The esima eSIM worked flawlessly throughout my stay in Taipei. Installing it was a breeze — just scanned the QR code provided, and I was online in less than a minute! Great speeds for streaming and navigation. Highly recommend!

I had high hopes for the esima eSIM in Taiwan, but the setup process was confusing. It took me longer than expected to get it working, and the connection speed in rural areas was disappointing. The app could use some improvements.

Using esima in Taiwan was great, especially in Taipei. Connection was quick and reliable in tourist spots. I did face some slow speeds in more rural locations, but overall, it was a hassle-free experience.

Setting up the esima eSIM was a breeze, took less than 30 seconds! The 4G speed was more than adequate for navigation and social media while exploring the beautiful streets of Taipei. Would definitely use it again!

I was pleasantly surprised by how well the eSIM performed in Taiwan. Easy setup with a QR scan, and it worked flawlessly in Taipei and Tainan. Just a bit iffy in some remote areas. Overall, a solid choice for anyone looking to stay connected while traveling.

I found the eSIM from esima to work well in the cities, but it struggled in more remote parts of Taiwan. Upload speeds dropped significantly outside of Taipei. The installation process was straightforward though, which was a plus.

I loved using esima during my trip! The coverage was excellent, especially in Taipei and Tainan. No slowdowns when using maps, and I downloaded a few podcasts over 5G without any issues. Will use again for my next adventure!
Typical home-carrier roaming

