Quick Answer

The best-value eSIM for Taiwan is eSIM4, starting at $2.98 for 1GB. That is the cheapest 1GB plan of the 8 providers we compared, where entry prices run from eSIM4’s $2.98 up to $4.99 with GigSky.

eSIM4 also wins the 2GB plan at $5.98 and the cheapest 3-day unlimited plan at $10.98. On the mid tiers Nomad and Jetpac tie 3GB and 5GB at $7.00 and $10.00, aloSIM undercuts on 10GB at $12.50, and Nomad takes 20GB at $25.00. We show every one of those rival wins honestly in the tables below.

Prices were verified July 2026.

The cheapest Taiwan eSIM depends entirely on how much data you actually need, so a single headline number tends to mislead. We priced every major provider plan by plan, from a weekend in Taipei to a two-week loop around the island.

eSIM4 comes out cheapest on the small fixed plans and the short unlimited burst, while Nomad, Jetpac and aloSIM shade a mid or large tier here and there.

Plan size calculator

Tell us your trip length and how you use your phone, and we’ll point you to the smallest eSIM4 plan that won’t run out, so you pay the least. As a rough guide, short trips need 1GB to 3GB, a full week runs 5GB to 10GB, and heavy use or long stays are best on unlimited.

How do you use your phone?

This is a rough guide for typical use with offline maps and some free wifi. If you stream in HD or tether a laptop all day, lean toward unlimited.

What is a Taiwan eSIM?

An eSIM is a digital SIM built into your phone that carries mobile data, so there is no plastic card to slot in. You buy the plan online, scan a QR code to install it, and it connects to a Taiwan network the moment you land at Taoyuan International.

Your home SIM stays exactly where it is, so you keep your usual number.

These are travel data eSIMs, made for staying online without roaming bills or an airport SIM queue. From the moment you clear arrivals you can pull up maps, run a translation app for a night-market menu, and message home, all on a local connection.

Taiwan price comparison: fixed data

eSIM4 has the cheapest fixed plan at the two smallest sizes, 1GB and 2GB, so those rows are green under eSIM4. From 3GB up the picture shifts and we show it plainly. Nomad and Jetpac tie for cheapest at 3GB and 5GB, aloSIM wins 10GB, and Nomad wins 20GB, so each of those rows is green under the true winner, not eSIM4.

Airalo, Nomad and Jetpac sell larger 30GB to 50GB fixed plans that sit outside this grid, while eSIM4’s fixed range tops out at 20GB and then moves to unlimited by duration. Prices were checked July 2026 against each provider’s own Taiwan page and are re-checked monthly.

Value check: price per GB

A low sticker price can mislead on a cheapest search, because a tiny plan often costs the most per GB. Here is what you actually pay per GB, eSIM4 against the cheapest rival that sells a travel-ready plan at each size.

Dollar-per-GB is rounded to the nearest cent. eSIM4 leads on $/GB at the small 1GB and 2GB plans that most short trips buy, then stays within a dollar or so per GB of the cheapest rival on the larger sizes.

Taiwan price comparison: unlimited data

eSIM4 is the cheapest unlimited plan at 3 days, at $10.98, and it is the only provider offering a 15-day unlimited plan here. Nomad edges the middle durations, undercutting on 5, 7 and 10 days, while GigSky owns the very short 1-day and the longer 14, 21 and 30-day options.

Is Roamless’s $3.95 plan actually cheaper?

Roamless lists a 1GB plan at $3.95, which is close to eSIM4’s $2.98, and its 2GB sits at $6.95. On the sizes most short trips buy, eSIM4 is still the cheaper of the two, by 97 cents at 1GB and 97 cents at 2GB, so the teaser isn’t the bargain the first glance suggests.

Where eSIM4 genuinely wins is the small fixed plans and the short unlimited burst. It has the cheapest 1GB and 2GB in this comparison, and the cheapest 3-day unlimited plan at $10.98, which is handy for a long weekend where you don’t want to watch a data counter.

