Taiwan eSIM

Staying connected in Taiwan

Taiwan is one of the most connected places you can travel, and the quickest way to get online is to install a travel eSIM at home and switch it on when you land at Taoyuan (TPE) or Songshan (TSA). AirOva sells unlimited plans for Taiwan: no data cap, priced by the number of days. The eSIM connects to Taiwan Mobile, with 5G where available; each plan card lists its network.

Which Taiwan plan to choose

Every Taiwan plan is unlimited, so the only choice is the number of days: 1, 3, 5, 7, 10, 15, 20 or 30. Pick a length that covers the whole stay, from landing to departure — for a 12-day trip, the 15-day plan. There are no gigabytes to size: a light week of maps, messaging and transit and a heavier one with photos, social media and video calls run on the same unlimited plan.

Coverage: cities, rail and the east coast

Expect fast 4G and 5G in Taipei, Kaohsiung, Taichung and Tainan, full coverage on the MRT and the High Speed Rail, and good signal along the east coast in Hualien and Taitung. The gaps are high in the mountains: Alishan and the deeper trails of Taroko can drop out, so download offline maps before a hike. Convenience stores and MRT stations also have plentiful Wi-Fi, a handy backup.

Arriving at Taoyuan or Songshan

After landing, turn off airplane mode, switch the eSIM line on, choose it for mobile data and enable Data Roaming for that line; the plan is prepaid, so roaming adds no charge. Keep roaming off on your home SIM, but leave it in the phone for bank codes. You skip the airport SIM counter queue, which helps when your first moves are an EasyCard top-up and a hotel check-in. Validity starts on the first connection in Taiwan, so installing a few days early costs nothing — see how to install an eSIM.

Apps worth setting up before you go

Taiwan has open, unrestricted internet, so no VPN is needed and Google Maps works well — unlike in mainland China. Get an EasyCard for the metro, buses and convenience stores and add EasyWallet to check its balance; Taipei Metro (Taipei MRT Go) and Bus+ handle transit, and Klook or KKday sell High Speed Rail tickets and attraction entry. Night markets are easiest to find by map, since many good stalls have no sign in English. Taiwan's tourist SIMs are good value too, so what an eSIM saves is the airport queue and swapping out your home SIM — our eSIM vs pocket Wi-Fi vs local SIM comparison explains when each wins. The Taiwan eSIM guide covers the full setup.

One more Taiwan tip: if your trip includes Hualien, Taroko or the rest of the east coast between June and October, check typhoon forecasts and keep live weather updates on, because east-coast travel is often suspended even when the network holds up. Everything else is simple: choose enough days to cover the whole stay, install at home, and you'll walk out of Taoyuan or Songshan already online, with Google Maps routing you into Taipei.
