Best ESIM For Taiwan [2026 GUIDE]

If you're planning a trip to Taiwan, you're in for a treat – think lanterns in Jiufen, bubble tea on every corner in Taipei, and misty mountain mornings in Alishan.

But here's the thing no one tells you before you go: getting reliable data in Taiwan can be trickier than you'd expect.

I learned that the hard way. Once, I got completely lost trying to find my hotel in Taipei because my SIM card ran out of data mid-navigation. Another time, I missed out on a last-minute train from Hualien to Taipei because I couldn't get online to book it.

And don't even get me started on trying to order street food in Kaohsiung without Google Translate — let's just say I ended up with something I definitely didn't expect.

In Taiwan, staying connected isn't just about convenience — it's how you travel smart.

You'll need data for everything: hopping between MRT lines, translating menus, calling taxis on rainy Taipei nights, or tracking down those hidden cafés in Taichung that locals love.

I used to waste time buying prepaid SIMs at Taoyuan Airport or random 7-Elevens, only to hit a wall because I needed my passport or couldn't top up online. Then I switched to eSIMs, and it changed everything.

Now, I just buy a plan before my flight, scan a QR code, and I'm connected the moment I land — no queues, no forms, no “uhh… sorry, do you speak English?” moments.

In this guide, I'll walk you through the best eSIMs for Taiwan in 2026. I'll break down their pricing, coverage, and who each one's best for.

TL;DR: My Taiwan eSIM Recommendation

Best eSIM for 7 Days in Taiwan: ESIMTAIWAN.com

Best eSIM for 30 Days in Taiwan: Zensim

Overall Best eSIM for Taiwan: ESIMTAIWAN.com

Before we dive into comparisons, let me tell you why ESIMTAIWAN.com has become my go-to whenever I'm travelling around Taiwan.

On one of my early trips, I underestimated how dependent I'd be on mobile data in Taiwan.

Somewhere between the quiet tea fields of Pinglin and the misty trails of Alishan, I realised that “free Wi-Fi everywhere” is a myth. Even in Taipei, public Wi-Fi can be patchy, and once you're outside the city — say, heading to Sun Moon Lake or exploring Taroko Gorge — it's practically non-existent.

That's when I started using ESIMTAIWAN.com, and honestly, it's been a game changer.

Their unlimited data plan runs on Chunghwa Telecom, Taiwan's strongest and most reliable network, which means you'll stay connected even in rural areas where other carriers drop off. It's 4G LTE speed across the country — smooth enough for Google Maps, Instagram uploads, and even tethering your laptop.

Other small details make a big difference too — like free hotspot sharing, top-up options, and transparent pricing. It's prepaid, so there are no hidden fees, no renewals, and no contract nonsense. Just a straightforward connection that works wherever you go in Taiwan.

If you're planning to hop from Taipei to Kaohsiung, or even work remotely in Hualien for a week, ESIMTAIWAN.com is easily the most reliable and hassle-free choice I've found.

In the next section, I'll break down how it stacks up against Truely, ZenSim, and Eskimo, so you can pick the eSIM that best fits your travel style and budget.

Summary Of The Best eSIMs In Taiwan

eSIM	Data Coverage	Coverage Duration	Price Range
Truely	300 GB, 1 GB, 5 GB, 10 GB, 20 GB, Unlimited	Customisable	USD 1.69 – USD 74.93
eSIMTaiwan.com	Daily 2 GB, Fixed 5 GB, Unlimited	1 – 30 days	Customisable
Eskimo	1 GB, 3 GB, 5 GB, 10 GB	2-year validity from the date of purchase	USD 4 – USD 21
Zensim	5 GB, 10 GB, 20 GB, Unlimited	30 days	USD 15 – USD 51

1. The best eSIM for a 7-day trip in Taiwan
2. The best eSIM for a 30-day trip in Taiwan
3. The best unlimited eSIM package for Taiwan
4. Detailed comparison of each eSIM brand for Taiwan

We also answer your biggest questions like “what's the cheapest eSIM for Taiwan” and the most reliable eSIM for Taiwan so you can make the prime choice.

