An eSIM, or embedded SIM, is a digital version of the traditional SIM card used in mobile phones and other devices to facilitate communication. It is built directly into the device, eliminating the need for users to insert a physical SIM card. Here are the key aspects that define how eSIM works and its purpose:
- Digital Management: Users can activate and switch mobile operators or plans without the need to replace a physical SIM card.
- Greater Convenience: eSIM makes it easier to switch between operators and plans, and simplifies the process during travel, allowing for easy switching to local operators.
- Space Saving: Since the eSIM is embedded directly in the device, it frees up space for other components, which is particularly important for small devices like smartwatches.
- Enhanced Security: Losing or having a physical SIM card stolen can be a security issue. eSIM reduces this risk as it cannot be physically removed from the device.
- Multi-Profile Capability: Some devices with eSIM can store multiple operator profiles, allowing users to easily switch between different numbers or plans.
eSIM is gaining popularity in smartphones, tablets, smartwatches, and other devices due to its advantages in flexibility, convenience, and efficient use of space.
