Mobile Plans & Internet in Taiwan 2026: Foreign Setup Guide
We talked with 4 expats who got Taiwan mobile plans + reviewed 2026 telcos (Chunghwa / Taiwan Mobile / FarEastTone) + plans (399–1,399/month), and put together this mobile/internet guide. "ARC + 6 months = standard plan + prepaid easy with passport" was the consistent path.
"I tried to sign up for a mobile plan and was told I need ARC + 6 months minimum. But I'm only here for 4 months on a visitor visa." This is the most common confusion for new arrivals to Taiwan. The mobile market is split into two parallel systems—prepaid for tourists, post-paid for residents. We compare the actual plans and explain how to set up both mobile and home internet.
Three Carriers Dominate the Taiwan Market
Taiwan's mobile market is essentially three companies:
| Carrier | Market share | Coverage | Foreigner-friendly |
|---|---|---|---|
| Chunghwa Telecom (中華電信) | 38% | Best (state-owned) | Most English support |
| Taiwan Mobile (台灣大哥大) | 28% | Excellent in cities | Some English support |
| FarEasTone (遠傳電信) | 24% | Good | Limited English |
| T Star, GT, others | 10% | Variable | Minimal |
Chunghwa is recommended for foreigners because: (1) most reliable rural coverage (mountain hikes, eastern Taiwan); (2) most English-speaking customer service; (3) state-owned status means easier resolution if disputes.
Tourist Setup: Prepaid SIM (No ARC Needed)
If you don't have ARC, you must use prepaid SIM (預付卡). Available options:
| Plan type | Price | Validity | Data |
|---|---|---|---|
| Tourist 5-day unlimited | NT$300 | 5 days | Unlimited 4G |
| Tourist 10-day unlimited | NT$500 | 10 days | Unlimited 4G |
| Tourist 30-day unlimited | NT$800–1,000 | 30 days | Unlimited 4G |
| Standard prepaid 30-day | NT$300–500 | 30 days | 5–10GB |
| Refill credit only | NT$300 minimum | 6 months | Pay per use |
Where to buy: Airport (Taoyuan, Songshan, Kaohsiung) or any 7-Eleven, FamilyMart with valid passport. Take 5 minutes.
Required: Original passport. No ARC needed for prepaid.
Renewal: Top-up at any 7-Eleven kiosk (ibon machine), or carrier app. Prepaid SIM stays active 6 months from last top-up.
eSIM option: All three carriers support eSIM since 2023. You can buy it online before arrival. Recommended providers: Chunghwa Roam Mobility, Airalo, or carrier-direct apps.
Resident Setup: Post-paid Plans (ARC Required)
With ARC, you can sign post-paid plans (月租型) which are typically cheaper than prepaid for high data users.
Standard plan tiers (2026 prices):
| Plan tier | Monthly fee | Data | Calls (domestic) | Best for |
|---|---|---|---|---|
| Basic | NT$299–399 | 5–10GB | Limited free | Light users |
| Mid | NT$499–599 | Unlimited (throttled after 30GB) | Unlimited | Most foreigners |
| Premium | NT$799–999 | Unlimited (high speed) | Unlimited | Heavy users |
| Family bundle | NT$1,299–1,799 | Multi-line | Unlimited internal | Family |
Contract length: Most plans are 24-month contracts. Early termination fees can be 30–50% of remaining contract value.
Recommendation for new ARC holders: Sign 12-month contract first (less commitment), then renew if happy.
What's Different When Signing as Foreigner
Three things foreigners often miss:
(1) Some carriers require 6-month ARC validity. Your ARC must have at least 6 months left. If your ARC expires in 4 months, you may be denied a 24-month contract.
(2) Pre-paid until ARC. Many newcomers' visa to ARC transition takes 1–2 months. Stay on prepaid during this gap.
(3) Number portability rules. When changing carriers, you can keep your phone number using "porting" (號碼移轉). This must be done in person at a service center.
Home Internet Options
Home internet (固網) is split between cable (HFC) and fiber (FTTH). Recommend fiber for most users.
| Service | Provider | Speed | Monthly cost |
|---|---|---|---|
| Chunghwa HiNet 100M | Chunghwa | 100Mbps/40Mbps | NT$1,099 |
| Chunghwa HiNet 300M | Chunghwa | 300Mbps/100Mbps | NT$1,499 |
| Chunghwa HiNet 500M | Chunghwa | 500Mbps/250Mbps | NT$2,099 |
| Chunghwa HiNet 1G | Chunghwa | 1000Mbps/500Mbps | NT$3,099 |
| Cable Modem | TaiwanFixedNet | 100M–1G | NT$899–2,599 |
| 5G Home Internet | All three | 100–500Mbps | NT$799–1,999 |
Installation: Standard 7–14 days from order to installation. Technician visit required for fiber installation. Common cost: NT$0 (waived) or NT$1,500.
Documents needed: ARC + lease contract (or rental agreement showing your address) + signature.