Flat rate
Most international carriers charge a flat daily rate for Taiwan roaming — typically the first gigabyte or two runs at full speed, then throttles to 128 or 256 kbps for the rest of the day. Hotspot is often blocked or costs extra.
You pay that daily fee whether you use 50 MB checking email or 2 GB navigating all day, and the clock resets at midnight in your home time zone, not Taiwan time, so a late-night arrival can burn two days of charges in twelve hours.
An esima eSIM gives you a fixed data pool at local-market pricing with no throttling and no daily recurring fee — you know the total cost before you leave home. Hotspot works from install, so you can tether a laptop on the THSR or share with a travel partner.
The eSIM keeps your original number active for two-factor SMS and incoming calls while the Taiwan line handles all data, which matters when your bank or airline sends a verification code mid-trip.
Different trip, same eSIM — here is how it lands for the most common visitors to Taiwan.
You bounce between Shilin, Raohe, and Ningxia night markets, splitting bills with LINE Pay and EasyCard mobile at every stall. The eSIM keeps QR codes loading in real time, so you pay for stinky tofu, unlock a YouBike to the next district, and never queue at a 7-Eleven ATM.
Night-market hopper
You rent a scooter in Hualien and ride the Suhua Highway to Taroko Gorge. The eSIM holds signal in Hualien city and patches of the coast, but you download offline maps before leaving because the tunnels and gorge walls kill coverage for long stretches. Chunghwa Telecom reconnects faster than the other carriers when you emerge.
East-coast road-tripper
You base in Taipei and day-trip to Tainan, Taichung, and Kaohsiung by High Speed Rail. The eSIM runs on Chunghwa Telecom inside the tunnels, so you video-call home, finish work emails, and book your next Airbnb without losing connection between cities.
THSR commuter
The apps locals and travelers actually use — the ones that need real cell data, not just hotel Wi-Fi.
EasyCard mobile
NFC payments for MRT gates, buses, convenience stores — requires live backend validation
YouBike 2.0
QR unlock for public bike-share stations across Taipei, Taichung, Kaohsiung
LINE Pay
QR payments at night markets, restaurants, street vendors
Taiwan Rail (台鐵e訂通)
Book and retrieve QR tickets for TRA local trains
Google Maps
Live navigation, MRT routes, bus times, walking directions
Uber
Rideshare in Taipei — limited outside the capital
~40 MB per day for text and photo chats, ~120 MB per day with regular voice calls, ~300 MB per day with video calls.
Maps
~80–150 MB per day for live navigation in Taipei or along the west-coast cities; cache offline tiles for Taroko and the east coast to save data.
Rideshare
~5–10 MB per ride for Uber in Taipei; YouBike 2.0 unlocks use ~1–2 MB per session including the QR handshake and GPS lock.
Typhoon season runs June through October, with peak landfall risk in July and August. Heavy rain and wind can damage cell towers along the east coast and in mountain areas; Chunghwa Telecom restores service fastest, but expect intermittent outages in Hualien, Taitung, and Alishan during and immediately after a direct hit.
The THSR and Taipei Metro maintain coverage through most storms, but surface transit and rural highways may lose signal if towers go offline. Download offline maps and cache hotel details before a typhoon warning is issued.
You get full signal on platforms and in stations, but tunnels between stops have no coverage on any carrier. Messages and map tiles load while the train is stopped; they queue or fail between stations. Download your route before you board.
Taroko's tunnels and the Suhua Highway have patchy 4G on all carriers. Chunghwa Telecom performs best but you will still hit long dead zones. Download offline maps and cache any trail info before you leave Hualien city.
Yes. Chunghwa Telecom maintains full 4G inside tunnels along the entire THSR route. Taiwan Mobile and FarEasTone may drop briefly in the longest tunnel sections between Taichung and Tainan, but coverage is strong overall.
Yes. EasyCard mobile needs live cell data for every MRT gate tap and convenience-store payment — the app validates with backend servers in real time. Wi-Fi alone will not work. Keep the eSIM active whenever you plan to scan.
Budget 1–2 GB if you rely on hostel Wi-Fi and only use maps and rideshare apps on the move. Plan for 3–5 GB if you stream music, browse social feeds, and video-call home. Heavy users who upload photos and watch video daily should start at 8–10 GB.
Yes. YouBike 2.0 stations require app-based QR unlocks with live data. The older 1.0 kiosks accept only physical EasyCard, so stick to 2.0 racks if you are relying on the app and eSIM.
Both deliver strong 5G in Kaohsiung metro areas. Chunghwa has a slight edge in the older Zuoying district and along the MRT Red Line. Taiwan Mobile is faster in newer developments around the Exhibition Center. You will not notice a practical difference downtown.
Yes. WhatsApp voice and video calls work over the eSIM's data connection. Your original number stays active for SMS and incoming calls, so you can receive two-factor codes and answer your home-carrier line while WhatsApp runs on the Taiwan data line.
Hualien and Taitung cities have solid LTE on all carriers. Taiwan Mobile and FarEasTone thin to LTE-only in these eastern counties; Chunghwa holds 4G more consistently. Venture into Taroko Gorge or the coastal mountains and you will hit long stretches of weak or no signal.
