An eSIM (Embedded SIM) is a digital SIM card built directly into your smartphone or device, allowing you to activate a cellular plan without inserting a physical SIM. With just a QR code, you can connect to data services in minutes.

• Users with single-SIM slot phones
• People who want to switch between multiple carriers
• Anyone who values flexibility and speed in mobile connectivity