Best eSIM For 7 Days In Taiwan

eSIM	Plan	Price	Data	Price per GB
eSIMTaiwan.com	7 days	USD 7.99	2 GB daily	USD 0.57/ GB
Eskimo	2-year validity	USD 12	5 GB	USD 2.4/ GB
Zensim	30 days	USD 15	5 GB	USD 3/ GB
Truely	7 days	USD 29.88	Unlimited	USD 4.2/ day

If you're visiting Taiwan for just a week and want something simple and affordable, ESIMTAIWAN.com's 7-day plan is a clear winner. The best part? It runs on Chunghwa Telecom, Taiwan's top local network, so you'll get reliable 4G LTE coverage even when you go beyond Taipei. You can also use it as a mobile hotspot.

Just note that like most “unlimited” or high-data plans, very heavy users might experience slower speeds after intense streaming or uploads, but for maps, messages, and videos, it's more than enough.

If you're the kind of traveller who mostly uses data for directions, WhatsApp, and restaurant searches, Eskimo's 5 GB plan for USD 12 might be all you need. That's USD 2.40 per GB, and it comes with 2 years of validity, meaning you can buy it now and use it later. I like that it allows hotspot sharing and doesn't sneak in daily usage limits. The only catch is that once you hit your 5 GB cap, you'll have to top up for more high-speed data.

Zensim's 30-day, 5 GB plan for USD 15 (about USD 3 per GB) is another good choice for slower-paced travellers or digital nomads spending a few weeks in Taiwan.

The data isn't huge, but it stretches over a full month, making it ideal if you plan to rely on hotel or café WiFi most of the time. Think of it as a low-maintenance plan that quietly keeps you connected for essentials like navigation and messaging without rushing to top up every few days.

If you never want to think about data limits, Truely's unlimited 7-day plan might be worth the splurge. At USD 29.88 (roughly USD 4.20 a day), it's not cheap, but it's built for travellers who depend on strong, consistent data for work, streaming, or hotspot sharing.

Just keep in mind that “unlimited” data often comes with fair-use policies, speeds may drop to ~512 Kbps if you consume more than 5 GB in a single day.

Best eSIM For 30 Days In Taiwan

eSIM	Plan	Price	Data	Price per GB
Eskimo	2-year validity	USD 21	10 GB	USD 2.1/ GB
Zensim	30 days	USD 24	20 GB	USD 1.2/ GB
eSIMTaiwan.com	30 days	USD 73.99	Unlimited	USD 2.46/ GB
Truely	30 days	USD 74.93	Unlimited	USD 2.49/ day

If you're planning light use, the Eskimo 10 GB plan for USD 21 is a solid choice for travellers who stay mostly in cities and don't need high-volume data for streaming or multiple-device tethering.. Its key advantage is the 2-year validity before activation, which allows flexibility if your travel plans change.

This plan runs on partner networks in Taiwan with standard 4G LTE speeds. One thing I find inconvenient is that 10 GB is the highest fixed plan they have. Since it's a fixed-data plan, there is no “unlimited” feature, so once the 10 GB cap is reached, you'll need to top up or purchase another plan.

For moderate users, the Zensim 20 GB plan for USD 24 provides excellent value at roughly USD 1.20 per GB. This plan allows more headroom for navigation, video calls, uploads, and occasional streaming.

The exact Taiwan 30-day plan details are not always fully published, but it operates as a fixed-data plan — meaning you'll lose high-speed access once the 20 GB allowance is used. Zensim is best for travellers who need consistent data without the high cost of an unlimited plan, as long as daily usage stays below heavy thresholds.

For heavy users who need constant connectivity, ESIMTAIWAN.com's Unlimited 30-day plan for USD 73.99 is a great option. It offers nationwide 4G LTE coverage, including remote areas, and supports mobile hotspot. The unlimited plan is subject to a Fair Usage Policy: if usage exceeds approximately 90 GB per month, the provider may temporarily reduce speeds to roughly 0.25–1 Mbps to maintain network quality.

Finally, the Truely Unlimited 30-day plan for USD 74.93 also targets heavy users but adds multi-network access (3G/4G/5G), improving coverage in both cities and rural areas. Its fair-use throttling works differently: if you consume more than 5 GB in a single day, speeds drop to ~512 Kbps for the rest of that day, though your total monthly data remains unlimited.