We’re not going to pretend eSIM4 wins everything. Nomad and Jetpac are cheaper at 3GB and 5GB, aloSIM is the value pick at 10GB, and Nomad takes 20GB.

Pick eSIM4 for the small plans and short unlimited trips, and check the tables above for the exact size you have in mind.

Which Taiwan eSIM is right for your trip?

The default value pick is eSIM4, cheapest at 1GB from $2.98, cheapest at 2GB from $5.98, and cheapest on 3-day unlimited from $10.98. The exceptions are worth knowing: Nomad and Jetpac win 3GB and 5GB, aloSIM wins 10GB, and Nomad wins 20GB, so your best pick shifts with how much data you buy.

Short trip or light data

For a couple of days of maps and messaging around Taipei, eSIM4’s 1GB plan at $2.98 is the cheapest way in. Step up to the 2GB plan at $5.98 if you’ll be checking transit routes and posting photos, and it’s still the cheapest 2GB of the eight.

A typical week

A week of daily navigation and social usually lands in the 5GB to 10GB band. eSIM4’s 5GB is $10.98 and 10GB is $17.98, though Nomad and Jetpac undercut at 5GB with $10.00, and aloSIM is the cheapest 10GB at $12.50 if you want the lowest sticker price for a data-heavy week.

Heavy data or a longer stay

For streaming, tethering or a stay of two weeks or more, unlimited saves you watching a counter. eSIM4 is cheapest on the 3-day plan at $10.98 and the only 15-day option at $47.98, while Nomad edges the 5, 7 and 10-day durations if your trip fits one of those.

Families and groups

Buy one plan per phone, and pick unlimited or a larger fixed plan for whoever hotspots the group around a rented apartment or a day trip. eSIM4 plans support tethering, so the person sharing to the others is the one who wants the bigger allowance.

Strict single-plan budget

If you want the rock-bottom price on one specific size, Roamless is a whisker behind eSIM4 at 1GB and Nomad wins the mid tiers, so those are the names to watch when a single plan is all you need. On the small plans and the 3-day unlimited burst, eSIM4 is the better value.

eSIM4: cheapest small plans and short unlimited

eSIM4 eSIM banner
Rating:4.8
Networks:A major Taiwan network on 4G LTE and 5G
Starting price:$2.98 (1GB)
Plan range:1GB to 20GB, plus unlimited from 3 to 30 days
Calls & texts:Available via the Yabb app (paid add-on)
Customer support:24/7 support

eSIM4 is built for the plans most travellers actually buy on a Taiwan trip: a small fixed plan for a city break, or a short unlimited plan for a busy few days. It wins the cheapest 1GB and 2GB in this comparison and the cheapest 3-day unlimited, which covers a long weekend without any topping up.

Pricing. The 1GB plan is $2.98 and 2GB is $5.98, both the lowest here. Every plan runs on a Was/Now sale, so the 1GB drops from $8.10 and the 3-day unlimited falls from $22.50 to $10.98. On the mid tiers eSIM4 stays close rather than cheapest, with Nomad and Jetpac ahead at 3GB and 5GB.

Networks. eSIM4 connects to a major Taiwan network on 4G LTE and 5G, so your data stays local and apps behave the way they should from Taipei to Hualien.

Customer support. Support is available 24/7, so a hiccup on arrival day gets sorted whatever the hour back home.

Pros

  • Cheapest small plans. Lowest 1GB at $2.98 and 2GB at $5.98 of the eight providers.
  • Cheapest short unlimited. The 3-day unlimited at $10.98 beats every rival on that burst.
  • Big Was/Now savings. Every plan runs on a sale, saving up to $59.52 on the 30-day unlimited.
  • 24/7 support. Help is on hand whatever time it is when you land.
  • Easy QR setup. Install before you fly and switch on at Taoyuan in a couple of minutes.

Cons

  • Data only. No Taiwan phone number of its own; voice and texts need the paid Yabb add-on.
  • Not cheapest mid-range. Nomad and Jetpac undercut at 3GB and 5GB, and aloSIM at 10GB.
  • Fixed tops out at 20GB. Above that you move to unlimited by duration rather than a bigger fixed plan.

