Roami is a global eSIM carrier focused on travel connectivity. This guide is compiled from network data, official carrier and manufacturer documentation, and traveler inquiries.
📑 Table of Contents
A Taiwan eSIM can be genuinely unlimited and bought before you fly — one of the few destinations where both are true, because the local operators themselves sell unlimited tourist data as instant digital profiles. This guide covers who sells what, which network wins where, and how to get connected the moment you clear customs.
Quick answer: For most travellers in Taiwan, the local networks are the comfortable pick; a travel eSIM suits tighter budgets and city-only trips. Start with the eSIM compatibility quiz: the one step Taiwan travellers skip and pay for later.
The verdict up front: Chunghwa Telecom is the overall performance leader — Ookla’s H2 2025 Taiwan report measured a 346 Mbps median 5G download and 94.5% consistency on its network, the best on the island. Taiwan Mobile is the strong urban all-rounder, and FarEasTone posts serious 5G speed (257 Mbps median) at budget-friendly prices. Buy your Taiwan, China eSIM online before departure, install it at home, and skip the Taoyuan Airport queue entirely. Test the setup risk-free with a no-cost trial eSIM, then apply code WEB20 for 20% off your first plan.
What makes Taiwan an easy eSIM destination
Most destinations force an ugly trade-off: expensive day-rate roaming, a physical SIM hunt at the airport, or a throttled “unlimited” plan that collapses after 2 GB. Taiwan breaks the pattern in two ways.
First, the three national operators — Chunghwa Telecom, Taiwan Mobile and FarEasTone — all sell tourist packages directly, several of them as instant digital profiles with no in-person passport presentation. Buying a local-class plan from abroad is normal here, not a workaround.
Second, the island is small, densely populated and heavily built-out, so coverage gaps are rare and narrow. Per Ookla’s August 2026 global index, the median mobile download sits at 110.74 Mbps, ranking 44th worldwide — comfortably above the 109.05 Mbps global median, and that figure drags down for mountain trails, not for cities. Cable.co.uk’s pricing survey puts 1 GB of local data at about USD 0.69, 71st of 237 markets against a USD 2.59 global average.
If you have not yet confirmed that your handset supports digital SIM profiles at all, run it through the phone compatibility list first — everything else in this guide assumes that box is ticked.
There is a third difference that matters for how you buy: the operators here sell through channels most destinations do not have. Convenience stores — which are genuinely everywhere — handle top-ups for operator-direct plans, reseller platforms pre-sell genuine carrier profiles to tourists abroad, and airport desks register a line in five minutes. The result is a market where the hard part is not access but choice: too many legitimate routes, each with slightly different pricing, identification requirements and activation timing. This guide’s job is to collapse those routes into the Taiwan eSIM that matches your trip.
Chunghwa, Taiwan Mobile and FarEasTone: the networks compared
| Chunghwa Telecom | Taiwan Mobile | FarEasTone | |
|---|---|---|---|
| Median download, all technologies | 142.62 Mbps | 90.08 Mbps | Solid urban speeds |
| Median 5G download | 346 Mbps | Competitive urban 5G | 257.01 Mbps |
| Latency | 27 ms (21 ms on 5G) | Low, call-friendly | Acceptable for daily use |
| Consistency | 94.5% of samples ≥5 Mbps down | Strong in cities | Good where built out |
| Best for | Rural coverage and raw speed | City stays and video calls | Budget-conscious 5G |
All three figures come from Ookla’s Taiwan Speedtest Connectivity Report for H2 2025, measured across real consumer tests rather than lab conditions.
One more row belongs under the table: all three operators sell unlimited-data tourist tiers — 3 to 30 days, physical or eSIM — which is the structural fact that makes this market different, and the subject of the deep dive below. There is no “wrong” network in the cities; the tiers differ most in the mountains, on the east coast and at the checkout.
