Taiwan eSIM on Airalo: fixed data or unlimited, plus ICHINEW or ICHI
Affiliate disclosure: this post uses affiliate links and the codes ICHINEW and ICHI; I may earn a commission at no extra cost to you. Package details and the final Airalo checkout total decide what you receive and pay.
Choose an eSIM for Taiwan based on the actual trip: local network coverage, data amount, validity, hotspot needs, activation method, support and final price. Airalo is one option, not the automatic winner. Compare it with the relevant local SIM/eSIM and other travel-eSIM choices before paying.
Decision rule: For Taiwan, pick the connectivity option that fits the local network and your real data needs first. If Airalo wins, handle ICHINEW or ICHI on the dedicated promo-code page. Airalo promo-code guide

Fast answer

- Unlimited does have a limit Current unlimited packages reduce speed to 1 Mbps after 3 GB of usage in a day.

Current Airalo Taiwan fixed-data plans and prices
The Xie Xie fixed-data menu below was rechecked on July 20, 2026. Airalo can change prices, package names, networks, or available plan types, so use this as a dated comparison and verify the live store before buying.
| Data | Validity | Price checked | Practical fit |
|---|---|---|---|
| 1 GB | 7 days | US$4 | Very light use with frequent hotel or café Wi-Fi |
| 2 GB | 15 days | US$7 | Messaging, occasional maps, and limited browsing |
| 3 GB | 30 days | US$9 | Light one-week trip or careful longer stay |
| 5 GB | 30 days | US$12 | Balanced choice for a normal one to two week trip |
| 10 GB | 30 days | US$19 | Regular uploads, heavier browsing, or limited tethering |
| 20 GB | 30 days | US$29 | Heavy phone use, frequent uploads, or a longer stay |
Do not choose by price alone. A plan that expires before the final day or runs out before a day trip to Jiufen, Sun Moon Lake, Alishan, or southern Taiwan is not the cheaper plan in practice.
Current Airalo Taiwan unlimited packages
Airalo also lists unlimited Taiwan packages. They are simpler when daily usage is unpredictable, but the word unlimited needs context: the packages checked for this guide reduce speed to 1 Mbps after 3 GB of usage in a day.
| Validity | Price checked | What to consider |
|---|---|---|
| 3 days | US$12.50 | Short stopover or weekend with heavy phone use |
| 5 days | US$19 | Short city break without tracking a fixed allowance |
| 7 days | US$29.50 | One-week trip with frequent uploads or streaming |
| 10 days | US$35 | Longer trip with variable daily usage |
| 15 days | US$49 | Two-week itinerary where convenience matters more than lowest cost |
| 30 days | US$69 | Long stay, but compare the fair-use policy and local prepaid options |
A fixed 5 GB plan costs much less than a seven-day unlimited package, so unlimited is not automatically the value choice. It makes more sense when you expect heavy daily use and accept the reduced-speed threshold. For remote work, long video calls, or tethering a laptop, confirm whether 1 Mbps after the daily threshold is workable before paying.
Which Taiwan eSIM plan fits your trip?
Taipei city break
For three to five days using maps, MRT routes, LINE or WhatsApp, translation, restaurant searches, and tickets, 2 to 3 GB can work. Choose 5 GB when you upload photos and videos throughout the day.
One-week Taiwan loop
For Taipei, Taichung, Tainan, and Kaohsiung with railway planning and regular browsing, 5 GB is the balanced starting point. Ten gigabytes adds room for more uploads and less Wi-Fi dependence.
Mountains and rural routes
More data does not create coverage where the underlying network is weak. Save offline maps, tickets, hotel addresses, and key Chinese place names before trips to mountainous or less populated areas.
Heavy creator or remote-work use
Compare 10 or 20 GB against an unlimited package. The unlimited route reduces speed after 3 GB in a day, which can matter more than the headline allowance.
Airalo Taiwan eSIM or a local tourist SIM or eSIM?
| Option | Best when | Main trade-off |
|---|---|---|
| Airalo fixed-data eSIM | You want to buy and install before departure, need data only, and know roughly how much you use | Fixed allowance and no Taiwanese phone number |
| Airalo unlimited eSIM | You want simple day-based validity and do not want to monitor a fixed total | Speed falls to 1 Mbps after 3 GB in a day |
| Local Taiwan tourist SIM or eSIM | You want a local number, traditional calls, or a local unlimited package | May require on-arrival or in-store purchase, identification, and a different setup flow |
| Home-carrier roaming | Your carrier offers a competitive pass and keeping one line active matters most | Can cost more, and accidental roaming outside the pass remains a risk |
Chunghwa Telecom’s official tourist prepaid range includes 4G and 5G SIM or eSIM day plans with unlimited mobile data and voice credit, available at Taiwan’s major airports and service centers. That local route can be attractive when a Taiwanese number or traditional calling matters. Airalo is usually simpler when you want data prepared before boarding and do not need local voice service.
Taiwan-only or Asia regional coverage?
Buy a Taiwan package when Taiwan is the only destination. Compare an Asia regional plan when the same trip also includes Japan, South Korea, Hong Kong, Macau, Singapore, the Philippines, or another covered market. A regional plan can prevent repeated installation and line switching, but it can cost more or provide a different allowance. Check the complete country list, networks, validity, and final price instead of assuming regional coverage is automatically better.
How to buy a Taiwan eSIM and apply the Airalo codes
- Check the phone first. Confirm that it supports eSIM and is carrier-unlocked.
- Choose fixed or unlimited. Compare the total allowance, validity, daily fair-use rule, and price against your actual itinerary.
- Read Additional Information. Confirm Taiwan Mobile as the listed network, the data-only plan type, activation policy, and any top-up or renewal option shown for that package.
- Open checkout. Select Use Airmoney or code, then choose Code.
- Enter the correct code. New Airalo users should paste ICHINEW. Returning users should paste ICHI.
- Confirm the total changes. Check the final payable amount before completing the order.
Install before departure and connect in Taiwan
- Use stable Wi-Fi. Install through the Airalo app, a QR code, or the manual details while you have a reliable connection.
- Label the line. Use a clear name such as Taiwan eSIM so it is easy to distinguish from your home SIM.
- Check the activation policy. The Taiwan packages checked here begin validity when they connect to a supported network in Taiwan.
- Set the data line after arrival. Turn on the Taiwan eSIM, select it for mobile data, and enable data roaming when the package instructions require it.
- Protect the home line. Disable data roaming and cellular-data switching on your normal SIM unless you deliberately want to use its roaming service.

