An eSIM (embedded SIM) is a programmable chip permanently integrated into your device. Unlike a physical SIM card, it doesn't need to be swapped — carrier profiles are downloaded and installed remotely.
For European travelers, this means you can purchase a data plan online, receive a QR code, and be connected within minutes — without visiting a store or touching any hardware.
One eSIM can store multiple profiles simultaneously. Keep your home carrier active for calls while using a separate travel plan for data — all on one device.
