These are our 6 picks. See every Taiwan plan from every provider, sorted by price per GB.All Taiwan plans →What we found in Taiwan
Taiwan Mobile sells its tourist SIM at Taoyuan Airport only to visitors who show a passport and a second original ID, such as a visa or a Taiwan driver's license. A travel eSIM is bought online, with no airport counter involved.
We compared 6 travel eSIMs for Taiwan on the list price of a 10 GB plan that lasts 30 days. Yesim has the lowest price in this comparison at $13.30, and Yesim has the lowest price per gigabyte at $0.74/GB. If two 10 GB prices ever match, the provider that names its Taiwan network ranks first.
Taiwan has had three mobile operators since the 2023 mergers: Chunghwa Telecom, Taiwan Mobile and Far EasTone (FET). Chunghwa held the largest share of subscribers, 39.1%, in the National Communications Commission's first-quarter 2025 figures, and Speedtest puts the national median mobile download at 110.77 Mbps for September 2026. Nomad and Sim Local run on Chunghwa and Taiwan Mobile, Ubigi on FET and Taiwan Mobile, and Airalo on Taiwan Mobile alone. Yesim and GigSky do not publish their Taiwan network.
If you know how long you are staying but not how much data you will use, Plan Match suggests a size in three questions. Every Taiwan plan, sorted by price per GB, is on our Taiwan plans page.
The 6 Taiwan eSIMs reviewed
Each review opens with the verdict. Specs, strengths and limitations follow.
Yesim
Our verdictYesim has the lowest 10 GB, 30-day price in this comparison and also leads at 1, 3, 5, 20 and 30 GB. Pass on it if you want to know your Taiwan network before you pay, because Yesim does not publish one.
- Network
- Not published by Yesim
- Hotspot
- Depends on the operator, per Yesim
- Unlimited, 30 days
- Sold; limit not published by Yesim
- Coverage
- Ten main-island cities listed
- Lowest price at most plan sizes
- Only 1 GB plan that lasts 30 days
- No Taiwan network named
- Hotspot not guaranteed
Yesim sells Taiwan plans from 1 GB to 30 GB for 30 days, plus unlimited plans, and it has the lowest list price at every 30-day size it sells. Its 30 GB plan gives the lowest price per GB here. Nomad's 5 GB plan is within a few cents of Yesim's, so compare both if 5 GB is your size.
Yesim does not say which Taiwan network it uses. It says hotspot use depends on the operator and that speed may be limited under the operator's fair-use policy, but it gives no figure, which makes the unlimited plan hard to judge for heavy use. Its coverage list runs from Keelung and Taipei down to Kaohsiung and Pingtung. TRAVELCITY takes 15% off.
Ubigi
Our verdictUbigi is second on the 10 GB, 30-day price and is the lowest-priced plan here that names its networks, FET and Taiwan Mobile. Pass on it if you want 5 GB, because Ubigi does not sell that size in Taiwan.
- Network
- FET and Taiwan Mobile
- Hotspot
- Data sharing allowed
- Unlimited, 30 days
- 60 GB at full speed, then 2 Mbps
- Small plans
- 1 GB and 3 GB last 7 days
- Two named networks
- Only 25 GB plan in this comparison
- Published limit on unlimited
- No 5 GB plan
Ubigi lists FET and Taiwan Mobile on its 10 GB and 25 GB Taiwan plans and allows data sharing with other devices. The 25 GB plan is the only one at that size here and costs less per GB than Ubigi's 10 GB plan, so it is the step up if 10 GB looks tight.
The 30-day unlimited plan gives 60 GB at full speed over the whole plan, then slows to 2 Mbps until it ends. That is a running total, not a daily allowance. The 15-day and 7-day unlimited plans slow down after 30 GB and 20 GB. TRAVELCITY10 takes 10% off.
3Lowest 50 GB, 30-day priceNomad$16ATESIM · 20%
Our verdictNomad has the lowest 50 GB, 30-day price in this comparison and runs on Chunghwa and Taiwan Mobile. Pass on it for unlimited data beyond 10 days, because its Taiwan unlimited plans stop there.
