Attention Post Office Account Holders! Chunghwa Post Announces: Mobile Network Transfers and Remittances May Be Disrupted on These 2 Days, Affecting 14 Counties and Cities Across Taiwan

In preparation for the 2026 Urban Resilience (Air Defense) Exercise, mobile network throttling drills will be rolled out in August across 14 counties and cities in central and northern Taiwan. These drills simulate extreme scenarios such as war, major natural disasters, or cyberattacks, where communication resources are constrained and bandwidth is limited, aiming to test the government's overall emergency response and disaster resilience. Chunghwa Post has issued a notice warning the public that using mobile networks for online services during the drills may result in slow connections or failed transactions.

The mobile network throttling drills will be conducted in two phases and regions. Phase one will take place in central Taiwan on August 10 from 2:30 PM to 3:00 PM, covering Taichung City, Miaoli County, Nantou County, Changhua County, Yunlin County, Chiayi City, and Chiayi County. Phase two will be held in northern Taiwan on August 13 during the same time slot, including Taipei City, New Taipei City, Keelung City, Taoyuan City, Hsinchu City, Hsinchu County, and Yilan County.

Will postal services be affected during the drills? Will package deliveries be delayed?

Chunghwa Post stated that all internal systems will remain fully operational during the exercise. However, customers using mobile networks may experience slower speeds or temporary service disruptions. For postal services, users accessing the official post office website via mobile networks to apply online, check registered mail status, use EZPost to generate shipping labels, or search for i-Postbox information may encounter slow page loading, temporary unavailability, or delayed status updates.

Regarding delivery personnel workflows, Chunghwa Post explained that field staff using PDAs to scan packages and return delivery confirmations may experience delayed data transmission due to reduced mobile network speeds. However, once the drill concludes and network connectivity returns to normal, the system will automatically retransmit the data, ensuring no impact on final mail tracking results.

What should users do for online transfers and financial transactions? Could repeated operations cause errors?

For savings, remittance, and financial services, Chunghwa Post advises customers to avoid using mobile networks during the drill periods. If urgent fund transfers or account operations are necessary, users should switch to fixed networks—such as Wi-Fi or wired connections—to ensure smooth transactions.

Additionally, due to reduced mobile bandwidth, push notifications and real-time messages from the Chunghwa Post Mobile App may be delayed or fail to deliver during the drills. The post office urges users to log in to the online or mobile post office after the drills to verify account activities. If network instability occurs during financial transactions, users should remain patient, avoid repeated clicks or duplicate operations, and carefully confirm final transaction outcomes while retaining transaction records.

How will insurance services be handled? Is in-person service faster?

For insurance and life insurance services, Chunghwa Post similarly recommends policyholders requiring online operations to use fixed network connections. For urgent insurance applications, customers may also consider visiting post office counters in person or submitting paper applications to avoid delays caused by mobile network throttling.
