Why Get an eSIM for Taiwan?
- Online the moment you land. Order a ride or check the MRT route from Taoyuan Airport before you reach passport control.
- No SIM counter queue. Airport SIM desks are convenient but can be busy after long-haul arrivals, and they ask for your passport.
- Keep your number for messages and bank codes from home.
- Usually far cheaper than roaming with your home carrier.
How to Choose a Taiwan eSIM
Trip length
Pick a plan that covers your whole stay plus a spare day for flight times. egoViet plans can't be topped up, so it is better to size up than to run short. If your high-speed data does run out, you stay online at a basic speed of around 128 kbps, enough for messaging.
How much data you use
Maps, messages, and MRT apps use little data. Night-market food videos, video calls, and hotspotting a laptop use much more. Here is a guide to how much data you need when you travel.
Where you are going
For a Taiwan-only trip, a Taiwan eSIM is the best value. If you are combining Taipei with Japan, Korea, Hong Kong, or Southeast Asia, look at the Asia eSIM below.

Visiting More of Asia? The Asia eSIM
Taiwan pairs well with Japan, South Korea, Hong Kong, or a Southeast Asia loop. The Asia eSIM covers Taiwan along with these destinations on a single plan, so you don't need a new eSIM at every border. For a Taiwan-only trip, the Taiwan eSIM is cheaper.
Here is how country and regional eSIMs compare.

Tips for Staying Connected in Taiwan
- Get an EasyCard for the MRT, buses, and convenience stores, and use Google Maps or the local transit apps for live arrival times.
- Save offline maps for the mountains. Signal can drop in parts of Taroko Gorge, Alishan, and on high trails.
- Use LINE. It is the most popular messaging app in Taiwan, and many guesthouses and tour operators use it.
- Watch the typhoon season. From roughly July to October, keep an eye on weather alerts and transport updates.
- Need to call? egoViet eSIMs are data-only, so use LINE, WhatsApp, or FaceTime. Here is how calling works with a data-only eSIM.
FAQs: eSIMs for Taiwan
What is the best eSIM for Taiwan?

Does mobile data work across Taiwan?
Coverage is strong in cities and along the main routes. It can be weaker in deep gorges and high mountains, so download offline maps before hiking.
