An eSIM (embedded SIM) is a digital mobile profile you download to your phone — usually via QR code — instead of inserting a plastic chip.
eSIM vs physical SIM
Physical SIMs must be swapped or bought locally. eSIM lets you add a second data line for travel while keeping your home number for calls and WhatsApp.
How to get started
Check that your phone supports eSIM (Settings → Add eSIM). Then browse our travel catalog and pick a country plan.
