Mountainous central and eastern regions have significant coverage gaps across all operators. GT (Asia Pacific Telecom) relies on Taiwan Mobile's network for rural coverage outside major cities. No operator operates 3G networks; all 3G services were shut down in June 2024.
The Taiwan mobile network source is linked below as a public network reference. Check the places on your itinerary where the source offers local detail, then confirm the network information for the selected eSIM product. The operator table on this page provides the country-level reference, while the selected product details identify which network information applies to your plan.
Check your accommodation and the places you expect to visit in Taiwan. Indoor reception can differ from an outdoor map, so keep the property Wi-Fi details available as well.
Review the full route rather than checking only the arrival city. Save tickets, addresses and maps offline before longer road or rail journeys.
Check the selected product scope for every country on your itinerary. Your Taiwan plan and a regional plan may have different included destinations and validity periods.
Compare your phone with 4G bands B1, B3, B7, B8, B28, B38 and 5G bands n28, n78 in the existing Taiwan network table. Support for more of the listed bands gives the phone more options when connecting, while the selected product, location and local network conditions determine the service available.
Keep the QR code and installation instructions available offline, and complete each step according to the selected product's instructions.
When validity starts: Validity-start rules can differ by product. Check the selected plan details before installation and travel.
Taiwan is compact enough that you can experience mountains, coast, and city within a single trip. The Central Mountain Range offers forested hiking trails, while Taipei's urban energy provides high-quality museums and street food. Sun Moon Lake and the east coast's Taroko Gorge show strikingly different landscapes. Many travellers compare the island's alpine scenery to Switzerland, but Taiwanese culture, food, and hospitality are unique to Asia. With reliable 4G coverage from Chunghwa Telecom, even remote areas stay connected. Plan to move between regions by high-speed rail or domestic flights-both are efficient and affordable.
These five spots cover Taiwan's natural, modern, and traditional sides. Do not try to visit more than two per day.
Spring (March to May) and autumn (October to November) are the most comfortable seasons. Temperatures range from 18°C to 26°C in lowlands, and humidity is lower than in summer. Cherry blossoms appear in February and March at Wulai and Yangmingshan National Park. Autumn brings clear skies to Taroko and Alishan. Summer (June to September) is hot, humid, and prone to typhoons. If you travel in summer, carry rain gear and check the weather daily. Winter (December to February) is mild in Taipei but cold and rainy in the mountains. For the best balance of pleasant weather and few crowds, plan your trip for late April or late October.
