Frequently asked questions

Korean passport holders can enter Taiwan visa-free for 90 days for tourism (as of 2026). An online arrival card may be required, which is easy to complete with your Roamis eSIM already online. Confirm current rules before you fly.

Validity starts when you install and connect in Taiwan — not when you buy. Set it up before you fly and it begins counting from your first connection on arrival.

Yes, you can share your connection to a laptop or another device. Heavy tethering may be subject to the fair-use terms shown on the plan.

Coverage is good along the HSR line and at most attractions. Mountain areas like Alishan and Taroko Gorge can be weak, so we recommend downloading offline maps in advance.

No. The eSIM runs alongside your existing SIM, so you keep your number for calls and texts while using Roamis for data.