Chunghwa Telecom: the default for most itineraries
Chunghwa holds the largest spectrum position in 5G and the widest rural footprint, and the numbers back the reputation: a 346 Mbps median 5G download, 19.23 Mbps median upload, and the island’s best consistency score at 94.5%. Practically, that means Chunghwa is the network you want beneath you on the Alishan mountain road, along the east coast toward Hualien, and everywhere a rented car takes you off the high-speed rail spine. City performance is excellent too — Taipei recorded the country’s fastest urban mobile median at 130.78 Mbps.
A Taiwan eSIM that can select Chunghwa covers roughly 90% of the “which network is best here” question in one decision.
Taiwan Mobile: best in the cities
Taiwan Mobile posts the second-fastest overall median (90.08 Mbps) and behaves well in the dense, interference-heavy environments that actually stress a phone: Ximending at rush hour, the Fengjia night market in Taichung, the underground MRT platforms. Uploads hold up for video calls, which matters if you are working from a café for a week rather than sightseeing. If your entire trip is Taipei–Taichung–Kaohsiung by high-speed rail, the network differences between Taiwan Mobile and Chunghwa will rarely be visible; consistency indoors is where Taiwan Mobile quietly earns its keep.
Who has Taiwan’s strongest 5G?
FarEasTone’s 257 Mbps median 5G download is not a budget-tier number — it outpaces Taiwan Mobile’s overall median by nearly 3x. The operator absorbed Asia Pacific Telecom’s network (the T STAR brand) at the end of 2023, which expanded its spectrum holdings and its coverage outside the biggest cities. For tourists, FarEasTone is the value pick: fast enough for anything you will realistically do, usually priced below the other two. Tainan, the Kenting coast and Sun Moon Lake all sit inside its comfortable zones.
The price split: local SIM vs travel eSIM
The tourist tariff is where the market’s generosity becomes concrete. Chunghwa publishes two unlimited-data tourist ladders — 4G and 5G — and the pricing quirk everyone discovers on arrival is real: the 5-day plan costs the same as the 3-day one.
Chunghwa 4G unlimited tourist plans, per the carrier’s tourist tariff tracked by Roafly:
| Validity | Price | Approx. USD | Included voice credit |
|---|---|---|---|
| 3 days | NT$300 | ~$9 | NT$100 |
| 5 days | NT$300 | ~$9 | NT$50 |
| 7 days | NT$500 | ~$16 | NT$150 |
| 10 days | NT$500 | ~$16 | NT$100 |
| 15 days | NT$700 | ~$22 | NT$100 |
| 30 days | NT$1,000 | ~$31 | NT$430 |
Chunghwa 5G unlimited tourist plans (same tariff sheet; USD approximations per Taiwanderers’ airport price check):
| Validity | Price | Approx. USD |
|---|---|---|
| 3 days | NT$500 | ~$16 |
| 5 days | NT$600 | ~$19 |
| 7 days | NT$800 | ~$25 |
| 10 days | NT$1,000 | ~$31 |
| 15 days | NT$1,200 | ~$37 |
| 30 days | NT$1,600 | ~$50 |
The 4G ladders are described by the carrier as genuinely unlimited on the handset; the 5G cards carry the tethering catch noted below — published hotspot allowances of 3, 5 and 7 GB on the 3-, 5- and 7-day tiers respectively. Note also that two products with the same day-count are not always identical: some validities have higher-priced variants with more voice credit, so read the full line item rather than the day number.
Taiwan Mobile’s tourist ladder, per its tariff notice scheduled through the end of 2026, runs promotional pricing below list: NT$300 for 3 or 5 days (listed NT$400), NT$450 for 7 days (listed NT$550) and NT$500 for 10 days (listed NT$700), each combining unlimited domestic data with communication credit. Its reservation system can show pickup prices below even the promotional tariff — check at booking time rather than treating any of these as permanent.