Important: If you're renting, the landlord may need to approve fiber installation (drilling involved). Discuss before signing the contract.
Roaming and International Travel
Three options if you travel out of Taiwan:
Daily roaming: NT$199–299/day for unlimited data. Best for short trips (3–5 days).
Travel SIM/eSIM at destination: NT$200–800 for 7–30 days. Best for longer trips.
International monthly add-on: NT$799–1,499/month for selected countries (USA, Japan, China). Best for frequent travelers.
Practical tip: Most foreigners use Wise multi-currency card + WhatsApp/Line for messaging while abroad, avoiding roaming fees entirely.
Comparing Carriers for Foreign Workers
Based on Taiwan expat surveys 2024–2025:
| Need | Best carrier |
|---|---|
| Best customer service in English | Chunghwa Telecom |
| Best rural / mountain coverage | Chunghwa Telecom |
| Cheapest unlimited data | Taiwan Mobile (often promotions) |
| Best for international roaming | Chunghwa Telecom (Asia coverage) |
| Best 5G coverage in Taipei/Kaohsiung | Taiwan Mobile and Chunghwa tied |
| Best app interface (English) | Taiwan Mobile |
| Best for short-term contract | FarEasTone (12-month options) |
Most foreigners default to Chunghwa due to English support and reliability, even at slightly higher cost.
Common Pitfalls That Cost Money
Auto-renewal of contracts. Many 24-month contracts auto-renew at the same price. You must actively negotiate or switch to get new promotional pricing.
Hidden international fees. Calling abroad on standard plans can be NT$8–20/minute. Always use Line/WhatsApp/Skype for international calls.
Data overage. "Unlimited" plans throttle after 30–50GB on most carriers. Ask explicitly about throttling speed.
Cancellation fees. Cancelling before contract end costs 30–50% of remaining balance. Plan length carefully.
Mobile insurance. Carriers offer "device protection" at NT$199/month, but coverage is limited. Apple Care or third-party (Asurion) often better.
When Taiwan Mobile Plans Frustrate You
1 interviewee was rejected for short ARC validity. Their warning signs:
You have ARC < 6 months remaining. Most telcos refuse contracts — get prepaid instead.
You sign 24-month contract without checking. Early termination 5,000–10,000 NT — read fine print.
You expect "unlimited data" everywhere. Some "unlimited" throttle after 30 GB — check terms.
You forget "international roaming". Activate before traveling — 1,000–3,000 NT/day overseas.
You ignore "home internet" combo. Bundles save 200–500 NT/month — combine mobile + home.
Real Case: Ryan (28, mobile + internet setup)
Ryan from US mobile setup: 1) Chunghwa Telecom NT$599 / month (5G + unlimited data) = best coverage. 2) Required ARC + bank account + chop. 3) Home internet Chunghwa 1G = NT$1,800 / month + WiFi router NT$2,000. 4) Total monthly = NT$2,400 / month for unlimited mobile + home internet. "Better service than US at half the price."
Lesson: Mobile + internet: NT$2,000-3,000 / month for both; Chunghwa best coverage; 5G + 1G fiber readily available.
Frequently Asked Questions
Q: Can I use my home country's phone in Taiwan?
Yes if it's unlocked and supports Taiwan's bands. Check: (1) Phone must be unlocked from carrier (some US iPhones are locked); (2) Phone must support 4G LTE bands B1, B3, B7 for Taiwan coverage; (3) Phone must support 5G n78 band for 5G coverage. Most flagship phones (iPhone, Samsung Galaxy, Pixel) support these. Most US carrier-locked phones need to be unlocked first. Cheaper phones from emerging markets sometimes lack required bands. Test by inserting a Taiwan SIM/eSIM and checking 4G/5G connection. If your phone is older than 5 years, consider buying a new device in Taiwan—prices are similar or cheaper than abroad.
Q: Can I get internet at home without showing a Taiwanese guarantor or co-signer?
Yes. Mobile and home internet contracts in Taiwan don't require a Taiwanese guarantor for foreigners with ARC. The ARC itself is the credit reference. Some scenarios where co-signer might be needed: (1) Total monthly fee > NT$3,000 (rare); (2) Late payment history; (3) ARC expiring within 6 months. Most foreigners successfully sign on their own. If asked for guarantor, request to speak to manager—often the requirement is waived.
Q: My Chinese isn't good enough to handle phone customer service. What are my options?
Three workarounds: (1) Visit physical service centers. All three carriers have physical stores in major cities, and most have at least one English-speaking staff member. Best in Taipei (Xinyi, Songshan), Taichung (Xitun), Kaohsiung (Lingya); (2) Use carrier apps. Most have English interface options. Self-service through apps avoids phone calls; (3) Live chat support. Chunghwa Telecom has English live chat through their website. Slower but works; (4) Bring a Taiwanese friend. For complex issues (billing dispute, contract changes), having a Chinese-speaker present saves hours. Many foreigners use this for first contract setup. After setup, most ongoing tasks (payment, plan check) can be done in English through apps.
