An eSIM (embedded SIM) is a digital SIM built directly into your device. It allows you to activate a mobile plan without inserting a physical SIM card.
eSIMs make it easier to switch carriers, manage multiple lines, and stay connected while travelling globally without visiting a store or waiting for physical delivery.
To activate your eSIM:
1. Purchase an eSIM plan from One Telecom.
2. Open the email or dashboard to access your QR code.
3. On your device, go to Settings → Mobile/Cellular → Add eSIM.
4. Scan the QR code and follow the instructions.
Activation works worldwide, provided your device is connected to WiFi or mobile data.
