Choosing the best family mobile plan in Taiwan can save a household thousands of NT dollars each month while ensuring everyone gets the data and call minutes they need. With three major carriers—Chunghwa Telecom, Taiwan Mobile, and FarEasTone—each offering bundled family discounts, add-on lines, and shared data pools, it pays to compare. This guide breaks down the top family plans available in 2025, including pricing, data allowances, and hidden perks like streaming subscriptions and free Wi-Fi.
Whether you are a family of two or five, understanding how family plans work in Taiwan will help you avoid overpaying for individual lines. We also cover prepaid options for children or short-term visitors, and how to mix postpaid and prepaid within one household.
How Family Mobile Plans Work in Taiwan
Family plans in Taiwan are typically postpaid accounts where one primary subscriber (the account holder) adds secondary lines under the same bill. Discounts apply to the monthly fees of the additional lines, often ranging from NT$100 to NT$200 off per line. Most carriers require a 12- or 24-month contract, though some offer no-contract options at a higher monthly rate.
Key factors to compare:
- Data pooling: Some plans share a single data bucket across all lines; others give each line its own allowance.
- Discount tiers: The more lines you add, the larger the discount per line. Maximum discounts usually apply at 4-6 lines.
- Speed caps: Cheaper family plans may throttle data after a certain amount (e.g., 21 Mbps vs. full-speed 5G).
- Extra perks: Free streaming services (KKBOX, CATCHPLAY+, friDay影音), Wi-Fi hotspot access, or shopping vouchers.
All three major carriers also offer corporate or employer-sponsored plans, but for families, the consumer plans below are the most straightforward.
Chunghwa Telecom Family Plans
Chunghwa Telecom, the state-owned incumbent, has the widest 4G/5G coverage and the most family plan options. Their flagship family plan is the “大4G 家族方案” (Big 4G Family Plan), which now includes 5G access on qualifying tiers.
Chunghwa 5G Family Plan (精選5G 家族方案)
This plan is available for 2 to 6 lines. The primary line pays the standard rate for a 5G plan (e.g., NT$599 for 24GB, NT$999 for 60GB, or NT$1,399 for unlimited), and each additional line receives a monthly discount of NT$100–NT$200 depending on the plan tier.
- Example 4-line setup: Primary on NT$999 (60GB 5G), three additional lines each on NT$699 (36GB 5G). After discounts, each additional line costs NT$599. Total: NT$999 + 3×NT$599 = NT$2,796/month.
- Data: Each line has its own data allowance; no pooling. All lines get unlimited 5G speed until the cap, then 12Mbps throttled.
- Perks: Free KKBOX Prime (music + video) for the primary line; Hami Video pass; free Wi-Fi at Chunghwa hotspots.
Chunghwa 4G Family Plan (大4G 家族方案)
For families that don't need 5G, the 4G family plan offers lower monthly fees. The primary line can choose from NT$399 (6GB), NT$599 (24GB), or NT$799 (unlimited 4G with 21Mbps cap). Additional lines get NT$100 off per line for the first two lines, and NT$200 off for the third and fourth.
- Example 4-line setup: Primary on NT$799 (unlimited 4G), three additional lines on NT$599 (24GB each). After discounts: NT$799 + NT$499 + NT$499 + NT$499 = NT$2,296/month.
- Note: Unlimited 4G on the primary line is actually “unlimited” but subject to deprioritization after 100GB.
Chunghwa also offers a “寵愛家人方案” (Cherish Family Plan) for seniors (60+), which gives an extra NT$100 discount per line. This can be combined with the family plan for multi-generational households.
Taiwan Mobile Family Plans
Taiwan Mobile (台哥大) is known for aggressive discounts on additional lines and generous data pooling options. Their family plan is called “好速家族” (Good Speed Family) and comes in 4G and 5G variants.
Taiwan Mobile 5G Family Plan (5G 好速家族)
This plan allows up to 5 lines to share a single data pool. The primary line chooses a base plan (NT$599/24GB, NT$799/60GB, NT$999/100GB, or NT$1,399/unlimited), and each additional line pays NT$199/month for the same plan (but with a smaller individual data allowance if the pool is exceeded). However, the key feature is that all lines share the primary's data allowance.
- Example 4-line setup: Primary on NT$999 (100GB pool). Additional lines: 3 × NT$199 = NT$597. Total: NT$1,596/month for 100GB shared among 4 lines.
- Data pooling: All lines consume from the same bucket. Once the pool is exhausted, speeds drop to 5Mbps for all lines.
- Perks: Free myVideo (streaming) for the primary line, plus 6 months of Disney+ for new subscribers.
Taiwan Mobile also offers a “4G 好速家族” with similar pooling but lower base prices (NT$399/6GB, NT$599/24GB, NT$799/unlimited 21Mbps). Additional lines cost NT$149/month each.
Taiwan Mobile Prepaid Family Option
For families who want to avoid contracts, Taiwan Mobile has a prepaid family plan where you can buy data packs (e.g., 30GB for NT$300) and share them among up to 5 prepaid lines. This is ideal for children or short-term visitors. See our best prepaid data plans guide for details.
