Users of mobile phones that do not support voice over long-term evolution (VoLTE) technology might need to update their phones as the nation is to shut down 3G voice service on June 30, the National Communications Commission (NCC) said yesterday.
The government terminated 3G data service in 2018 after migrating to 4G, but kept 3G voice service as the VoLTE technology was not yet mature.
More than 28 million kilowatt-hours of electricity would be conserved if the nation’s major telecoms — Chunghwa Telecom, Taiwan Mobile and Far EasTone Telecommunications — shut down the 3G network completely, the commission said.

This would in turn curb carbon emissions by approximately 142,000 tonnes, which is equivalent to the reduction possible by having 373 Daan Forest Parks (大安森林公園) in Taipei, it said.
Once the 3G voice system is shut down, people can only access data and voice services through 4G or 5G networks, the commission said, adding that users must ensure that their cellphones and SIM cards support 4G, 5G and VoLTE systems.
If the phones are too old or have yet to secure type approval from the NCC, users cannot communicate through the VoLTE network, which includes emergency hotlines 110, 119 or 112, the commission said.
Users can ascertain whether their mobile phones or SIM cards allow them to access VoLTE service by visiting their service provider’s Web site, their retail stores or calling their customer representatives, it said.
The commission also produced a commercial featuring NCC Chairman Chen Yaw-shyang (陳耀祥) to inform the public about the policy change.
“Telecoms would notify users through text messages and outbound voice calls. After receiving the message, users should visit their telecom’s retail stores for free SIM card replacement. If there are problems related to the 3G network shutdown, people can also contact their provider through its toll-free customer service number. They must also be vigilant to prevent malicious people from using their information to commit fraud,” he said.
Taiwan is to commence mass production of the Tien Kung (天弓, “Sky Bow”) III, IV and V missiles by the second quarter of this year if the legislature approves the government’s NT$1.25 trillion (US$39.78 billion) special defense budget, an official said yesterday. Commenting on condition of anonymity, a defense official with knowledge of the matter said that the advanced systems are expected to provide crucial capabilities against ballistic and cruise missiles for the proposed “T-Dome,” an advanced, multi-layered air defense network. The Tien Kung III is an air defense missile with a maximum interception altitude of 35km. The Tien Kung IV and V
The disruption of 941 flights in and out of Taiwan due to China’s large-scale military exercises was no accident, but rather the result of a “quasi-blockade” used to simulate creating the air and sea routes needed for an amphibious landing, a military expert said. The disruptions occurred on Tuesday and lasted about 10 hours as China conducted live-fire drills in the Taiwan Strait. The Civil Aviation Administration (CAA) said the exercises affected 857 international flights and 84 domestic flights, affecting more than 100,000 travelers. Su Tzu-yun (蘇紫雲), a research fellow at the government-sponsored Institute for National Defense and Security Research, said the air
Taiwan lacks effective and cost-efficient armaments to intercept rockets, making the planned “T-Dome” interception system necessary, two experts said on Tuesday. The concerns were raised after China’s military fired two waves of rockets during live-fire drills around Taiwan on Tuesday, part of two-day exercises code-named “Justice Mission 2025.” The first wave involved 17 rockets launched at 9am from Pingtan in China’s Fujian Province, according to Lieutenant General Hsieh Jih-sheng (謝日升) of the Office of the Deputy Chief of the General Staff for Intelligence at the Ministry of National Defense. Those rockets landed 70 nautical miles (129.6km) northeast of Keelung without flying over Taiwan,
A strong continental cold air mass is to bring pollutants to Taiwan from tomorrow, the Ministry of Environment said today, as it issued an “orange” air quality alert for most of the country. All of Taiwan except for Hualien and Taitung counties is to be under an “orange” air quality alert tomorrow, indicating air quality that is unhealthy for sensitive groups. In China, areas from Shandong to Shanghai have been enveloped in haze since Saturday, the ministry said in a news release. Yesterday, hourly concentrations of PM2.5 in these areas ranged from 65 to 160 micrograms per cubic meter (mg/m³), and pollutants were
