A deep-dive into Airalo's Taiwan eSIM: the Jiyou Mobile package on Chunghwa Telecom, real-world speeds in Taipei, 5-minute setup walkthrough, genuine pros and cons — and when a cheaper alternative beats it.
Airalo is a Singapore-based eSIM marketplace founded in 2019, operating in 200+ countries. For Taiwan, Airalo sells a package called Jiyou Mobile, which runs on Chunghwa Telecom (中華電信) — Taiwan's largest carrier with the best national coverage, particularly strong 5G in Taipei and solid 4G across rural and mountainous regions.
Airalo's main appeal is flexibility: choose your data size from 1 GB to 20 GB, top-up instantly through the app if you run low, and use the same platform for regional multi-country eSIMs. That said, Airalo is not the cheapest option for everyone — for short trips of 3–5 days, there are better-value alternatives.
Airalo was founded in 2019 in Singapore and operates as an eSIM marketplace covering 200+ countries and territories. Travellers buy data eSIMs for individual countries or regional bundles through the Airalo app or website — no physical SIM swap, no queuing at airport kiosks, and installation can be done from home before you travel.
Airalo's model is that of an aggregator: it purchases data capacity from local carriers in each country and resells it as eSIMs to travellers. For Taiwan, Airalo uses a local provider called Jiyou Mobile, which accesses Chunghwa Telecom's infrastructure.
Prices below are approximate USD as of early 2026 — always check real-time pricing at airalo.com before buying as promotions and rates change frequently.
| Data | Validity | Approx. Price | Best for | Notes |
|---|---|---|---|---|
| 1 GB | 7 days | ~$4–5 USD | Short trip, light use | Maps + messaging only — not enough for streaming |
| 3 GB | 30 days | ~$9–11 USD | 7–10 day average use | Comfortable for a week-long trip with normal usage |
| 5 GB | 30 days | ~$13–16 USD | 10–14 days, heavier use | Covers Maps, social media, some streaming |
| 10 GB | 30 days | ~$18–22 USD | 2+ weeks or hotspot | Good if sharing hotspot with a laptop occasionally |
| 20 GB | 30 days | ~$26–32 USD | Long trip / heavy hotspot | Largest available — no unlimited option on Airalo |
⚠️ Airalo does not offer an unlimited plan for Taiwan. If you need truly unlimited data, you'll need to look at alternatives like Holafly (unlimited but more expensive, no hotspot) or Klook unlimited (best value for short trips).
Chunghwa Telecom (中華電信) is Taiwan's state-owned carrier and largest network, with 5G coverage across central Taipei, Taichung, Kaohsiung and Taoyuan Airport. Rural and mountainous areas — including Jiufen, Yangmingshan and Wulai — have reliable 4G LTE coverage, although speeds are lower than in the city centre.
Compared with Taiwan Mobile and Far EasTone, Chunghwa generally outperforms both in remote areas and mountain zones. Running on Chunghwa is a genuine advantage for Airalo's Taiwan eSIM, especially for travellers heading to day-trip destinations outside Taipei.
ℹ️ Speed figures are approximate real-world observations, not guaranteed specs. Actual speeds vary with device hardware, location and network congestion.
Do steps 1–3 at home before you fly. Activate when you land at Taoyuan Airport.
Get the Airalo app from the App Store (iOS) or Google Play (Android). Sign up with an email address — takes under 2 minutes.
Type Taiwan in the search bar, select the Jiyou Mobile package that matches your trip length and expected usage, then pay by card or PayPal.
Go to My eSIMs → tap Install → scan the QR code in your phone's Settings, or tap "Install Directly" if your device supports it. The eSIM profile downloads in seconds. Do this at home on Wi-Fi — you won't need a connection at the airport.
In Settings → Cellular / Mobile Data, select the Jiyou Mobile line for data. Enable Data Roaming on that line. Your home SIM stays in the phone for calls and SMS (bank OTPs still work).
Toggle Airplane Mode on and off after landing — your phone connects to Chunghwa Telecom automatically. Data validity typically starts from first use, not purchase date. Check the specific activation terms for your package.
From hands-on testing across Taipei and popular day-trip destinations, Airalo on Chunghwa delivers a reliable experience for everyday sightseeing. Here's what to expect:
In out-of-city areas such as Jiufen and Yangmingshan, 4G is accessible but slower than in Taipei. At Wulai (deep in the mountains) there are occasional weak-signal spots — normal for any carrier in dense forest terrain.
The value improves significantly on longer trips, especially if you're visiting multiple Taiwanese cities (Taipei, Kaohsiung, Taichung) and using data heavily throughout.
Buy the Airalo Asialink regional eSIM covering Taiwan, Hong Kong, Japan, Korea and more in one package — no need to buy separate country eSIMs for each stop.
Need hotspot for video calls and laptop work? Airalo supports tethering and lets you top-up if your package runs low — flexibility that fixed unlimited plans don't always offer.
Install the eSIM at home and you're connected the moment you walk off the plane at Taoyuan. No airport kiosk, no plastic SIM, no wasted time.
For a short trip where you just need simple reliable data, Klook unlimited (approx. 3 days starting ~THB 199) undercuts Airalo on price and removes the need to track GB usage.
No unlimited option on Airalo. If you plan to stream Netflix, YouTube or use heavy hotspot throughout a long trip, 20 GB may not be enough. Consider Holafly (pricier, no hotspot) for unlimited data.
If you need to call restaurants, tour operators or local services with a Taiwanese number, a data-only eSIM won't cover you. Buy a physical SIM with voice service instead.
eSIM requires eSIM-capable hardware and an unlocked device. Check compatibility at airalo.com/compatible-devices — and unlock your phone before travelling if needed.
