What an eSIM is, in plain language
No plastic card, no shop queue. A short explanation of how a travel eSIM works on your phone.

An eSIM is a SIM card built into your phone. Instead of inserting a plastic card, you install a mobile plan onto the phone — usually by scanning a QR code — and switch it on when you want to use it.
How installation works
After purchase, your order page shows a QR code plus a manual activation code and SM-DP+ address for phones that prefer typed entry. You scan the code from your phone's mobile settings while connected to Wi-Fi, and the plan is added as an extra line.
Does my phone support it?
Your device needs eSIM support and must be carrier-unlocked. Recent iPhone, Samsung Galaxy and Google Pixel models generally support eSIM; if you are unsure whether your device is unlocked, ask your carrier.
What changes when you travel
Set the eSIM as the line used for mobile data and turn on data roaming for that line where required. Your usual SIM stays in the phone, so calls and messages on your normal number keep working as they do at home.
