Taiwan's 5G market has matured significantly since its 2020 launch. As of 2025, all major carriers—Chunghwa Telecom, Taiwan Mobile, FarEasTone, T Star (now merged with Taiwan Mobile), and GT (now part of Asia Pacific Telecom, recently acquired by FarEasTone)—offer robust 5G networks covering over 95% of the population. Choosing the right plan depends on your data usage, budget, and desired extras like streaming subscriptions or roaming benefits. This guide breaks down the best 5G plans in Taiwan for 2025, with concrete prices, data caps, and key features.

Market Overview: 5G in Taiwan 2025

Taiwan's 5G rollout has been aggressive. According to the National Communications Commission (NCC), 5G subscriptions exceeded 12 million by the end of 2024, representing roughly 50% of mobile users. The three main players—Chunghwa Telecom, Taiwan Mobile (which merged with T Star in late 2023), and FarEasTone (which acquired Asia Pacific Telecom in 2024)—now offer a range of plans from budget-friendly light data to unlimited high-speed options. Prices have remained competitive, with entry-level 5G plans starting around NT$399 per month and premium unlimited plans reaching NT$1,399 or more.

Chunghwa Telecom 5G Plans

Chunghwa Telecom, the incumbent, boasts the widest 5G coverage, especially in rural areas. Their 2025 lineup includes:

  • Chunghwa 5G 599: 24GB at full speed, then unlimited at 5Mbps. Price: NT$599/month. Includes free Hami Video basic and 30-minute free calls.
  • Chunghwa 5G 999: 60GB at full speed, then unlimited at 10Mbps. Price: NT$999/month. Includes Hami Video premium, 60-minute free calls, and 5GB of domestic roaming data.

Chunghwa's plans are ideal for heavy users who need consistent speeds and extensive coverage. The unlimited 1399 plan is among the fastest in Taiwan, often achieving 1Gbps down in dense urban areas.

Taiwan Mobile 5G Plans (including T Star)

Taiwan Mobile (TWM) completed its merger with T Star in late 2023, integrating T Star's 5G spectrum. Their 2025 plans offer competitive pricing and generous streaming perks.

  • TWM 5G 399: 12GB at full speed, then unlimited at 5Mbps. Price: NT$399/month. Includes free myVideo basic and 20-minute free calls.

  • TWM 5G 799: 60GB at full speed, then unlimited at 10Mbps. Price: NT$799/month. Includes myVideo premium, 60-minute free calls, and 5GB domestic roaming.
  • TWM 5G 1399: Unlimited full-speed data. Price: NT$1,399/month. Includes myVideo premium, 90-minute free calls, 10GB domestic roaming, and Disney+ subscription (6 months).

FarEasTone 5G Plans

FarEasTone (FET) merged with Asia Pacific Telecom (GT) in 2024, expanding its 5G coverage. Their 2025 plans emphasize streaming and international roaming.

  • FET 5G 399: 12GB at full speed, then unlimited at 5Mbps. Price: NT$399/month. Includes free friDay Video basic and 20-minute free calls.

Budget 5G Plans: Light Users

For light users who primarily use Wi-Fi, budget 5G plans under NT$400 are available. Chunghwa, TWM, and FET all offer 12GB or 24GB plans at NT$399–599. Additionally, some MVNOs like 1Mobile Taiwan provide competitive prepaid 5G options.

Prepaid 5G Options

Prepaid 5G is ideal for short-term visitors or those who want no contract. Major carriers offer prepaid 5G data packs:

  • Chunghwa Prepaid 5G: 30-day pass with 5GB at full speed for NT$300; 10GB for NT$500; 20GB for NT$800.
  • Taiwan Mobile Prepaid 5G: 30-day pass with 5GB for NT$250; 10GB for NT$450; 20GB for NT$750.
  • FarEasTone Prepaid 5G: 30-day pass with 5GB for NT$280; 10GB for NT$480; 20GB for NT$780.

Prepaid plans do not include streaming perks but offer flexibility. They can be purchased at carrier stores, convenience stores (7-Eleven, FamilyMart), and online retailers like 1Mobile Taiwan.

How to Choose the Right 5G Plan in 2025

Selecting the best 5G plan depends on your usage pattern:

  • Heavy users (30GB+ per month): Opt for an unlimited plan (NT$1,399) from any carrier. Chunghwa's 1399 offers the best coverage; TWM's 1399 includes Disney+.
  • Moderate users (10–30GB per month): Plans like TWM 799 or FET 999 (60GB) are cost-effective. If you use exactly 24GB, Chunghwa 599 or TWM 599 work well.
  • Light users (under 10GB per month): Budget plans at NT$399–599 with 12–24GB are sufficient. Prepaid may be cheaper if you use under 5GB.
  • Streaming fans: Choose a plan that includes your preferred service: Hami Video (Chunghwa), myVideo (TWM), or friDay Video (FET). TWM's 1399 includes Disney+ for six months.
  • Frequent travelers: Look for plans with domestic roaming data (e.g., Chunghwa 999 includes 5GB). For international roaming, consider add-ons.

Network Performance Comparison

Speed tests from Ookla (2024 Q4) show:

  • Chunghwa Telecom: Median download speed 412 Mbps, upload 52 Mbps. Best in rural areas.
  • Taiwan Mobile: Median download speed 389 Mbps, upload 48 Mbps. Strong in urban centers.
  • FarEasTone: Median download speed 375 Mbps, upload 45 Mbps. Good overall, with improvements post-merger with GT.

All three carriers have similar latency (~15ms). Chunghwa leads in coverage, while TWM and FET offer competitive speeds in cities.

Contract Considerations

Most 5G plans require a 12- or 24-month contract. Early termination fees typically range from NT$2,000 to NT$5,000, decreasing over time. Some plans offer device subsidies (e.g., NT$5,000 off a new phone) with longer contracts. If you prefer no contract, prepaid or 1Mobile Taiwan's MVNO plans are worth exploring.
