In today’s hyper-connected world, mobile technology is constantly evolving, and one of the most significant advancements in recent years is the introduction of eSIM technology. Unlike traditional physical SIM cards, an eSIM (embedded SIM) is built directly into your device, enabling users to activate and manage cellular plans digitally—often by scanning a QR code or using a carrier’s mobile app.
For users in India, eSIM technology offers enhanced convenience, security, and flexibility. However, it also has certain drawbacks, including limited device compatibility and challenges in switching between phones. This article explores everything you need to know about using an eSIM in India, its benefits, drawbacks, and how to set it up on both Android and iPhone devices.
What is an eSIM and How Does it Work?
An eSIM (embedded SIM) functions like a traditional SIM card but is permanently embedded into a smartphone, tablet, or wearable device. Users can activate an eSIM by downloading a digital profile provided by their carrier instead of physically inserting a SIM card.
Key Features of an eSIM:
- Eliminates the need for a physical SIM card.
- Supports multiple carrier profiles on a single device.
- Allows users to switch between mobile operators seamlessly.
- Offers improved security as it cannot be removed or cloned easily.
- Enables a more compact device design by removing the SIM tray.