FarEasTone publishes 3-to-30-day tourist packages in the same unlimited-data shape, typically priced at or below the other two; reseller listings have shown 4G tourist packages from around US$7.45 for the shortest durations, per a 2026 Taiwan SIM roundup. Purchases there require two forms of identification — a passport plus a second document such as a license, visa or entry permit — so carry a backup.
Buying a Taiwan eSIM or tourist plan as a visitor, three routes:
-
Pre-buy through a reseller (recommended for most). Klook and KKday sell genuine Chunghwa eSIMs and physical-SIM vouchers that you install or redeem on arrival; Chunghwa’s own online reservation system has been suspended, making resellers the de facto online route, with prices tracking the counter closely.
-
Airport counter. All three operators staff Taoyuan’s arrival halls; registration takes one passport and about five minutes, and the desks shut around 9:30 p.m. — which turns a red-eye landing into a morning queue. Short-stay eSIM and physical SIM cost the same at the desk.
-
City store. Taiwan Mobile and FarEasTone take walk-up tourist applications at physical stores, with payment in New Taiwan dollars, by card, or via UnionPay and Alipay.
Whichever route you pick, the real-name rule applies: a passport number is registered at purchase, digitally online or physically at the desk, under National Communications Commission rules.
What each plan costs
Taiwan’s tourist plans are famous for the word “unlimited,” and the fame is mostly deserved — but read two clauses before you buy.
Daily high-speed allowances. Some unlimited tiers run full speed all month; others include a large high-speed bucket (often in the tens of gigabytes) and then throttle for the remainder of the validity period. A two-week trip that streams video nightly can chew through a high-speed bucket; a map-and-messaging trip will never notice it. Match the clause to your usage, not the marketing word.
Hotspot sharing. Unlimited tourist plans commonly permit personal hotspot, but some cap tethered speed or the number of devices. If your laptop depends on the phone’s connection, verify the tethering clause in the plan description before checkout rather than discovering it at your hotel.
What to verify before checkout, as a list:
-
Whether the tier is truly unmetered or runs a high-speed bucket with throttling after it
-
The tethering allowance, if any — Chunghwa’s 5G cards publish explicit 3–7 GB hotspot buckets
-
Whether the validity counts 24-hour periods from activation or calendar days
-
What identification the purchase route requires — one passport at most counters, two documents at FarEasTone
-
Where top-ups happen for your specific product: operator app, convenience store, or provider dashboard
The safe pattern: buy a modest unlimited Taiwan eSIM for the phone, and treat anything bigger than navigation-plus-social as a reason to step up one tier rather than to tether aggressively.
What the Chunghwa 4G ladder costs per day, if you price it that way:
| Duration | Price | Cost per day |
|---|---|---|
| 5 days | NT$300 | NT$60 (~US$1.90) |
| 10 days | NT$500 | NT$50 (~US$1.60) |
| 15 days | NT$700 | NT$47 (~US$1.50) |
| 30 days | NT$1,000 | NT$33 (~US$1.00) |
The per-day cost falls as the duration rises, which is the polite way of saying the long tiers are underpriced: a month of unlimited Taiwanese data costs about what a single day of roaming does on many home carriers. It also explains why the short tiers are the ones that sell out of stock first — the arbitrage runs the other way.
Where to Buy an eSIM
Buying your Taiwan eSIM online before departure wins on almost every axis. You install the profile on home Wi-Fi, land connected, and never touch an arrivals-hall counter. The mechanics are covered in our step-by-step activation walkthrough — scan, label the line, set it as your data line, enable data roaming.
The Taoyuan Airport counters still work, with caveats. All three operators staff arrivals-hall desks, and staff are used to passport-based sign-ups that take minutes. But you land into a queue alongside every other flight’s arrivals, counter hours compress late at night, and the desk plans skew physical-SIM. If your flight lands after midnight, an online-bought profile is not a luxury — it is the difference between navigating the airport MRT and standing in a taxi line doing nothing.
