[Maintaining the Principle of Fair Internet Usage]

To maintain the quality of internet connectivity and the Fair Usage Policy (FUP), telecom companies worldwide may impose data limits on customers who use large amounts of internet traffic in a short period, which may lead to internet access failure or slower speeds. To ensure you can maintain a stable connection, please try to avoid activities that consume a large amount of data, such as prolonged video streaming/downloading, software updates, sharing the internet (hotspot) with others, or other high-data usage activities.
