The Authority for Info-communications Technology Industry of Brunei Darussalam (AITI) has become aware that users of certain mobile phone models from Xiaomi, Redmi, Poco and MI brands that are purchased either locally or abroad may not be able to connect to the national emergency numbers, i.e. 991, 993, 995 and 998. Although the affected mobile phone models can connect well with other existing local three (3) digit numbers, the call gets disconnected when any of the emergency numbers (99X) is dialed.

After conducting several investigations, testing and consultations with local telecommunications providers, AITI has concluded that this problem appears if the affected mobile phones are operating on mobile phone software MIUI Version 12.5.1 or older.  In addition to this, it is found that this is a known problem as mobile phone users from various countries also experience the same issue when dialing their respective countries' emergency numbers using the same affected mobile phone models.

In this regard, AITI would like to advise members of the public who use Xiaomi, Redmi, Poco and MI mobile phone models, in particular those who have MIUI Version 12.5.1 or older, to update their mobile phone software to the latest version if it is available. However, if there is no latest version of the mobile software, users are recommended to add the "+" sign at the end of the third digit of the 99X emergency numbers without space which should allow them to connect to the emergency numbers as shown in the table below:

All local mobile phone retailers who offer Xiaomi, Redmi, Poco and MI brands for sale, are encouraged to make this information known to customers.