If you do use the airport desks, the flow compresses to four steps:
-
Pick the operator’s desk in the arrivals hall — Chunghwa, Taiwan Mobile and FarEasTone are all represented
-
Hand over your passport (plus the second ID if FarEasTone) and choose your validity
-
Pay — NT$ cash, card, UnionPay or Alipay depending on the desk
-
Let staff install the SIM or eSIM and confirm data works before you walk away
One registration note: local carriers operate under National Communications Commission (NCC) rules that require real-name verification for SIM products. Tourist plans handle this with a passport number at purchase — digital or at the counter — so have your passport handy either way.
A sample Taiwan week, connectivity day by day
| Day | Where you are | What the network needs to do | What to expect |
|---|---|---|---|
| 1–2 | Taipei: 101, the MRT, night markets | Indoor 5G, transit apps, payments | Excellent on all three networks; MRT platforms stay connected |
| 3 | High-speed rail to Taichung, Sun Moon Lake | 300 km/h browsing, lakeside coverage | HSR runs connected nearly end to end; the lake’s shore holds signal |
| 4 | Alishan: sunrise, forest trails | Mountain roads, early-morning uploads | Chunghwa is the safe choice; gaps appear above the tree line |
| 5 | Tainan’s old city | Temples, food-street maps | All networks comfortable; FarEasTone is well priced here |
| 6 | Kaohsiung: Pier-2, the harbour | Urban 5G, streaming | Strong citywide; evening riverside congestion is mild |
| 7 | Kenting or the east coast | Beach towns, coastal roads | Towns covered; empty coastal stretches thin out |
Two structural notes the table cannot show. The high-speed rail corridor along the west coast is the most reliably connected strip on the island — you can work from the train the whole way. And Hualien and the east rift valley are covered in the towns but not continuously between them, so download offline maps before driving Highway 11 or the Suhua Highway. If Taroko Gorge is on your list, check current access status first — large sections have remained closed since the April 2024 earthquake, and coverage inside the gorge was never continuous.
Which Taiwan plan matches your trip
| Your trip | Best fit | Why | Watch for |
|---|---|---|---|
| Taipei long weekend, 3–4 days | NT$300 Chunghwa 4G tier or a travel eSIM | The cheapest tier already covers the stay | Airport desks close around 9:30 p.m. |
| One-week classic loop by HSR | 7-day NT$500 4G plan | Unlimited data for the full circuit | The 5-day tier costs the same NT$300 — size up when it fits |
| Alishan and central-mountain drives | Chunghwa-network plan | Best rural footprint and consistency | Gaps above the tree line on any network |
| East coast: Hualien and Taitung | Chunghwa plus offline maps | Towns covered, stretches between are not | Download Highway 11 and Suhua sections first |
| Two-week deep dive | 15-day NT$700 4G tier | About US$22 for two unlimited weeks | Hotspot clause if tethering a laptop |
| Month of remote work | 30-day NT$1,000 tier or the 5G ladder | A real month of unlimited data for ~US$31 | 5G tiers cap tethered data separately |
| Night-market food tour, heavy social video | Any unlimited tier | Usage only matters if the fair-use clause says so | Read the clause, not the marketing word |
| Family, multiple devices | One profile per phone | Cheaper and more resilient than consolidating | Each purchase registers one passport |
| Kaohsiung and the Kenting coast | Taiwan Mobile or FarEasTone tier | Southern cities are well served by all three | Empty coastal stretches thin out |
Regional Coverage
| Area of Taiwan, China | What to expect | The honest caveat |
|---|---|---|
| Taipei and New Taipei | Dense 5G, connected MRT platforms, strong indoors | The island’s densest network environment |
| HSR west corridor | Signal along nearly the whole run | Handovers at 300 km/h can drop a session briefly |
| Taichung, Tainan, Kaohsiung | Strong urban 5G and 4G on all three networks | Night-market crowds stress uploads, not downloads |
| Alishan and the central mountains | Chunghwa leads; towns and the main road covered | Gaps above the tree line and on side roads |
| Sun Moon Lake and Nantou | The shoreline holds signal well | Interior valley roads thin quickly |
| Suhua Highway (Su’ao–Hualien) | Long known dead stretches between towns | Download the entire route before driving |
| East rift valley (Hualien–Taitung) | Towns covered, valleys between are not | Highway 9 sections go dark between townships |
| Kenting and the south coast | The resort strip is well covered | Beyond the strip, the coast empties out |
| Outlying islands (Penghu, Kinmen, Matsu, Green Island, Lanyu) | Town centers covered, ferries and remote coasts are not | Coverage is town-anchored on every island |
Read the table as a whole and the shape of the island’s coverage appears: the western urban spine is effectively saturated, the mountains and east coast are town-and-corridor coverage with real gaps between, and the outlying islands are anchors only. A single profile that can select Chunghwa covers the mountain and east-coast cases; the ferry gaps and high-mountain dead stretches belong to geography, not to any plan.