Truely is ideal for travellers who need broad coverage, but you should be aware that very heavy daily use may significantly reduce speed temporarily.

Best eSIM For Unlimited Data In Taiwan

eSIM	10 days	30 days
eSIMTaiwan.com	USD 35.99	USD 73.99
Truely	USD 36.92	USD 74.93
ZenSim	–	USD 51

ESIMTAIWAN.com Unlimited Plan

It's a data-only plan, so you won't get a local phone number or SMS, but that usually isn't an issue since apps like WhatsApp or FaceTime handle messaging and calls.

Setup is straightforward. Once your phone connects to the network, your plan activates and the 24-hour clock starts ticking. You must activate it within 180 days of purchase, otherwise the plan could expire unused.

Hotspot and tethering are supported, so sharing data with a laptop or tablet is easy. Because of Taiwan's regulations, real-name registration is required — after scanning the QR code, you may need to verify your identity with an ID.

There is a Fair Usage Policy (FUP), meaning the network can throttle speeds in cases of extreme or suspicious usage. In practice, this is rarely an issue unless you're constantly tethering multiple devices, uploading huge files, or streaming in very remote areas.

In my experience, speeds in cities like Taipei, Taichung, and Kaohsiung are smooth enough for streaming, Google Maps, and video calls, and hotspot sharing works without hiccups. Even in smaller towns, connectivity is generally reliable, though signal can weaken slightly in mountainous regions.

What to watch: This isn't “priority unlimited” — extreme data use may trigger throttling, and you won't have a local number for SMS/calls. Otherwise, it's one of the easiest and most reliable unlimited eSIMs for a month in Taiwan.

Truely Unlimited Plan

The Truely unlimited plan is also data-only and offers tethering across 3G, 4G, and 5G networks, with coverage that generally extends from cities into rural areas.

Truely advertises “unlimited” data, but they do have a daily fair usage limit: after roughly 5 GB of data in a single day, speeds may drop to ~512 kbps for the remainder of that day. The exact thresholds aren't officially published, so it can feel a little unpredictable for heavy users.

In my experience, Truely is reliable for moderate daily usage: streaming, navigation, and social media all work fine, and hotspot sharing is smooth for 1–2 devices.

However, if you try to push it – say streaming 4K video while tethering a laptop and tablet — speeds can slow dramatically once you hit the daily limit. In urban areas, coverage is generally solid, but in some remote towns or mountainous regions, speeds may fluctuate.

What to watch: The main drawback is the daily throttling, which makes it less predictable for constant heavy use. You also don't get a local number or SMS, so messaging relies on apps.

If you're planning a mix of city exploration and moderate rural trips, it's workable, but for full-month heavy users, it may feel restrictive compared to ESIMTAIWAN.com.

Zensim Unlimited Plan

If you're staying in Taiwan for a full month and want something stable enough for daily life — from navigating Taipei's MRT to uploading Instagram Stories in Jiufen — ZenSim's unlimited plan is one of the most practical options I've used.

It's a data-only plan (no Taiwanese number), but honestly, that's never been a problem for me. I've been able to call hotels through WhatsApp, message friends on LINE, and even book food deliveries on Uber Eats without needing a local number.

ZenSim allows hotspot sharing, which saved me more than once. I used it to help my friend upload her drone shots from Alishan while we were waiting for the sunrise (signal was surprisingly decent on the viewing deck).

About the Fair Usage Policy, you get full-speed 4G/5G each day until you hit 3GB, and after that speeds go down to roughly 1 Mbps. I hit the limit once on a long train ride from Hualien back to Taipei because I was binge-watching YouTube. After the slowdown, I could still use Google Maps and reply on WhatsApp easily — just not HD video. So if you're not streaming shows all day, you'll hardly notice.

For the price — USD 51 for 30 days, which works out to around USD 1.70/day — it's one of the best long-stay unlimited options if you want reliability without paying premium “tourist rates.”