Saily: simple lineup with a low entry plan

Saily eSIM banner
Rating:4.2
Networks:Local Taiwan partner networks
Starting price:$3.99 (1GB)
Plan range:1GB to 20GB, plus an unlimited plan
Customer support:App chat and email

Saily, from the team behind NordVPN, keeps its Taiwan menu short and clean, which suits travellers who don’t want to scan a long list. Its entry plan sits just above eSIM4 and its unlimited is a single selectable option rather than a duration ladder.

Pricing. The 1GB plan is $3.99, a dollar more than eSIM4, and its 5GB is $11.99 against eSIM4’s $10.98. Its 10GB at $19.99 is pricier than eSIM4’s $17.98 too, so Saily rarely takes a row outright, though its unlimited option at $48.99 with checkout-selectable days can suit a flexible trip.

Networks. Saily connects through local Taiwan partner networks, so coverage in the cities and along the main rail lines is solid.

Customer support. Support runs through in-app chat and email.

Pros

  • Clean, short menu. A handful of clear plans instead of a long tier list.
  • Flexible unlimited. One unlimited plan with the duration chosen at checkout.
  • Trusted brand. Backed by the NordVPN team with a polished app.

Cons

  • Never the cheapest row. Priced above eSIM4 at 1GB, 5GB and 10GB in Taiwan.
  • Thin mid-range. No 2GB plan and a jump from 1GB straight to 3GB.
  • Pricey unlimited. The $48.99 unlimited is dearer than eSIM4’s shorter durations.

Nomad is the rival to watch in Taiwan once you go past the smallest plans. It’s cheapest at 3GB and 5GB, cheapest at 20GB, and it undercuts on the middle unlimited durations, so it’s a genuine value pick for a data-heavy trip.

Pricing. Nomad’s 3GB and 5GB are $7.00 and $10.00, both under eSIM4, and its 20GB is $25.00 against eSIM4’s $27.98. On unlimited it wins 5, 7 and 10 days at $18.00, $24.00 and $33.00. eSIM4 still takes 1GB, 2GB and the 3-day unlimited, so which one wins depends on your size.

Networks. Nomad routes through local Taiwan partner networks with good city and rail coverage.

  • Big fixed plans. Goes up to a 50GB plan for a long, heavy stay.

Cons

  • Loses the small plans. Its 1GB is dearer than eSIM4, and there’s no 2GB tier.
  • No short unlimited edge. eSIM4’s 3-day unlimited undercuts Nomad’s.
  • No number. Data only, with no local Taiwan phone number.

Jetpac packs the widest fixed menu of any rival here, with sizes from 1GB up to 40GB. It matches Nomad on the two mid tiers most travellers buy, so it’s a fair pick if you want a specific in-between size.

Pricing. Jetpac’s 3GB and 5GB are $7.00 and $10.00, tying Nomad for cheapest and undercutting eSIM4. Its 10GB at $14.99 is the second-cheapest at that size, though its 20GB jumps to $35.00, the dearest 20GB in the table. eSIM4 keeps the 1GB, 2GB and 3-day unlimited wins.

  • Good 10GB price. Second-cheapest 10GB at $14.99.

Cons

  • Short entry validity. The 1GB plan lasts just 4 days and the 3GB only 7.
  • Pricey 20GB. At $35.00 it’s the dearest 20GB in the comparison.
  • One unlimited option. Only a 10-day unlimited, and eSIM4 wins the shorter burst.

GigSky leans hard into unlimited, with seven durations from a single day to a full month. It’s the pick if your trip length matches one of its longer unlimited windows that eSIM4 and Nomad don’t cover.

Pricing. GigSky’s fixed plans are the priciest here, with 5GB at $18.69 and 10GB at $31.02, well above eSIM4. Its strength is the unlimited ladder: it owns the 1-day at $4.24, the 14-day at $37.39, the 21-day at $49.29 and the 30-day at $63.74. eSIM4 still beats it on the 3-day at $10.98.

aloSIM is a fixed-only provider whose Taiwan table has one clear headline: its 10GB plan. That single price makes it the value pick for a data-heavy week, even though it’s pricier at the smaller sizes.

