What is an eSIM?
An eSIM (embedded SIM) is a tiny, programmable chip embedded directly into a device, such as a smartphone, tablet, or smartwatch. It takes the place of the traditional removable SIM card, eliminating the need for a physical card to connect to a cellular network.
How does it work?
Instead of storing your network operator information on a physical card, an eSIM stores it electronically. You can activate or switch network operators remotely by downloading a profile from your carrier. This can be done through your device's settings or a dedicated app.
Benefits of eSIM:
- Convenience: No more swapping tiny SIM cards when switching phones or operators.
- Security: eSIMs are soldered onto the device's motherboard, making them more difficult to lose or steal compared to physical cards.
- Flexibility: You can store multiple eSIM profiles on a single device and easily switch between them. This is ideal for travelers who want to use local SIM cards or for businesses with employees who need to use different lines.
- Global: eSIM is a global standard, so it works with compatible devices and networks worldwide.
- Compact: eSIMs are much smaller than traditional SIM cards, freeing up space inside devices for other components.