What to keep in mind: It's not “true unlimited” since speeds slow after 3GB/day, but for normal travel use, it's more than enough. And since it activates on arrival and uses solid 4G/5G networks, it really feels like a plug-and-play solution.

eSIM I Don't Recommend For Taiwan

Eskimo is a reputable eSIM provider with a smooth setup process and reliable network performance, but for a full month in Taiwan, I wouldn't recommend it as my first choice – mainly due to its limited data allowances for the region.

Their Taiwan plans are modest: 10 GB for USD 21, 5 GB for USD 12, 3 GB for USD 9, and 1 GB for USD 4. These are perfectly fine if you only plan to check email, messaging apps, or do occasional Google Maps lookups.

However, for travellers who plan to stream videos, video call, or use a hotspot for multiple devices, 10 GB for a month can be gone in just a few days.

Eskimo does have Asia-region plans with higher data caps — for instance, 30 GB for USD 90, 10 GB for USD 39, 5 GB for USD 25, 3 GB for USD 18, and 1 GB for USD 7.

While these larger plans are more suitable for heavier users, they come at a significantly higher price, which makes them less practical compared to other Taiwan-focused eSIMs like ESIMTAIWAN.com or Truely, which offer unlimited data or larger monthly caps at more reasonable costs.

That said, Eskimo is still a good option for those who want a simple, reliable eSIM and plan to use it lightly. It's also useful as a backup option if you need a secondary connection.

I placed it in this section not because it performs poorly — it works reliably on Taiwan's networks — but because for travellers spending a full month and needing heavy or consistent data use, other eSIMs provide better value and less worry about running out of data.

Detailed Comparisons Of eSIMs For Taiwan

#1 ESIMTAIWAN.com For Taiwan

If you're planning a trip to Taiwan and want a simple, reliable eSIM that just works the moment you land, ESIMTAIWAN.com is one of the best options out there. It runs on Chunghwa Telecom, Taiwan's largest and most trusted network — which means you'll enjoy 4G LTE speeds in 99% of the country.

From the busy streets of Taipei and Kaohsiung to the coastal trails of Hualien and the quieter corners of Tainan, coverage is strong and stable almost everywhere.

Setting it up is a breeze. Once you purchase your plan, the QR code is sent instantly to your email. You can install the eSIM before your flight, and your plan will automatically activate the moment your phone connects to a local network.

Each 24-hour period is counted continuously from that activation point. I found the process extremely smooth — I installed mine at home, landed in Taipei, and was online within seconds after switching off airplane mode. No registration kiosks, no physical SIM swaps — just plug-and-play.

You'll also get a generous 180-day window from the purchase date to activate your eSIM, which is great if you're planning a trip ahead of time or want to buy during a sale. Once activated, it's a one-time prepaid plan — no hidden renewals or surprise charges.

Here are ESIMTAIWAN.com's Taiwan plans

Unlimited Plans

• 1 day – USD 6.99 (USD 6.99/day)

• 30 days – USD 73.99 (USD 2.47/day)

Fixed 5 GB Plan

• 5 GB / 30 days – USD 7.99 (USD 1.59/GB)

Daily 2 GB Plans

• 7 days – USD 7.99 (USD 0.57/GB)
• 10 days – USD 10.99 (USD 0.55/GB)

Things to Consider

• Fair Use Policy (FUP): Although the plan is marketed as “unlimited,” data may be throttled if your usage is flagged as abusive or unusually high — typically after heavy hotspotting or streaming.
• Data-only: No local phone number or SMS is included.
• Device Compatibility: Your phone must be carrier-unlocked and eSIM-compatible. (You can quickly check by dialling *#06# to see if your IMEI appears.)
• Hotspot support: Yes — you can share your connection across devices, which is great if you travel with a laptop or tablet.

During my trip, I used the 30-day Unlimited Plan, and I honestly didn't have to think about data once. Speeds were consistently fast in Taipei, Taitung, and Hualien, even when I used Google Maps, Instagram Stories, and YouTube throughout the day.

I also tethered my laptop a few times for work, and while I did notice a bit of slowdown in the evenings (likely due to network congestion), it never dropped out completely.