Pricing. aloSIM’s 10GB is $12.50, comfortably the cheapest at that size and well under eSIM4’s $17.98. Elsewhere it’s dearer, with 1GB at $4.50 and 20GB at $30.00. It’s the honest winner at 10GB, while eSIM4 keeps the small plans and the short unlimited.

  • Simple fixed range. Six clear sizes with no unlimited to weigh up.

Airalo is the biggest name in travel eSIMs, and its Taiwan menu is the deepest of the lot, with the same data sizes offered across 3, 7, 15 and 30-day validities. That flexibility is its selling point rather than any single low price.

Pricing. Airalo’s 1GB is $4.00 and its 30-day 5GB is $12.00, both above eSIM4. It doesn’t win a row in this comparison, but the ability to pick a shorter validity for a cheaper price, like 5GB for 7 days at $11.00, is useful for a tightly timed trip.

Roamless runs a tidy flat-rate table where every plan lasts a full 30 days, which is generous for the small sizes. Its 1GB is the closest any rival gets to eSIM4, so it’s the one to weigh if you want a low single-plan price with long validity.

Pricing. Roamless’s 1GB is $3.95, 97 cents above eSIM4, and its 2GB is $6.95 against eSIM4’s $5.98. Its larger plans track close to the cheapest, with 5GB at $10.95 and 20GB at $27.45, but it doesn’t win a row here. The 30-day validity on every size is the real draw.

  • Close on small plans. Its $3.95 1GB is the nearest rival to eSIM4.
  • Simple flat rates. Six clear sizes with no fine print.

Cons

  • Still beaten at 1GB and 2GB. eSIM4 undercuts it on both small plans.
  • No unlimited. Fixed only, so no cap-free option for streaming.
  • No number. Data only, with no local Taiwan phone number.

How much data do you need in Taiwan?

Rough bands: light use is 1GB to 3GB, a week runs 5GB to 10GB, and heavy or long trips are best on unlimited. Taiwan leans on data because you’ll live in Google Maps and the Taipei Metro app, lean on Google Translate for menus and signage, and many travellers use LINE for messaging and even splitting a bill, all of which nibble at your allowance through the day.

Light use: 1GB to 3GB

Maps, messaging and light browsing for a weekend or a few days in Taipei fit inside 1GB to 3GB. If you download offline maps and hop on cafe wifi, even 1GB stretches further than you’d expect.

A typical week: 5GB to 10GB

Daily navigation, social scrolling, the odd video call and some streaming push a week into the 5GB to 10GB band. This is the most common one-week choice, and it covers a loop taking in Taipei, Taichung and Kaohsiung without much thought.

Heavy use or long stays: unlimited

Streaming on the high-speed rail, tethering a laptop from a cafe, or a stay of two weeks or more all point to unlimited. eSIM4 is cheapest on the 3-day burst and the only 15-day option, so it’s a strong pick for short heavy trips and mid-length stays.

Taiwan’s mobile networks and coverage

Taiwan runs on three main carriers: Chunghwa Telecom, Taiwan Mobile and FarEasTone. Chunghwa is the largest and has the broadest reach, Taiwan Mobile and FarEasTone are close behind in the cities, and travel eSIMs usually route through one of the three.

Coverage across Taipei, the west-coast cities and the high-speed rail corridor is excellent, with 5G live in the main urban areas and 4G LTE everywhere else.

For the mountainous east and the higher trails around Taroko Gorge, Chunghwa tends to have the widest reach, so a plan riding a strong local network matters if you head off the west coast. eSIM4 connects to a major Taiwan network on 4G LTE and 5G, so you get the same backbone the pricier providers rely on.

One quirk to note: signal can drop in the longer rail tunnels and in remote gorge sections, which is normal rather than a fault with your eSIM.

Why some cheap eSIMs feel slow or block apps

Some budget eSIMs route your data out through a server in another country to cut costs. That adds lag, drags speeds down, and can make banking or streaming apps misbehave because they think you’re somewhere else entirely.