Taiwan Airalo promo code FAQ
Can I use Airalo promo code ICHINEW or ICHI for a Taiwan eSIM?
Yes. New Airalo users can try ICHINEW, while returning users can try ICHI on an eligible Taiwan eSIM order. Use the code that matches the account type and pay only after the final checkout total drops.
Which Airalo promo code should a new user enter for Taiwan?
A new Airalo user should try ICHINEW. ICHI is for returning users, even though ICHI remains in this page's retained URL.
What should I do if Airalo promo code ICHINEW or ICHI does not work?
Check that the account type matches the code, confirm the spelling, and see whether another promotion is already applied. If the payable amount does not decrease, compare the valid checkout price instead of assuming promotions will stack.
What are the current Airalo Taiwan eSIM prices?
When rechecked on July 20, 2026, fixed-data packages ranged from US$4 for 1 GB over 7 days to US$29 for 20 GB over 30 days. Unlimited packages ranged from US$12.50 for 3 days to US$69 for 30 days. Airalo can change prices and packages, so verify the live store.
Is the Airalo Taiwan unlimited eSIM truly unlimited at full speed?
The unlimited packages checked for this guide reduce speed to 1 Mbps after 3 GB of usage in a day. That can still support light use, but it is a fair-use limit that matters for video uploads, streaming, hotspot use, and remote work.
How much data do I need for one week in Taiwan?
For Google Maps, Taipei MRT and railway planning, messaging, translation, tickets, and light browsing, 3 to 5 GB is a practical starting range. Choose more for frequent video uploads, streaming, tethering, or long days without Wi-Fi.
Should I buy a Taiwan eSIM or an Asia regional eSIM?
Choose a Taiwan plan for a Taiwan-only trip. Compare an Asia regional plan when the same journey includes Japan, South Korea, Hong Kong, Singapore, the Philippines, or another covered destination, because one regional eSIM can be easier than switching plans.
Which network does the Airalo Taiwan eSIM use?
The Taiwan packages checked on July 20, 2026 listed Taiwan Mobile as the primary network. Network details can change by package, so read Additional Information before buying and keep offline maps for mountain or rural travel.
Should I install my Taiwan eSIM before flying?
Yes. Install it over stable Wi-Fi before departure, but read the package's validity policy first. The packages checked for this guide start validity when the eSIM connects to a supported network in Taiwan.
Does the Airalo Taiwan eSIM include a Taiwanese phone number?
The Airalo Taiwan packages checked for this guide are data-only. Use internet-based calling and messaging, or compare a local tourist SIM or eSIM when a Taiwanese number, traditional calls, or an unlimited local package matters.
Final tip
For a normal one-week Taiwan trip, compare the 3 GB and 5 GB fixed plans first. Choose unlimited only when your daily usage justifies the higher price and you understand the 3 GB daily full-speed threshold. Choose a local tourist plan when a Taiwanese number, calls, or local unlimited service matters. Then use ICHINEW if the Airalo account is new or ICHI if it is returning, and trust the final checkout total.
Taiwan fixed-data and unlimited prices, network, plan type, fair-use limit, activation policy, Airalo setup guidance, and local tourist-plan comparison were rechecked on July 20, 2026. The live package page and checkout remain the final reference.