- Network
- Chunghwa and Taiwan Mobile
- Hotspot
- Allowed
- Unlimited
- 3, 5, 7 or 10 days
- Coverage
- Taipei to Kaohsiung, per Nomad
- Lowest 50 GB price
- Switch between two networks
- Third on 10 GB price
- Code excludes 3 GB and unlimited plans
Nomad names Chunghwa and Taiwan Mobile for Taiwan and lets you switch between them for 4G and 5G if one is weak. It states that its eSIMs support hotspot and tethering. Among 30-day plans, only Yesim's 30 GB plan beats Nomad's 50 GB plan on price per GB.
ATESIM takes 20% off Nomad plans from 5 GB up, but it does not apply to the 3 GB plan or to any unlimited plan. Nomad warns that coverage may not include territories outside the main country.
4Unlimited for up to 30 days, Taiwan MobileAiralo$19
Our verdictAiralo runs on Taiwan Mobile and sells unlimited plans from 3 to 30 days with a published daily limit. Pass on it for a plain 10 GB trip, because three providers here charge less at that size.
- Network
- Taiwan Mobile
- Hotspot
- Allowed if your phone and the network support it, per Airalo's help center
- Unlimited, 30 days
- 3 GB a day at up to 20 Mbps, then 1 Mbps
- Plan type
- 5G, data only
- Daily limit published on unlimited
- Unlimited lengths up to 30 days
- Fourth on 10 GB price
- No discount code
Airalo names Taiwan Mobile as the network for its Taiwan eSIM and sells it as a 5G data-only plan. Its help center says hotspot works as long as your phone and the network support it.
On unlimited plans, Airalo gives up to 20 Mbps for the first 3 GB in each 24-hour cycle, counted from first use, then 1 Mbps. That covers a day of maps and messaging, but a laptop on hotspot will reach the limit quickly. Airalo also sells a 50 GB, 30-day plan, which costs more than Nomad's. No discount code is available.
5Hotspot allowed, Chunghwa and Taiwan MobileSim Local$19.50ATESIM · 10%
Our verdictSim Local names Chunghwa and Taiwan Mobile and allows hotspot and tethering on its 5, 10 and 20 GB plans. Pass on it if price is what matters most, because it is fifth on the 10 GB price.

- Coverage
- Strongest in cities, per Sim Local
- Hotspot allowed in the plan details
- Daily limit published on unlimited
- Fifth on 10 GB price
- No 30-day unlimited plan
Sim Local lists Chunghwa and Taiwan Mobile on its 5, 10 and 20 GB Taiwan plans and marks hotspot and tethering as allowed. It says coverage is strongest in major cities and urban areas and that signal can vary in remote or less populated regions.
Its unlimited plans last 7 or 15 days and include 5 GB a day at full speed, then 1 Mbps until the daily reset. Sim Local also sells Unlimited Pro plans at the same lengths with a different daily limit, so read the details of the one you pick. ATESIM takes 10% off.
6Unlimited hotspot sharing advertisedGigSky$36.49ATESIM · 15%
Our verdictGigSky advertises unlimited hotspot sharing, which helps if you plan to run a laptop from your phone. Pass on it if you want a named network or a low price, because it has the highest 10 GB price here and does not name its Taiwan network.
- Network
- Not published by GigSky
- Hotspot
- Unlimited sharing advertised
- Unlimited
- 7 days
- 30-day sizes
- 5 GB and 10 GB
- Hotspot sharing advertised
- Highest 10 GB price here
- No 50 GB plan
- No Taiwan network named
GigSky's Taiwan page advertises unlimited hotspot sharing but does not name the network it uses in Taiwan. Its 30-day plans come in 5 GB and 10 GB sizes, with smaller plans at shorter lengths and a 7-day unlimited plan. ATESIM takes 15% off.
Once a GigSky plan starts, it cannot be paused, and switching the eSIM off does not stop the countdown.
The bottom line
For a 10 GB, 30-day trip, Yesim has the lowest price in this comparison at $13.30. Yesim also has the lowest 30-day price at 1, 3, 5, 20 and 30 GB and on unlimited, but it does not name its Taiwan network or promise hotspot use.
