carrier.
- A Wi-Fi or data connection to download the plan.
