An eSIM, or Embedded Subscriber Identity Module, is a digital version of the traditional physical SIM card you might be used to. Instead of a small plastic chip that you insert into your phone, an eSIM is a tiny chip that's already built into your device (like a smartphone, tablet, or smartwatch) and can be programmed remotely.

GitSim utilizes eSIM technology to provide you with flexible and convenient mobile data plans, especially when you travel.

How is an eSIM different from a Physical SIM?

Feature	Physical SIM Card	eSIM (Embedded SIM)
Form Factor	A small, removable plastic chip.	A small chip embedded directly into the device's hardware.
Activation	Manually inserted into a SIM slot.	Activated digitally, often by scanning a QR code or via an app.
Switching	Requires physically swapping cards.	Can be switched or updated via software settings.
Multiple Plans	Typically one plan per physical SIM slot.	Can store multiple carrier profiles (though usually only one or two can be active at a time).

Key Benefits of Using an eSIM

• Convenience: No need to find a physical store to buy a SIM card or wait for one to be mailed. You can often purchase and activate an eSIM plan online within minutes.
• Flexibility: Easily switch between different mobile carriers or data plans without needing to swap physical SIM cards. This is especially useful for travelers who want to use local plans in different countries.
• Multiple Numbers: On supported devices, you can have multiple eSIM profiles stored and switch between them, or even use one eSIM alongside a physical SIM for two active numbers (e.g., one for personal, one for business, or one for home and one for travel).
• Space Saving: For device manufacturers, not needing a physical SIM tray can free up space for other components or allow for sleeker device designs.
• More Secure: An eSIM cannot be physically removed if your device is lost or stolen, making it slightly harder for someone to misuse your SIM.