Getting around: the apps that need your eSIM data line
Taiwan’s transport stack runs on your phone more than most destinations:
-
HSR booking and tickets — book in the official app and collect with a code; having data at the platform beats hunting station Wi-Fi
-
EasyCard top-up — the tap-to-ride card covers metro, buses and convenience stores; the app keeps the balance visible
-
YouBike — the public bike system in every major city unlocks and returns through an app that wants a live connection
-
Google Maps — works superbly, but cache offline areas for Alishan, the east coast and any national-park day
None of these are heavy, but all of them punish a dead data line. It is the quiet argument for installing your Taiwan eSIM before you fly rather than configuring it in an arrivals hall.
Data expectations for a Taiwan trip run lighter than most destinations because the apps are efficient and the cities offer café Wi-Fi everywhere. A realistic budget: roughly 500 MB per heavy city day for maps, transit apps, messaging and payments; 1–2 GB on days that include train streaming or video calls; and very little on mountain and east-coast days, where the offline maps you downloaded are doing the work. Even the shortest NT$300 tier dwarfs those numbers — which is why the market’s honest advice is that data anxiety does not belong in Taiwan, China.
Taiwan typhoon season and what it does to mobile connectivity
July through October is typhoon season, and a direct hit takes chunks of the network down with the power grid — usually for hours in cities, occasionally for days in mountain and coastal townships. Two practical habits: keep an offline map of your current city downloaded through the season, and if a typhoon warning is active, expect 4G instead of 5G and occasional congestion rather than no signal at all. The networks recover fast; your plans should be the flexible part.
One regional note worth knowing during the season: the outlying islands’ links to the mainland grid are the fragile edges of the system, so Green Island, Lanyu and parts of Penghu recover slowest after a storm. If your itinerary includes them in typhoon months, treat the day after the storm as offline by default and let any surprise of working signal be a pleasant one.
Practical checks the night before a warned storm: charge everything, download tomorrow’s maps and tickets, screenshot your bookings, and withdraw some cash — the card terminals fail with the same power the towers do. Fifteen minutes of preparation covers the most common week-long disruption this region produces.
Installing and troubleshooting your Taiwan, China eSIM
Setup is the standard remote flow: purchase, receive the QR code or one-tap install link, add the line in Settings, set it as your data line, enable data roaming. Do it at home. In settings terms, the full sequence is:
-
Settings → Cellular (or Connections → SIM manager on Android) → Add eSIM
-
Scan the QR code or paste the activation code from your confirmation email
-
Label the line — “Taiwan data” is easier to find than “eSIM 2”
-
Set Mobile Data to the new line; leave Default Line on your home number
-
Enable Data Roaming on the Taiwan line only; leave it off on the home line
-
Send one message and load one map tile on Wi-Fi calling to confirm the setup before you fly
If something misbehaves on arrival, the profile-level fixes — a profile that will not download, an install that never registers — are catalogued in our activation troubleshooting reference.
