Tips for Travelers in Taiwan
Make the most of your Taiwan trip with these connectivity tips from fellow travelers:
Download and install your AloOui Taiwan eSIM profile at home before departure. It won't activate until you land — so you're ready the moment you step off the plane at Taoyuan International Airport.
Your AloOui eSIM runs alongside your existing SIM. Keep your home number for calls and WhatsApp while using the Taiwan eSIM for data — no need to choose.
Before heading to Taroko Gorge, the Alishan mountain trails, or the Penghu Islands, download offline maps on Google Maps or Maps.me. Even with unlimited data, offline maps save battery and load instantly in areas with weaker signal.
On the Unlimited Lite plan, enable Low Data Mode on your phone to stretch your 1GB daily full-speed quota further — great for MRT rides and sightseeing days with light usage.
Taiwan's top experiences — Taroko Gorge tours, Alishan sunrise trains, Sun Moon Lake boat rides, Jiufen lantern festivals, and night market food tours — fill up fast in peak season. Use your AloOui data to book online the moment you arrive, or even on the plane.
Taiwan's HSR, TRA trains, and buses have limited or no onboard Wi-Fi. Use your AloOui eSIM for reliable connectivity between Taipei, Taichung, Tainan, Kaohsiung, and the east coast throughout your journey.
For Business Travelers & Digital Nomads
Taiwan is one of Asia's most connected tech hubs — from the semiconductor corridors of Hsinchu Science Park to the startup scene of Taipei's Xinyi District and the creative co-working spaces of Da'an. Here's why AloOui's Unlimited Plus is the go-to plan for professionals.
The Plus plan gives you network priority — so even in crowded business districts, airports, or busy Taipei CBD, your connection stays fast and stable.
Video calls, large file uploads, cloud syncing — 2GB of full-speed data per day keeps your workflow uninterrupted, with 2 Mbps fallback for lighter tasks.
Share your connection with your laptop or tablet. Perfect for working from a café in Da'an, a hotel in Xinyi, or a co-working space in Zhongzheng without relying on public Wi-Fi.
Extended stays covered. Whether you're on a month-long project in Taiwan or travelling across the region, one plan keeps you connected the whole time.
Scan a QR code and you're online. No SIM procurement, no corporate roaming plans, no waiting at a carrier store. Instant activation means you're productive from day one.
One flat rate, no surprise roaming bills. Ideal for expense reporting and budget-conscious professionals who need reliable data without unpredictable carrier charges.
