You’ve just landed at Taipei Taoyuan Airport, and you’re debating: “Should I buy a tourist SIM, or can I manage without it?” It’s a fair question—many travellers wonder if Taipei’s Wi‑Fi, hotel networks, or roaming are enough for short trips. Let’s break down what’s actually possible and what might leave you disconnected in the middle of your journey.
I. Why Travellers Ask This Question
Not every traveller wants to line up at the airport to buy a SIM card.
You might be arriving late at night, staying only a few days, or already have Wi‑Fi at your hotel.
So, you wonder:
- Can I rely on Taipei’s public Wi‑Fi?
- Will my global roaming work smoothly?
- Are there alternative ways to get data without a local SIM?
Let’s explore each realistically.
II. Using Free Wi‑Fi in Taipei: Convenient but Limited
Taipei is actually one of Asia’s cities with the best free Wi‑Fi programs, such as TPE‑Free and iTaiwan.
Where you can connect easily
- At Taoyuan and Songshan airports
- In most metro stations and tourist spots
- Many cafés and convenience stores (e.g., Starbucks, 7‑Eleven)
However:
- You need to register using a passport (may require verification SMS).
- Signals can drop outside city centers.
- Streaming, maps, or ride‑hailing apps can lag or disconnect.
Good for: Email, messaging, checking schedules. Not reliable for: Navigation, translation, social media uploads, or travel apps.
III. Relying on International Roaming
If you already have roaming activated, it can connect automatically to networks like Chunghwa Telecom or Taiwan Mobile.
Pros:
- No SIM swap is needed.
- Keep your home number active for OTPs or calls.
Cons:
- Daily roaming fees can reach USD 10–15/day.
- Speed may be throttled or unstable.
- Some carriers don’t include Taiwan in their coverage zone.
For travellers staying more than 2–3 days, roaming quickly becomes more expensive than local data options.
IV. Portable Wi‑Fi Devices: Great for Groups, Not for Light Travelers
Some visitors rent Wi‑Fi pocket routers at the airport or online. These let you share one data connection among several devices.
Advantages:
- Works with all phones, laptops, and tablets.
- No need to deal with telecom apps or setup.
Drawbacks:
- Must return it before leaving.
- The battery lasts only 6–8 hours.
- Bulky for solo or short trips.
This can make sense for families or small teams, but not for solo travelers exploring Taipei freely.
V. eSIM: The Convenient Alternative for Modern Travellers
If you don’t want to queue, carry devices, or pay roaming fees, the most practical option is to use an eSIM plan for Taiwan.
An eSIM is a digital SIM that you install by scanning a QR code on your phone. Within minutes, you can get local‑rate data on Taiwan networks like Chunghwa or Taiwan Mobile, without any physical SIM card.
Benefits:
- Works instantly after landing.
- Uses local 4G/5G speeds.
- No need to pick up or return anything.
- Keep your home SIM active for calls.
You can activate one directly from taiwanesim.com, which offers prepaid plans starting from just a few days up to a month — perfect for city trips or remote work stays.

VII. Can You Visit Taipei Without a Tourist SIM Card
Technically, yes — you can get by using Wi‑Fi and roaming. But in reality, you’ll face:
- Gaps between hotspots;
- Apps not loading when you need them most;
- Taxi/hotel communication issues.
For most travellers, installing an eSIM before landing ensures you have:
- Constant access to maps, Line, Uber, and translation apps;
- No waiting in airport lines;
- A smooth, connected travel experience from the moment you arrive.
VIII. Quick Setup Checklist Before Flying to Taipei

- Install your eSIM QR code with Wi‑Fi before departure.
- Keep your home SIM active (for SMS, OTP, or calls).
- Enable data roaming for your eSIM in Settings.
You’re ready to land and stay connected instantly.
IX. FAQs
Can I survive in Taipei with just free Wi‑Fi? Yes, but expect patchy connections and password access in cafés. It’s not ideal for navigation or live translation.
Do I need a local number to use apps like Uber or LINE? No. Most apps work perfectly with a foreign number once connected to mobile data.
Can I use Wi‑Fi and eSIM at the same time? Yes. eSIM simply ensures coverage when you’re between Wi‑Fi zones.