The Taiwan-specific failure mode is almost always band-related rather than coverage-related: a regional handset variant missing one of the island’s bands shows up as “4G everywhere, slower than advertised” rather than “no signal.” Check your model against the device compatibility list if that sounds familiar, and for the underlying mechanics of what happens during install, our eSIM activation explainer covers it in plain terms.
APN settings, briefly. Tourist profiles here are digital and pre-provisioned, and all three networks push configuration to modern devices — so the access-point field is not something you should have to find. It appears only in edge cases: a locally bought SIM on an older handset, or a manual activation code. The activation troubleshooting guide covers those cases.
Three failure modes unique to Taiwan, China trips
A. The eSIM menu is locked on a contracted handset. Phones bought on installment or contract from a local carrier often keep the eSIM function disabled until the contract clears — the classic symptom is a greyed-out “Add eSIM” option on a handset that is otherwise modern and unlocked for physical SIMs. A second-hand phone originating from Taiwan, China deserves an extra check against the device compatibility reference before you rely on it for a travel profile, and a locked device needs its original carrier’s clearance first.
B. High-speed rail handovers drop the session. At 300 km/h the phone re-registers between cell sites every few seconds along parts of the corridor; most of the time it is seamless, but a video call or a large upload can drop at a handover. Nothing is broken — the profile re-attaches within seconds. Queue long uploads for a station stop, and treat the corridor’s rare dead spots as the exception they are.
C. The band gap produces 4G-only service. 5G here runs on n78 (3.5 GHz) alongside LTE bands 1/3/7/8, and some regional handset variants ship without one of them. The result is not “no signal” — it is “4G everywhere, slower than advertised,” and the fix is a model check before purchase, not a settings change on the ground.
None of the three is a coverage failure, which is the recurring theme of this island: Taiwan’s network is rarely the problem. The handset, the contract status and the plan’s fine print are where the actual failures live. For everything outside these three patterns, the troubleshooting reference and the step-by-step install guide remain the best resources.

Taiwan, China eSIM Q&A for short trips
Are Taiwan’s unlimited tourist plans really unlimited?
Unlimited tourist tiers are a standard product from all three operators, sold either at airport counters or as digital profiles. The honest caveat is the fair-use clause: confirm whether your tier is genuinely unmetered or includes a high-speed bucket with throttling after it. For a one-to-two-week trip at normal tourist usage, either kind works; heavy streamers should read the clause.
Which Taiwan carrier should you pick?
Chunghwa if your route includes mountains, the east coast or anything rural — its consistency and rural footprint lead the island. Taiwan Mobile if the trip is the three big cities and you want strong indoor performance. FarEasTone if price leads and your destinations are urban or well-trafficked. A profile that can select between networks removes the guesswork entirely.
Will your eSIM work on the Taipei MRT and the HSR?
The Taipei and Kaohsiung metros are covered through the platforms, and the HSR corridor keeps signal along nearly its whole length. You can message, navigate and stream through both — the HSR at 300 km/h included.
Which IDs work for Taiwan SIM purchase?
Real-name rules apply and the desk will register the passport number. Online tourist purchases handle verification digitally at checkout. Either way, no local address or local payment method is required, which is precisely why the tourist tiers exist.
Should your home SIM stay in the phone in Taiwan?
Yes, and you should. Keep your home SIM live for calls and SMS verification codes, point mobile data at the Taiwan eSIM line, and switch off data roaming on the home SIM so it stays silent. Most data-only tourist profiles cannot receive SMS, so banking codes will still arrive on your home number — exactly as they should.
What happens when your Taiwan eSIM runs out of data?
Top-up terms vary by where you bought: operator-direct tourist plans can usually be extended at convenience stores (which are everywhere) or through the operator’s app, while a prepaid travel plan bought abroad is typically replaced rather than topped up. If you expect to cross into heavy usage, the Taiwan, China eSIM plans page lists the current tier ladder before you commit.