The best part? The setup was instant. I scanned the QR code while waiting to board my flight, and by the time I landed, I had full bars of Chunghwa signal. Compared to other eSIMs I've used in Asia, this one was the most seamless – especially because I didn't have to worry about data limits or topping up midway through my stay.

If you're looking for a hassle-free, high-speed connection across Taiwan, this is the one I'd confidently recommend.

#2 Zensim eSIM For Taiwan

If you're heading to Taiwan and want a flexible data-only eSIM with multiple plan options, ZenSim is a solid contender.

You'll connect via Taiwan's top network (Chunghwa Telecom), manage everything via the ZenSim app (easy installation, top-ups available), and you're not locked into huge commitments. Specifically, their Taiwan pricing tiers include:

• 5 GB – USD 15 for 30 days
• 10 GB – USD 17 for 30 days
• 20 GB – USD 24 for 30 days
• Unlimited data – USD 51 for 30 days (note: this one has a daily cap of ~3 GB/day before speed restrictions)

In my experience, the setup was straightforward: I downloaded the ZenSim app, scanned the QR code, installed the eSIM ahead of arrival, and switched to the ZenSim profile when I landed in Taipei.

The app allowed me to monitor data usage and top up if needed, which I appreciated. I felt in control. The 20 GB plan for USD 24 was particularly good value for moderate users who plan to stream a fair amount, use hotspot occasionally, and move beyond just quick browsing.

What I like

• Clear tiered plans you can choose based on your expected usage — nothing too overwhelming.
• Top-up capability means you can start with a smaller plan and scale if your data needs increase.
• Strong network via Chunghwa (good city coverage, stable performance in Taipei, Taichung, Kaohsiung).
• App-based management makes it easy to check usage, install, and handle issues.

Things to watch

The “Unlimited” plan isn't truly unlimited in practice — ZenSim states that their unlimited plan has a 3 GB/day high-speed threshold, after which speeds may be throttled. This means for heavy tethering, streaming multiple devices, or very large uploads you might hit a slowdown.

It's data-only — no local phone number or SMS included. If you need to receive SMS or voice calls in Taiwan (for example, local services, hotel check-in verification), you'll need a separate solution.

While Chunghwa's network is very good in cities and major towns, if you plan to spend long periods in remote mountainous or rural regions, the speed or signal may dip.

The top-up feature is great, but it requires you to monitor your data usage — if you're the type who wants “set it and forget it” you might prefer another provider without daily caps.

If I were going to Taiwan for a month and I predicted moderate to heavy data use (say ~20 GB over 30 days) — streaming, uploading photos/videos, some hotspot use — I would go with the 20 GB plan for USD 24 plan. It gives good value, choice, and control.

However, if I were going to tether multiple devices all day, stream in 4K, or just want total peace of mind without worrying about caps, I might look at the unlimited-type plans from other providers that have fewer daily limitations. ZenSim hits a sweet middle ground for many travellers.

#3 Truely eSIM For Taiwan

Truely has actually become one of my favourite eSIM providers. Their Taiwan plans are straightforward, reliable, and perfect for both short and long stays. You can choose between unlimited and pay-per-GB options, depending on how much data you actually need.

Their unlimited plans range from USD 5.52 for a single day to USD 74.93 for a 30-day plan, which gives you 5 GB/day at full 4G/5G speed before throttling under their Fair Use Policy.

For most travellers, that 5 GB/day is more than enough — during my trip, I streamed music, navigated on Google Maps, uploaded videos, and took Zoom calls without any issues. Once you exceed the daily cap, speeds drop, but basic tasks like messaging and browsing still work fine.

If you prefer a fixed-data option, Truely's pay-per-GB plans are great for lighter users or those wanting tighter budget control:

• 300 MB / 2 days = USD 1.69 (USD 5.63/GB)
• 1 GB / 30 days = USD 3.99 (USD 3.99/GB)
• 5 GB / 30 days = USD 10.99 (USD 2.20/GB)
• 10 GB / 30 days = USD 17.99 (USD 1.80/GB)
• 30 GB / 30 days = USD 28.49 (USD 0.95/GB)

GET 5% OFF with code: belaroundtheworld

One thing I really appreciate is Truely's multi-country functionality – once you've installed the eSIM, you can reuse it in other destinations, not just Taiwan. It's a huge time-saver if you're travelling across Asia and don't want to keep switching eSIM profiles.

