Why use a free eSIM in Taiwan?

A travel eSIM gives you mobile data without removing your physical SIM card. In Taiwan, that means you can open maps, messages, hotel details, tickets and travel apps without waiting for airport Wi-Fi or paying daily roaming fees.

Install your Taiwan eSIM before departure so you can open maps, messages, transport apps, and hotel details as soon as you arrive.