How does Taiwan compare with its neighbors?
Favorably, and it is worth knowing the neighborhood context: Japan’s tourist data plans are generous but pricier per gigabyte, South Korea’s networks are superb and similarly urban-centric, and Singapore’s is a single dense market. We publish the same sourced breakdown for the destinations around it:
If your itinerary crosses to the mainland — Xiamen sits visible across the water from Kinmen — that is a separate market with separate purchases, and our China eSIM plans cover it. Note also that Hong Kong and Macao profiles do not carry to Taiwan, China or vice versa: the geography looks continuous on a map, but the telecom markets are not.
Taiwan SIM purchase ID requirements
FarEasTone’s tourist purchases specify a passport plus a second form of identification — a license, visa, or entry permit — while most other counters register on the passport alone. Carrying any second photo document costs nothing and removes the one paperwork surprise this trip can produce.
How to top up a Taiwan eSIM
Operator-direct plans are the easy case: convenience stores handle credit top-ups on every corner, and the operator apps manage bundles. Reseller-bought profiles are the exception — many are single-bucket products designed to be replaced rather than extended, which is one reason the long Chunghwa tiers are often the better value for a trip longer than ten days.
Does my Taiwan, China profile work in Hong Kong or on the mainland?
No — each is a separate telecom market, and a Taiwanese tourist plan is domestic-only. Travel profiles cover multiple regional markets only when the provider lists them, so check the country list per leg if your trip spans Hong Kong, the mainland, or beyond. The dual-profile pattern works well here: install a second profile for the next market rather than hoping one plan stretches across borders.
4G or 5G tourist tier: which should you buy?
For most visitors, the 4G tier — it is cheaper, genuinely unlimited on the handset, and 4G across Taiwan already exceeds what maps, messaging and social apps can consume. Step up to 5G only if raw speed is the point of the trip, and then read the tethering clause first, because the 5G cards trade a hotspot bucket for their headline speed. The speed table earlier in this page shows what the extra NT$ buys.
Do I need to speak Mandarin to buy at a counter?
No. The airport desks handle international arrivals all day in English, and the tourist packages are designed for exactly this transaction. City stores vary more — younger staff usually speak English, and pointing at a menu board gets you a long way. The genuinely language-free route is pre-purchase online, where the whole transaction happens in your language before you fly.
Which Taiwan carrier is best outside the cities?
Chunghwa — its consistency lead and rural footprint show up exactly where the central-mountain itineraries go. Taiwan Mobile and FarEasTone hold the towns and the main access roads well enough, but the viewpoint roads and the trails are where the extra consistency converts into actual bars. If the mountains are a headline rather than an afterthought, let the network decision make itself.
Can I use one profile for two people traveling together?
Only through tethering, and only if the plan’s clause allows it — the Chunghwa 5G tourist cards, remember, publish explicit hotspot buckets of 3–7 GB. Two separate profiles are the resilient default in Taiwan, China: purchases are cheap enough that sharing a connection saves almost nothing and doubles your points of failure.

Install a Taiwan eSIM before your plane lands
Set up your Taiwan eSIM at home, land with data already live, and put the arrivals-hall SIM queue behind you. Pick your Taiwan plan and the profile selects the strongest of Chunghwa, Taiwan Mobile or FarEasTone as you move.
Want to test it first? Try a free trial eSIM — no cost, no counter, just a working data line before you clear customs.
Before you go, the whole guide in one breath: check the phone, buy the tier that matches your day count, install it on the sofa rather than in the arrivals hall, and let the profile pick up Chunghwa when the road turns east or uphill. The island’s networks are excellent everywhere people actually stand; the only decisions that matter are the ones you made before the plane left.
Want to compare before you pay? Roami’s no-cost trial eSIM matches the carriers above across Taiwan, while WEB20 cuts 20% from your first full Roami plan. Wondering about compatibility? One minute with the checker settles it.