Before you buy, it’s worth checking the eSIM gives a local Taiwan connection so maps, messaging and banking apps load normally. eSIM4 connects to a major Taiwan network, so your data stays local on 4G LTE and 5G rather than looping through a distant server.

Is unlimited data really unlimited?

For normal use, yes. Most unlimited travel eSIMs apply a fair usage policy, running at full speed up to a daily high-speed allowance and then easing the speed for the rest of that day before resetting the next morning.

Everyday maps, messaging, browsing and social won’t get near that ceiling.

If you plan to stream in HD for hours or tether a laptop as your main connection, it’s worth checking the daily allowance before you buy. eSIM4’s unlimited plans are listed by duration in the table above, and the fair-usage terms show at checkout.

eSIM vs airport SIM, pocket wifi and local SIM

A travel eSIM is usually the cheapest, simplest way to get online in Taiwan. You install it before you fly, pay no deposit, and it works the moment you land at Taoyuan.

The alternatives all have trade-offs worth knowing.

  • Airport or physical SIM. Prices are broadly similar, but you queue at an arrivals counter and swap out your home SIM, which means losing your usual number while the local card is in.
  • Pocket wifi. A rented router several people can share, which suits groups, but it means daily rental, a device to carry and charge, and a return before you fly home.
  • Local Taiwan eSIM. Can include a Taiwan phone number, handy for restaurant and hotel bookings, but it usually costs more than a straightforward travel eSIM.

For most travellers a travel eSIM wins on price and convenience. If you do need a local number, eSIM4’s Yabb app add-on gives you one without a separate SIM.

Will your phone work with an eSIM in Taiwan?

You need an eSIM-compatible, carrier-unlocked phone, and most handsets from the last few years qualify, including the iPhone XS and newer, Google Pixel 3 and up, and recent Samsung Galaxy S and Note models. To check, dial *#06# and look for an EID number, or open Settings and see if there’s an Add eSIM option.

Apple’s and Google’s official eSIM guides walk through it if you get stuck.

Phones bought on a carrier contract must be unlocked before you travel, because a locked handset won’t accept a new eSIM. Your home SIM stays in place, so you keep your normal number and apps while the eSIM handles your data in Taiwan.

How to set up your Taiwan eSIM

Install it before you fly and switch it on when you land, and the whole thing takes a few minutes.

  1. Buy the plan online and you’ll get a QR code by email.
  2. Open Settings, go to Cellular or Mobile Data, and tap Add eSIM.
  3. Scan the QR code and follow the prompts to install it.
  4. On arriving in Taiwan, set the eSIM as your data line and turn on data roaming for it.

If your Taiwan eSIM will not connect

Most connection problems clear in a minute or two, so work through these in order.

  1. Get off the plane and into the arrivals hall so you have a real signal to latch onto.
  2. Toggle airplane mode on and off to force a fresh network search.
  3. Confirm the eSIM is set as your data line and that data roaming is switched on for it.
  4. If it hasn’t picked a network, manually select a Taiwan network in your Settings.
  5. In busy areas where 5G is congested, switch your line from 5G to 4G LTE.
  6. On some Android phones, enter the APN your provider supplies if data still won’t flow.

If you travel with one phone, save the QR code as a photo before you leave. On iPhone you can long-press the image to add the eSIM, and on Android you can scan it from your gallery with Google Lens.

How we compared

We took each provider’s cheapest plan at every size and duration and benchmarked it against the market, covering 8 providers in total. All prices are in USD and were collected in July 2026, verified against each provider’s own Taiwan pages.

We excluded eSIMply, because it mirrors eSIM4 and isn’t an independent competitor, and we left out any free-trial tiers. Prices are re-checked on a regular monthly cadence.

FAQ

For the small plans most short trips use, eSIM4 is cheapest, at $2.98 for 1GB and $5.98 for 2GB, and it also has the cheapest 3-day unlimited plan at $10.98. Roamless runs it close at 1GB with $3.95, and on the mid tiers Nomad and Jetpac are cheaper at 3GB and 5GB while aloSIM wins 10GB. The cheapest choice really depends on the size you buy.

