What are mobile SIMs in Taiwan?

Mobile SIMs in Taiwan provide voice and 4G/5G data on the island's telecom networks, sold as postpaid monthly plans or prepaid top-up cards. The market consolidated in 2023 to three main network operators after mergers, and coverage is dense and fast, with unlimited-data plans widely available. Residents typically take a postpaid contract, while visitors and light users buy prepaid SIMs. eSIM support is growing, and number portability lets customers switch operators while keeping their number.

How the Taiwan market works

Following the 2023 consolidation, Chunghwa Telecom, Taiwan Mobile (which absorbed Taiwan Star) and FarEasTone (which merged with Asia Pacific Telecom) run the three principal networks. Plans range from budget data-only deals to premium unlimited 5G bundles, often discounted when bundled with a subsidised handset on a 24- or 30-month contract. Prepaid SIMs require ID and are popular with tourists and students. Number portability (攜碼) is straightforward and heavily used to chase promotions.

Benefits

Fast, dense coverage — Taiwan's 4G and 5G networks deliver strong speeds across cities and most rural areas.

Unlimited data — Many plans include genuinely unlimited data, popular for streaming and hotspot use.

Handset bundling — Postpaid contracts subsidise new phones, spreading the cost over the contract term.

Number portability — Keeping your number when you switch operator makes chasing better deals easy.

eSIM support — Growing eSIM availability lets you activate a plan digitally and run two numbers on one phone, handy for work and personal lines.

How to choose

Match the plan to your data appetite: heavy streamers benefit from unlimited 5G, while light users save with a capped data plan. Compare the monthly price against any handset subsidy and the total contract cost, and check the contract length and early-termination fee. Confirm 5G coverage where you live and commute, whether eSIM is supported, and any promotional discounts for porting your number or bundling home broadband.

Leading providers in Taiwan

The three network operators are Chunghwa Telecom, the largest and state-linked with the widest coverage; Taiwan Mobile, strengthened by its Taiwan Star merger; and FarEasTone, enlarged through its Asia Pacific Telecom merger. All three offer prepaid and postpaid plans, 5G, and bundling with home fibre, and several sub-brands and MVNOs resell their networks at lower price points.

What it costs

Plans in this comparison span roughly NT$53 up to NT$3,390, reflecting everything from minimal data-only or short prepaid deals to premium unlimited 5G bundles, sometimes with a handset. Mid-range unlimited 4G/5G plans commonly sit in the NT$500 to NT ,000 monthly range, while the highest figures usually include a subsidised phone spread across the contract. Short prepaid tourist packages and light data-only deals account for the lowest prices, and bundling home fibre with a mobile line can trim the effective monthly cost further.

Protections and regulation

Mobile services are regulated by the National Communications Commission (NCC), which oversees spectrum, licensing, coverage obligations and consumer protection, including number portability and contract-disclosure rules. SIM registration against ID is mandatory under identity-verification rules. The NCC also reviews operator mergers and pricing conduct to maintain competition after the market's consolidation to three networks.
