What is eSiM ?

With an eSIM, a SIM card built into a smartphone, there is no need to insert or remove a physical SIM card as with conventional methods. Communication is possible with just a simple setup.

Preparing for an overseas trip involves a lot of things, like purchasing a passport, plane ticket, and local currency. A smartphone is essential for local research and using map apps. "Should I rent a Wi-Fi router?" "Should I buy a prepaid SIM card for overseas use?" Overseas eSIM services eliminate the hassle and allow you to use your existing smartphone.