In terms of coverage, Truely uses top-tier local networks (mainly Chunghwa and Taiwan Mobile), so you'll get excellent 4G/5G data in cities like Taipei, Kaohsiung, and Taichung, plus stable connections in smaller towns and rural areas. During my stay, speeds were consistently high in urban spots, though they did dip slightly in more remote mountain regions — still usable for navigation and messaging.

Setup is also one of the smoothest I've tried: after purchasing, I got my eSIM QR code instantly via email, scanned it before my flight, and was online within minutes after landing at Taoyuan Airport. The whole process took less than five minutes.

A few things to keep in mind:

Truely's “unlimited” plans do throttle speeds after 5 GB/day, so if you're streaming 4K video or using your phone as a hotspot for multiple devices all day, you'll notice the slowdown.

These are data-only plans — no local number or SMS, though WhatsApp, LINE, and iMessage work perfectly fine for calls and texts.

If you move between countries frequently, you'll appreciate the reuse feature, but make sure to double-check regional compatibility before travelling.

Overall, Truely strikes the ideal balance between reliability and flexibility. It's not the cheapest eSIM, but for remote workers or heavy data users like me, the peace of mind is worth every cent. I never had to worry about finding Wi-Fi or running out of data mid-trip — and that's exactly what you want when exploring Taiwan.

#4 Eskimo eSIM For Taiwan

If you're planning a trip to Taiwan and want a simple data-only eSIM without committing to “unlimited” pricing, Eskimo might fit the bill. Their Taiwan-specific packages are while quite modest in allowance, still usable for lighter data use:

Here are Eskimo's Taiwan plans:

• 10 GB – USD 21 (USD 2.10/GB)
• 5 GB – USD 12 (USD 2.40/GB)
• 3 GB – USD 9 (USD 3.00/GB)
• 1 GB – USD 4 (USD 4.00/GB)

If you're looking for more data or multi-country use, Eskimo also offers their Global coverage plans that include Taiwan and up to 109 countries:

• 30 GB – USD 90 (USD 3.00/GB)
• 10 GB – USD 39 (USD 3.90/GB)
• 5 GB – USD 25 (USD 5.00/GB)
• 3 GB – USD 18 (USD 6.00/GB)
• 1 GB – USD 7 (USD 7.00/GB)

What Eskimo offers:

• The Taiwan plans are valid for country use (not multi-country) and support data-only (no local Taiwanese phone number or SMS service) for Taiwan.
• They support mobile hotspot/tethering (so you can share the data with other devices) in many cases.
• The global plans include long validity (e.g., some mention validity of up to 2 years for multi-country usage), which means you could buy now and use later or travel more than once.
• Setup is straightforward: after purchase, you're delivered a QR code, install the eSIM, and you're connected.

What to keep in mind (and my user-experience input):

While Eskimo is a reliable brand, for a full month in Taiwan with moderate or heavy data use, the Taiwan-specific plan sizes are fairly small. If you plan to stream video, tether a laptop + phone, use maps heavily every day, or upload content, 10 GB may not last the full 30 days. In one review I saw:

“Eskimo does not provide an unlimited data plan for Taiwan. Fixed-data plans may be more economical for most travelers, while very heavy users might still need to consider additional data purchases.”

Because of that, I place Eskimo in the “good backup / light-use option” category, rather than the best pick for heavy users staying a month.

If you choose Eskimo: pick the highest tier (10 GB) and plan your usage carefully (e.g., hotspot lightly, stream only when WiFi not available). Also the global plan option gives extra flexibility if you travel beyond Taiwan.

If I were going to Taiwan and expected light to moderate data use (e.g., lots of WiFi available, only occasional uploads or streaming, mostly city-based), I might use Eskimo — the 10 GB for USD 21 isn't bad.

But if I was planning to stay for 30 days, move between cities and countryside, hotspot multiple devices, or stream regularly, I'd opt for a plan with more generous allowance or no data worry at all (like those labelled “unlimited” by other providers). Eskimo is solid, but its Taiwan plans are limited by allowance, so your expectations should match your usage.

