For businesses operating in Taiwan, a well-chosen corporate mobile plan can significantly reduce communication costs, streamline administration, and provide essential connectivity for employees. With three major carriers—Chunghwa Telecom, Taiwan Mobile, and FarEasTone—offering tailored business solutions, selecting the right plan requires careful consideration of data needs, voice requirements, international calling, and device management. This article examines the top corporate mobile plans available in 2025, providing factual comparisons and practical guidance for small, medium, and large enterprises.

Why Choose a Corporate Mobile Plan?

Corporate mobile plans differ from consumer plans in several key ways. They typically offer centralized billing, account management portals, flexible contract terms, and discounts for multiple lines. Additionally, many plans include priority customer support, device management features, and pooled data allowances that can be shared across employees. For businesses with more than five lines, these benefits often result in lower per-line costs and simplified administration.

Top Corporate Plans by Carrier

Chunghwa Telecom (中華電信)

Chunghwa Telecom, the largest carrier in Taiwan, offers comprehensive business solutions under its “HiNet” and “Mobile Business” brands. Their corporate plans are particularly strong in coverage, especially in rural and mountainous areas, making them a reliable choice for field workers and logistics companies.

  • Business 5G Enterprise Plan (企業5G方案): Starting at NT$599 per month per line for 24-month contracts, this plan includes 24GB of pooled data, unlimited domestic calls, and free Wi-Fi at Chunghwa hotspots. Additional data is NT$30 per GB. For higher data needs, the NT$1,199 plan offers 100GB pooled data and unlimited video streaming speeds.
  • International Business Plan: Designed for companies with overseas operations, this plan includes discounted roaming rates in China, Japan, and the US. A typical plan at NT$899 per month includes 50GB domestic data, 1GB international roaming, and 200 minutes of international calls.
  • Device Management: Chunghwa offers Mobile Device Management (MDM) services for NT$50 per device per month, allowing IT administrators to remotely manage security policies and app installations.

Taiwan Mobile (台灣大哥大)

Taiwan Mobile is known for its competitive pricing and strong 5G network in urban areas. Their corporate plans emphasize flexibility and digital tools, appealing to startups and tech-focused businesses.

  • Business Freedom Plan (企業自由選方案): This plan allows businesses to mix and match data buckets and voice minutes. For example, a 10-line account can choose 5 lines with 30GB data (NT$699 each) and 5 lines with 10GB data (NT$399 each). Pooled data is available for an extra NT$100 per line.
  • 5G Business Pro Plan: At NT$999 per line per month, this plan includes 100GB pooled data, unlimited domestic calls, and a complimentary cloud PBX service for small offices. Taiwan Mobile also offers a “Bring Your Own Device” discount of NT$100 per line for companies that do not require subsidized handsets.
  • IoT Solutions: For businesses needing connectivity for devices like POS terminals or fleet trackers, Taiwan Mobile offers IoT SIM cards at NT$99 per month for 1GB data, with a minimum order of 50 SIMs.

FarEasTone (遠傳電信)

FarEasTone (FET) focuses on premium customer service and innovative features such as eSIM management and AI-powered analytics. Their plans are popular among multinational corporations and professional services firms.

  • Corporate Elite Plan (企業精英方案): Starting at NT$799 per line per month, this plan includes 50GB pooled data, unlimited domestic calls, and a dedicated account manager. The NT$1,299 tier offers 150GB data and 5GB of roaming data in Asia.
  • eSIM and Multi-Device Plans: FarEasTone provides free eSIM profiles for up to 3 devices per line, ideal for employees using both a smartphone and a tablet. The multi-device plan costs an additional NT$100 per device per month.
  • International Roaming Packages: For frequent travelers, FarEasTone offers a “Business Roaming Pass” at NT$500 per day for unlimited data in select countries, with a maximum charge of 10 days per billing cycle.

Comparing Small Business vs. Enterprise Plans

Small businesses (2-20 lines) often benefit from simplified plans with pooled data and flexible terms. For example, Taiwan Mobile’s Business Freedom Plan allows easy scaling. Medium to large enterprises (50+ lines) should consider dedicated enterprise plans from Chunghwa or FarEasTone, which offer volume discounts, dedicated support, and advanced security features such as VPN and data encryption.

Key Features to Consider

When evaluating corporate mobile plans, businesses should assess the following features:

  • Data Pooling: The ability to share data across all lines can reduce waste and lower costs. Most carriers offer pooled data as a standard feature for corporate accounts.
  • Billing and Administration: Look for online portals that allow you to view usage, adjust plans, and generate reports. Chunghwa’s “HiNet Business Portal” and FarEasTone’s “FET Business Dashboard” are examples of robust tools.
  • Device Subsidies: Some plans include discounts on smartphones. For instance, a 24-month contract with a NT$1,199 plan may offer a NT$5,000 discount on a flagship phone. However, buying phones outright and using a SIM-only plan can be cheaper in the long run. Check our best smartphones of 2025 for recommendations.
  • International Capabilities: If your business has overseas clients or employees traveling abroad, consider plans with affordable roaming rates or included international minutes.
  • Customer Support: Enterprise plans often include 24/7 priority support. FarEasTone, for example, provides a dedicated hotline for corporate clients.

How to Switch to a Corporate Plan

Switching from consumer to corporate plans is straightforward. Most carriers require a business registration certificate (統一編號) and a minimum number of lines (usually 3-5). Steps include:

  1. Contact the carrier’s business sales department via phone or website.
  2. Provide your business details and desired number of lines.
  3. Choose a plan and sign a contract (typically 12-24 months).
  4. Port existing numbers if needed (allow 2-3 working days).

Cost Comparison Example

Consider a business with 10 employees, each needing 20GB of data per month. Here’s a rough monthly cost comparison using standard corporate plans (all prices in NT$):

  • Chunghwa Business 5G Enterprise (NT$599/line): 10 x 599 = NT$5,990, with 24GB pooled data per line. Additional data at NT$30/GB if exceeded.
  • Taiwan Mobile Business Freedom (mix of 30GB and 10GB): 5 lines at NT$699 + 5 lines at NT$399 = NT$5,490. Pooling fee NT$100/line = NT$1,000, total NT$6,490.
  • FarEasTone Corporate Elite (NT$799/line): 10 x 799 = NT$7,990, with 50GB pooled data per line (more than enough).

In this scenario, Chunghwa offers the lowest base cost, but Taiwan Mobile provides more flexibility. FarEasTone is premium but includes extra features.

Additional Considerations

For businesses with employees who frequently travel, prepaid SIM cards can be a cost-effective supplement. See our prepaid SIM card buying guide for details. Also, if your business relies heavily on 5G speeds, check our 5G speed test results for real-world performance.
