A telecoms regulator in Taiwan has warned that an aggressive price war among mobile operators could reduce their incentive to invest in new services and network upgrades, including the rollout and expansion of 5G.
The National Communications Commission (NCC) issued the caution after Chunghwa Telecom — Taiwan’s largest telecom operator — rolled out low-cost unlimited 4G data and voice plans. Chunghwa serves more than a third of the country’s mobile subscribers and dominates the fixed broadband market with roughly 80% share, making its pricing moves particularly influential across the industry.
While consumers typically welcome lower prices, the NCC warned that sustained, deep price competition could undermine long-term network quality and innovation. In the short term, cheaper unlimited plans may boost subscriber numbers and consumer satisfaction, but if margins shrink too far, operators may struggle to justify the capital and operating expenditures required for modern networks and new services.
“If telecoms simply want to boost their market shares and revenue by luring subscribers from competitors, rather than with innovative business models, it would not be positive for the development of 5G in the nation,” said NCC spokesperson Wong Po-Tsung (翁柏宗).
“What they are doing does not help to make the pie bigger. They are not benefiting from innovative business models that could sustain them through the maintenance and operation of 4G services, the auctioning of the 5G service spectrum and finally commercial operation of 5G.”
The regulator’s remarks emphasize several industry concerns: the need to preserve healthy operator revenues to fund spectrum purchases, build and maintain dense 5G networks, and support new services that rely on 5G capabilities, such as fixed wireless access, ultra-reliable low-latency communications, and massive IoT deployments. If providers are forced to compete solely on price, there may be less appetite for innovative offerings, network densification, and long-term investments that benefit consumers and businesses alike.
After Chunghwa’s announcement, competitors including Taiwan Mobile, Far EasTone Telecommunications and Asia Pacific Telecom quickly introduced similar low-cost unlimited offerings, intensifying price competition across the market. Such responses are common in markets with a dominant player initiating aggressive pricing, as rivals move to protect their own customer bases.
Regulators face a balancing act: encouraging affordable services and healthy competition while ensuring operators maintain sufficient revenue to invest in next-generation infrastructure. Policymakers and industry stakeholders may need to consider regulatory tools and incentives that promote both consumer-friendly pricing and sustainable investment — for example, ensuring fair spectrum allocation processes, fostering new revenue-generating services, and supporting innovative business models that diversify operator income beyond basic connectivity.
For consumers, lower prices can deliver immediate benefits, but the long-term impacts on service quality, network coverage and the pace of 5G deployment deserve attention. Industry observers note that a market focused primarily on price risks slowing the broader digital transformation that advanced networks enable, potentially affecting enterprise services, smart city initiatives and digital inclusion efforts.
Ultimately, the NCC’s warning highlights the tension between short-term consumer gains and long-term national digital infrastructure goals. How operators, regulators and policymakers respond will shape Taiwan’s 5G landscape and the availability of next-generation services for businesses and citizens.
