What is eSIM?

An eSIM is a programmable SIM card that is embedded directly into a device. Unlike traditional SIM cards, it cannot be physically inserted, removed, or transferred to another device.

An eSIM QR code contains a digital SIM profile that allows you to access a cellular plan without inserting a physical SIM card. Depending on your smartphone, eSIM technology also enables you to use up to two phone numbers simultaneously.

How to check eSIM compatibility: You can verify your device's eSIM compatibility by dialing *#06# to display your IMEI number, then confirm that your device supports eSIM functionality.

Real-world Example: João lives in Brazil and plans to visit Canada for 3 months. He doesn't want to wait for the SIM card shipping process, which could take 10-15 business days for an international package to arrive from Canada. João is looking for an alternative that could save him both time and money.

João decides to proceed with eSIM activation through PhoneBox. He receives a QR code via his registered email address, scans the code, and activates his service immediately with no shipping required.
