What is eSIM?

An eSIM is a SIM that is embedded directly into a mobile phone device.

You can rewrite the SIM information online, eliminating the need to insert and remove it, and it functions the same as a physical SIM card.

You can complete the contract and application online and start using the service immediately.

Unlike Wi-Fi routers, there is no need to worry about picking up and returning a rental, and you can instantly obtain a comfortable communication environment at a low cost, which greatly improves convenience.

In addition, since you can use plans from multiple carriers at the same time, it is convenient when you want to use local plans when traveling, etc.