For value on the plans most travellers buy, eSIM4 is our pick, thanks to the cheapest small fixed plans and short unlimited, plus 24/7 support and a local Taiwan connection. If you need a specific mid-size, Nomad and Jetpac are worth a look at 3GB and 5GB.

Our full best eSIM for Taiwan guide ranks them on coverage and app quality too.

Yes. A travel eSIM saves you from roaming charges and the airport SIM queue, and it works the moment you land at Taoyuan.

At $2.98 for 1GB it costs little for a few days of maps and messaging, and you keep your home number active on your usual SIM.

Entry 1GB plans start at $2.98 with eSIM4 and run up to $4.99 across the providers we compared. A typical 5GB plan is around $10 to $12, a 10GB plan sits between $12.50 and $20, and short unlimited plans begin at $10.98 for 3 days.

What you pay comes down to how much data and how many days you need.

For a weekend of maps and messaging, 1GB to 3GB is plenty. A full week of daily navigation, social and some streaming usually lands in the 5GB to 10GB band.

If you’ll stream a lot or tether a laptop, an unlimited plan saves you watching a counter.

They can be, as long as the eSIM connects to a real local network rather than routing your data through a distant server. eSIM4 connects to a major Taiwan network on 4G LTE and 5G, so speeds stay solid and apps behave.

It’s worth checking a plan gives a local connection before you rely on it for banking or maps.

If your phone is eSIM-compatible and carrier-unlocked, yes. Most handsets from the last few years qualify, including the iPhone XS and newer, Google Pixel 3 and up, and recent Samsung Galaxy models.

Dial *#06# to check for an EID, or look for an Add eSIM option in Settings.

The eSIM itself carries data, and you can add a number through the paid Yabb app add-on for calls and texts. That’s handy if you want a number for bookings without carrying a separate local SIM.

Your home number also stays active on your usual SIM.

Yes. Modern phones run dual SIM, so your physical home SIM stays active for calls and texts on your usual number while the eSIM handles data in Taiwan.

You just set the eSIM as your data line in Settings.

A travel eSIM is bought online before you go, works on arrival, and focuses on data, usually at a lower price. A local Taiwan eSIM can include a Taiwan phone number for bookings, but it often costs more and can mean sorting it out once you’re there.

For most trips the travel eSIM is the simpler, cheaper option.

Yes. The eSIM adds a data line and leaves your home SIM in place, so you keep your usual number for calls and texts.

Nothing changes about your existing plan while you’re away.

Your data simply stops until you top up or buy another plan, and there are no surprise overage charges. If you’d rather not think about it, an unlimited plan keeps you online for the full duration you choose.

Install the eSIM before you fly, while you still have wifi at home, so the QR code and profile are ready. Then activate it, or set it as your data line and turn on roaming, once you land in Taiwan.

That way you’re online within minutes of arrival.

Not at the sizes most short trips buy. Roamless lists 1GB at $3.95, but eSIM4’s 1GB is $2.98 and its 2GB is $5.98 against Roamless’s $6.95, so eSIM4 is cheaper on both small plans.

Roamless does give a full 30 days of validity, which is its real draw.

Yes. All three main carriers run 5G, and it’s widely available across Taipei, the west-coast cities and the high-speed rail corridor, with 4G LTE filling in everywhere else.

eSIM4 connects to a major Taiwan network on 4G LTE and 5G, so you benefit where 5G is live.

For everyday use, yes. Most unlimited travel eSIMs apply a fair usage policy, running full speed up to a daily high-speed allowance then easing off until the next morning.

Normal maps, messaging and browsing won’t reach it, but heavy HD streamers should check the daily allowance before buying.

Yes, eSIM4 plans support tethering, so you can share your connection with a laptop or a travel companion’s phone. If you’ll hotspot a lot, pick a larger fixed plan or an unlimited one so the shared data doesn’t run out.

The person sharing is the one who wants the bigger allowance.