FarEasTone Family Plans
FarEasTone (遠傳) offers the “遠傳大雙網家族” (FarEasTone Dual Net Family) plan, which focuses on combining mobile and fixed-line broadband discounts. They also have a pure mobile family plan called “遠傳家族省” (FarEasTone Family Save).
FarEasTone 5G Family Save (5G 家族省)
This plan offers a discount of NT$100 per additional line for the first two lines, and NT$200 for the third and fourth. The primary line can choose from NT$599 (24GB), NT$799 (60GB), NT$999 (100GB), or NT$1,399 (unlimited). Additional lines can be on a different tier, but the discount applies to the base fee of each additional line.
- Example 4-line setup: Primary on NT$999 (100GB), additional lines on NT$599 (24GB each). After discounts: NT$999 + NT$499 + NT$499 + NT$399 = NT$2,396/month.
- Data: Each line has its own allowance; no pooling.
- Perks: Free friDay影音 (movies) for the primary line; free Wi-Fi at FarEasTone hotspots; shopping vouchers for ETMall.
FarEasTone Dual Net Family
If your household also uses FarEasTone fixed-line broadband (光纖), you can bundle mobile lines with home internet for extra savings. For example, a 300Mbps fiber plan at NT$699/month plus two mobile lines at NT$599 each can be combined for a total of NT$1,499 (saving NT$300). This is a great option for families that need both home and mobile connectivity.
FarEasTone also offers a “4G 家族省” with similar discounts but lower data caps (e.g., NT$399/6GB, NT$599/24GB, NT$799/unlimited 21Mbps).
Comparison Table (4-Line Family Plans, Mid-Tier)
Below is a rough comparison of three typical 4-line family plans with moderate data needs (e.g., 24-36GB per line or shared pool). Prices are approximate and include discounts.
| Carrier | Plan Name | Total Monthly Cost | Total Data | Speed After Cap |
|---|---|---|---|---|
| Chunghwa | 5G 家族方案 (NT$999 + 3×NT$699) | NT$2,796 | 60GB (primary) + 3×36GB = 168GB | 12Mbps |
| Taiwan Mobile | 5G 好速家族 (NT$999 + 3×NT$199) | NT$1,596 | 100GB shared | 5Mbps |
| FarEasTone | 5G 家族省 (NT$999 + 3×NT$599) | NT$2,396 | 100GB (primary) + 3×24GB = 172GB | 12Mbps |
Note: Taiwan Mobile's shared plan is cheapest but offers the least total data and a slower throttle speed. Chunghwa and FarEasTone give each line its own data, which may be better for heavy users. Always check current promotions, as carriers frequently offer limited-time discounts.
Tips for Choosing the Best Family Plan
- Assess data usage per person: If one person streams video heavily, a shared pool may be depleted quickly. Individual allowances prevent one user from hogging data.
- Consider 5G vs. 4G: 5G plans are pricier but offer faster speeds. For most families, a good 4G plan with 21Mbps cap is sufficient. Read our 5G plan comparison for more details.
- Check coverage: Chunghwa has the best rural coverage; Taiwan Mobile and FarEasTone are strong in cities. Use coverage maps before committing.
- Look for extra perks: Streaming subscriptions (KKBOX, Disney+, CATCHPLAY+) can save you NT$200-400 per month if you would pay for them separately.
- Mix prepaid and postpaid: For children or elderly family members who use little data, a prepaid plan may be cheaper than adding a postpaid line. See our student mobile plans guide for low-cost options.
- Negotiate at stores: Often, carrier store representatives can offer additional discounts or waive activation fees if you sign a 24-month contract. It never hurts to ask.
Frequently Asked Questions
Can I add a prepaid line to a family plan?
No, family plan discounts only apply to postpaid lines under the same account. However, you can have both postpaid and prepaid lines under the same household; they just won't share discounts.
What happens if we exceed the data cap?
On individual allowance plans, each line is throttled independently. On shared plans, all lines are throttled once the pool is exhausted. Speeds drop to 5-12Mbps depending on the plan. You can usually buy top-up data (e.g., 1GB for NT$50) to restore full speed.
Can I change the primary line later?
Yes, but it may involve a contract amendment. Contact your carrier's customer service; some charge a fee (NT$200-300) for changing the account holder.
Are there family plans for small businesses?
Yes, all three carriers offer corporate plans with even larger discounts for 5+ lines. See our small business mobile solutions guide for details.
Final Recommendations
For most families, Taiwan Mobile's 5G 好速家族 offers the best value if you can stay within the shared data pool. If you prefer individual data allowances, Chunghwa's 5G 家族方案 is a solid choice with excellent coverage. FarEasTone's Dual Net Family is ideal if you also need home broadband.
Before signing, check current promotions on the carrier websites or visit a physical store. Prices and discounts change frequently, especially around holidays like Chinese New Year or Back-to-School season.