Yes. LINE Pay and most Taiwan QR payment apps need live data to validate transactions. The eSIM provides the cell connection required for real-time authorization at night markets, convenience stores, and street vendors.
A physical SIM from the Chunghwa or Taiwan Mobile counter costs about the same and gives you identical network access. The trade-off: you wait in line, swap out your home SIM (losing your original number unless your phone has dual-SIM), and need a SIM tool. The eSIM installs in two minutes, keeps your home number active for SMS, and you delete it when you leave.
Sun Moon Lake resort zones have 3G-only coverage on Taiwan Mobile and FarEasTone. Chunghwa Telecom holds LTE in the main village areas but thins to 3G on the lakeside trails and higher elevations. Download maps and cache any booking confirmations before you leave Taichung.
Chunghwa Telecom has stronger and more consistent 4G along the Suhua Highway and in Taroko Gorge. FarEasTone thins to LTE-only in Hualien County and struggles more in tunnels. If you are spending most of your trip on the east coast, Chunghwa is the safer bet.
Yes. Hotspot is enabled by default. Chunghwa Telecom maintains full 4G inside THSR tunnels, so you can work or stream from Taipei to Kaohsiung without drops. Other carriers may lose signal briefly in the longest tunnel sections.
Alishan mountain roads have 3G-only coverage on Taiwan Mobile and FarEasTone. Chunghwa Telecom holds LTE in the main tourist areas near the railway station but thins to 3G above 2,000 meters. Expect slow speeds and intermittent signal on the forest trails.
Going further than Taiwan? These plans include Taiwan plus everywhere in between.
Taiwan runs on apps — EasyCard mobile for every MRT gate and 7-Eleven payment, YouBike 2.0 QR unlocks at 1,200+ stations, LINE Pay at night markets. A Taiwan eSIM drops you onto Chunghwa Telecom or Taiwan Mobile's network the moment you clear Taoyuan immigration, so you scan your way through Taipei Metro, unlock a bike outside Taipei Main Station, and split the bill at Din Tai Fung without hunting for a SIM counter or toggling airplane mode to dodge roaming fees.
Balanced use — social, navigation & light streaming
How many travelers?
Landing at Taoyuan or Songshan with an esima eSIM means you walk past the Chunghwa Telecom counter, scan the Airport MRT QR at the gate, and message your Airbnb host before the train leaves the platform. Installation takes two minutes: open the QR we email, tap Add Cellular Plan, toggle the new line to Primary.
The eSIM registers on whichever of the three carriers — Chunghwa, Taiwan Mobile, FarEasTone — offers the strongest signal at your location, then hands off automatically as you move.
In Taipei you will see 5G most of the time; step into a basement dumpling shop or the older sections of Ximending and it drops to LTE, which still runs at 20–40 Mbps. The High Speed Rail is fully wired on Chunghwa, so you can video-call from Taipei to Kaohsiung without a drop.
East-coast routes are different: the Suhua Highway hugs cliffs and tunnels where all carriers struggle, and Taroko Gorge's marble walls block signal in long stretches. Hualien city itself has solid LTE; venture into the gorge and you will toggle between one bar of 4G and nothing.
A physical SIM from a 7-Eleven gives you the same network access at a similar price, but you surrender your home-carrier slot, wait in line to activate, and need a SIM tool.
The eSIM keeps your original number active for two-factor SMS while the Taiwan line handles data, and you can delete it the moment you board your departure flight.
Three reasons travelers pick esima for Taiwan. First: pricing mirrors local prepaid rates, not the international roaming markup your home carrier layers on top of wholesale access.
Second: the eSIM hands off between Chunghwa Telecom, Taiwan Mobile, and FarEasTone automatically, so you get the strongest tower whether you are in a Taipei basement food court or on the THSR between Taichung and Tainan.
Third: hotspot is enabled from install — critical if you are traveling with a laptop, a tablet, or a companion whose device does not support eSIM. No throttling after an arbitrary threshold like some carrier bundles impose.
Your QR code lands in your inbox minutes after purchase.
Pay one upfront price — no surprise charges abroad.
Your physical SIM stays active for calls and texts.
Connect to top-rated local networks at full speed.
Real humans ready to help, any time zone, any day.
Scan once and you're online — no app, no SIM swap.
Our Taiwan eSIMs connect to Chunghwa Telecom, Taiwan Mobile, and FarEasTone. Chunghwa delivers the most reliable 4G and 5G along the entire Taipei Metro network and High Speed Rail corridor, including inside tunnels between Taichung and Tainan where other carriers briefly drop.
Taiwan Mobile and FarEasTone offer strong 5G in Taipei, Taichung, and Kaohsiung metro areas but thin to LTE in Hualien and Taitung. Taroko Gorge's tunnels and the Suhua Highway coastal stretch have patchy 4G on all carriers; Chunghwa performs best but expect intermittent signal.
Alishan mountain roads and Sun Moon Lake resort zones fall back to 3G on smaller carriers. The THSR maintains full 4G in tunnels on Chunghwa; other networks may lose signal briefly in the longest sections.
