Everything you need to know about RoamReady eSIMs. Can't find your answer? Contact our support team.
An eSIM (embedded SIM) is a digital SIM card built directly into your device. Instead of inserting a physical card, you activate a data plan by scanning a QR code or entering an activation code. Once activated, your device connects to the local network just like a regular SIM card — but without any plastic or waiting.
