📱 Mobile Internet Disruption Drill
Taiwan will conduct its first mobile internet disruption drill in northern and central Taiwan. During the 30-minute exercise, 4G and 5G data speeds will be deliberately slowed, but phone calls, SMS, public alerts, Wi-Fi and fixed-line internet should continue working normally.
Central Taiwan: August 10, 2:30–3:00 p.m.
Northern Taiwan: August 13, 2:30–3:00 p.m.
Residents are advised to use Wi-Fi, voice calls or SMS and avoid mobile-data-heavy activities such as video calls, large file uploads and online trading during the drill.
For the first time, the nationwide Urban Resilience Exercises and air raid drills on Aug. 10 and 13 will include a simulation of a major slowdown in mobile internet speeds in 14 cities and counties across northern and central Taiwan.