Choosing The Best eSIM For Taiwan

What Is The Cheapest eSIM For Taiwan?

The cheapest eSIM really depends on how much data you need and how long you're staying.

• For a 1 GB plan: Eskimo is one of the lowest at just USD 4 (USD 4/GB).
• For a 5 GB plan: Eskimo again offers a solid budget option at USD 12 (USD 2.40/GB).
• For a 10 GB plan: Zensim takes the lead at USD 17 (USD 1.70/GB) for 30 days, running on Taiwan's top-tier Chunghwa network.

If you're only visiting Taiwan for a short trip and need light data for Google Maps, messaging, and social media, Eskimo's smaller plans are the most budget-friendly. They're simple, prepaid, and get you connected quickly.

But if you're staying longer or want enough data for navigation, streaming, and uploading photos, Zensim's 20 GB plan for USD 24 (USD 1.20/GB) offers the best value overall. It's a great middle-ground—affordable, generous in data, and backed by reliable Chunghwa coverage across the island.

Most Reliable eSIM For Remote Areas In Taiwan

If you're planning to go beyond Taipei — maybe hiking the misty trails of Alishan, cycling around Sun Moon Lake, or exploring the rugged east coast near Hualien and Taitung — you'll want an eSIM that stays strong even in the most remote corners. My top pick for this is ESIMTAIWAN.com, and here's why.

Unlike many international eSIMs that depend on roaming networks, ESIMTAIWAN.com connects directly to Taiwan's top local providers, including Chunghwa Telecom, which offers the widest 4G and 5G coverage in the country. This direct connection means fewer dropouts and smoother data performance when you're on mountain roads, in rural towns, or travelling between cities.

While their 30-day unlimited plan at USD 73.99 may sound steep, it's an excellent choice if you're staying long-term or need a guaranteed signal for work, maps, or translations on the go.

But if you're visiting Taiwan for a shorter trip, their daily 2 GB Plans are surprisingly affordable:

• 3 days – USD 4.99
• 5 days – USD 6.99
• 7 days – USD 7.99
• 10 days – USD 10.99

These short-term plans are ideal for travellers who don't need unlimited data but still want reliable, high-speed internet wherever they go. With ESIMTAIWAN.com, you're essentially paying for local-level reliability — consistent coverage that even remote regions can count on.

How To Get An eSIM For Taiwan

Getting an eSIM for Taiwan is incredibly easy — and once you've done it, you'll wonder why you ever queued at airport SIM counters. The process takes just a few minutes and saves you a lot of hassle on arrival. Here's how it works:

1. Choose the right eSIM provider for your trip

If you're mostly staying in cities like Taipei, Taichung, or Kaohsiung, affordable options like Eskimo eSIM are perfect for casual browsing, navigation, and messaging.

But if you're venturing into rural or mountainous areas, such as Alishan, Taroko Gorge, or Sun Moon Lake, you can consider using ESIMTAIWAN.com, as it connects directly to Chunghwa Telecom, Taiwan's largest and most reliable local network.

2. Select your data plan

Think about how much data you'll actually use. A 1–3 GB plan is fine for short trips or light use (maps, WhatsApp, and translation apps). Go for 5–10 GB if you plan to share photos, stream, or use Google Maps frequently.

For longer stays or heavy users, ESIMTAIWAN.com even offers Daily 2 GB plans (from USD 4.99) or a 30-day unlimited plan for worry-free connectivity.

3. Purchase online & get your QR code instantly

Once you've picked your provider and plan, checkout is quick and completely digital. Within seconds, you'll receive a QR code by email — no need to visit a store or wait in line at the airport.

4. Install before your flight & activate on arrival

You can install your eSIM profile while still at home (just don't activate it yet). As soon as your plane lands in Taoyuan, Kaohsiung, or Taichung Airport, simply switch on data roaming — and you'll be connected within minutes.

That's it — no fumbling with SIM cards or dealing with local kiosks. With your eSIM ready, you can immediately check in with your hotel, book your EasyCard for transport, or find the best bubble tea spot near you.
