An eSIM, or embedded SIM, is a SIM card that is embedded inside a device and is not removable. It stores the necessary information to connect to a mobile network, just like a physical SIM card.

What is a physical SIM?

A physical SIM is a small plastic card that is inserted into a mobile device to connect to a mobile network. It stores the necessary information to connect to a mobile network, such as the subscriber's phone number and carrier plan.

What are the advantages of an eSIM over a physical SIM?

One advantage of an eSIM is that it does not require a physical card to be inserted into a device, making it more convenient for users who frequently switch between carriers or devices. It also allows for more flexibility in terms of carrier plans and can save space in the device by eliminating the need for a SIM card slot.

What are the disadvantages of an eSIM compared to a physical SIM?

One disadvantage of an eSIM is that it may not be supported by all devices or carriers, limiting its availability. It also may not be as secure as a physical SIM, as it can be remotely hacked or copied, whereas a physical SIM is protected by the physical presence of the card.
