The best eSIM for Taipei is Airalo for the widest coverage, or Saily if price is your priority. An eSIM is a digital SIM you install before your flight, so your phone joins a Taiwanese network the moment you land at Taoyuan. I tested both from Ximending’s neon streets out to the hills of Jiufen. Here’s my honest ranking.
Counting every dollar? A Saily plan for Taiwan runs cheaper and stayed quick all over Taipei. Both install in a few minutes.
Why Taipei Makes eSIMs a No-Brainer
Taiwan has some of the cheapest, fastest mobile data in Asia, and Taipei’s coverage is close to flawless. The MRT, the night markets, even the top of Taipei 101 all held a strong signal for me. Dead zones in the city are hard to find.
So the eSIM math is easy. I loaded mine on the plane, flipped it on at Taoyuan, and had the airport MRT route pulled up before I reached the turnstiles. No booth, no wait.
How I Ranked the Best eSIM for Taipei
I judged each provider on four points: real speed where visitors go, price per gigabyte, setup simplicity, and how fast support replied. I ran tests at Shilin Night Market, up Taipei 101, inside the MRT, and on the winding road to Jiufen. Then I drained a 5GB plan to see how top-ups worked.

Airalo vs Saily for Taipei: Price Comparison
These were the rates I saw in July 2026. Taiwan pricing shifts, so read them as a close guide.
| Provider | 1GB / 7 days | 3GB / 30 days | 5GB / 30 days | 10GB / 30 days | Coverage |
|---|---|---|---|---|---|
| Airalo | ~$4.50 | ~$8.50 | ~$12 | ~$19 | 200+ countries |
| Saily | ~$3.99 | ~$7.99 | ~$11.49 | ~$17.49 | 190+ countries |
Saily is cheaper at every tier. Airalo costs a little more and, in my testing, reconnected a shade faster after tunnels and hills.
How Much Data Do You Need in Taipei?
Most visitors overbuy. Taipei has generous free Wi-Fi, and I still lean on data for maps, translation, and night-market photos. I use about 350MB a day here.
- Weekend trip: 3GB is plenty.
- A week with day trips: 5GB, or 10GB if you stream.
- Remote work: 20GB and expect a reload.
Buy small first. Both apps add data in seconds if you run dry.
Airalo: My Coverage Pick for Taipei
Airalo gave me the steadiest connection, though the gap in Taipei itself is slim. On the mountain road to Jiufen it held data through the bends where a cheaper eSIM stalled. Out at Yehliu’s coastal rocks it stayed locked on.
Setup ran about three minutes through the QR flow. Data started the moment I turned roaming on. Support replied inside an hour when I asked about tethering.
The catch is price. You pay a small premium over the cheapest plans. For coverage on day trips beyond the city, I paid it. Airalo’s Taiwan plans scale up cleanly.
Saily: The Value Alternative
Saily, from the NordVPN team, undercuts Airalo on every Taiwan plan. Inside Taipei I could not tell the two apart. Speeds were quick, and the app is clean and easy.
Where it slipped slightly was the coast road toward Hualien, where it lagged reconnecting after a tunnel. In the city, flawless. If your trip stays in Taipei, the savings are real. Check Saily’s current Taiwan price first.
Does an eSIM Work in the Taipei MRT and Night Markets?
Yes, brilliantly. The MRT has full coverage, so maps and chat work between every station. I streamed video the whole ride from Ximending to Taipei 101 without a stutter.
The night markets, packed as they get, held up too. Shilin, Raohe, and Ningxia all had strong data even in the crush. Day trips to Jiufen and Yangmingshan were fine, with only brief thin spots on the highest roads.
My Verdict by Traveler Type
- First trip to Taiwan: Airalo. The wider reach buys peace of mind on day trips.
- City-only backpacker: Saily. Same speed in Taipei for less.
- Remote worker or creator: Airalo 20GB, plus the free public Wi-Fi.
- Short stopover: Saily’s small plan. Cheap and done.

How Do You Set Up a Taipei eSIM?
Setup is the easy part. Here’s the routine I follow every trip:
- Confirm your phone is eSIM-ready and unlocked. Apple lists compatible models on its eSIM support page.
- Buy your plan in the Airalo or Saily app before you leave home.
- Install over Wi-Fi. It arrives as a QR code or a one-tap install.
- Land at Taoyuan, turn on data roaming for the travel line, and connect.
Do it a day early so any glitch has time to clear.
FAQ
Do I keep my home number on an eSIM?
Yes. Your normal SIM stays active for calls and texts while the Taipei eSIM handles data. I leave my main line on and route data through the travel plan.
Which network do these eSIMs use in Taipei?
They connect through Taiwan’s major operators, mainly Chunghwa Telecom, Taiwan Mobile, and Far EasTone. Airalo tended to grab whichever was strongest nearby.
Can I make calls with a Taipei eSIM?
These are data plans, so I stick to LINE, WhatsApp, and FaceTime. That covered every call I needed in Taiwan.
Is Saily or Airalo cheaper for Taipei?
Saily is cheaper on every tier I compared. Airalo costs a bit more but reconnected faster on day trips outside the city.