If you want a named network, Ubigi on FET and Taiwan Mobile is next at 10 GB. For 50 GB, Nomad has the lowest 30-day price, on Chunghwa and Taiwan Mobile. For a laptop, Nomad, Sim Local and Ubigi allow hotspot use in their plan details, and GigSky advertises unlimited sharing. If Taiwan is one stop on a longer trip through Asia, compare Ubigi's Best Asia plan with separate country plans before you buy.
What Taiwan data actually costs
Price per GB drops from $2.77/GB at 1 GB to $0.78/GB at 50 GB. Buying one size up often costs less per GB than topping up later. Full list on the live Taiwan plans table.
A 50 GB plan costs 72% less per GB than a 1 GB plan. Source: All Things eSIM live plan feed, 13 November 2026.
The “unlimited” trap
Unlimited 30-day plans run $43.22 to $69, and 1 of the 3 publish a daily cap before speeds drop. Check the cap before you pay for a label.
How we rank Taiwan eSIMs
We rank by the 30-day 10 GB country-plan price, pulled daily from each provider’s catalog. When two totals match, a host network named on the shop or SKU breaks the tie.
Taiwan eSIM FAQs
Should I buy a tourist SIM at Taoyuan Airport or a travel eSIM?
Taiwan Mobile sells a tourist SIM or eSIM at its Taoyuan Airport counters, with 3, 5 and 7-day unlimited plans and some call credit included. You need your passport and a second original ID, and the counters keep set opening hours, so a late arrival can miss them.
A travel eSIM is bought online and installed before you leave, so data works as soon as you land. Ubigi, Yesim and Airalo describe their Taiwan plans as data only. Choose the airport SIM if you need a Taiwan phone number.
Will my eSIM work on Penghu, Kinmen or Matsu?
None of these providers lists coverage for Penghu, Kinmen or Matsu. If your trip includes the outlying islands, confirm with the provider before you buy. On the main island, Nomad describes coverage from Taipei to Kaohsiung, and Yesim lists ten cities from Keelung in the north to Pingtung in the south.
Can one eSIM cover Taiwan and Japan, Hong Kong or South Korea?
A Taiwan plan works only in Taiwan. Ubigi's Best Asia plan covers Taiwan on FET and Taiwan Mobile, plus Japan, Hong Kong, South Korea and 13 other destinations, but it costs more than Ubigi's Taiwan plan at the same size. Two country plans give you a separate allowance in each place, so compare both totals before you choose. Our Hong Kong guide and Japan guide rank plans for those legs.
Can I use my Taiwan eSIM as a hotspot?
Nomad and Sim Local allow hotspot and tethering, and Ubigi allows data sharing. GigSky advertises unlimited hotspot sharing. Airalo's help center says hotspot works when your phone and the network support it. Yesim says it depends on the operator, which makes it the least certain option here for a laptop.
When should I install the eSIM, and when does the plan start?
Install it at home over Wi-Fi, because installation needs a stable connection. Nomad, Ubigi, Yesim and GigSky start the plan when the eSIM first connects to a network in Taiwan, so installing early costs you no days. Airalo does the same for most plans and lists the rule under each plan's validity policy. Sim Local says some plans start counting at installation, so check the plan details first. Nomad plans activate on their own 60 days after purchase if unused, and Yesim gives you 180 days to start a Taiwan plan.
What does unlimited mean on these Taiwan plans?
Each provider sets its own limit. Ubigi's 30-day plan slows to 2 Mbps after 60 GB in total. Airalo slows to 1 Mbps after 3 GB a day, and Sim Local's standard unlimited plans do the same after 5 GB a day. Yesim refers to a fair-use policy without publishing a figure. Nomad and GigSky sell unlimited plans only for short stays, up to 10 days and 7 days.
What if I run out of data in Taiwan?
Ubigi lets you recharge in its app even without Wi-Fi, and Nomad sells add-on data that attaches to the eSIM you already have. Yesim offers balance top-ups, and Airalo sells top-up packages. If you expect to use more than 10 GB, Yesim's 20 GB and 30 GB plans and Ubigi's 25 GB plan cost less per GB than their 10 GB plans.
