Cessation of 2G Services

Cessation of 2G Services

Since mobile communication was first introduced in Brunei Darussalam by Jabatan Telekom Brunei (JTB) in 1989 using Advanced Mobile Phone System (AMPS), it has changed the way we communicate dramatically as opposed to the alternative fixed line telephone.  Mobile phones enable users to communicate while on the move and its popularity has dominated the world.  


The revolution of mobile technology in Brunei Darussalam saw improvement throughout the years with the introduction of Global System for Mobile Communication (GSM) in 1995 by Datastream Technology Sdn Bhd (DST).  GSM is a standard developed by the European Telecommunications Standards Institute (ETSI) the protocols for second-generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets.


In 2005, 3G services were introduced with features such as video calls and mobile internet, and then upgraded to better and faster internet experience for video streaming and smart phone applications with the introduction of 4G technology in 2014.  Each successive generation of mobile communications services introduced higher speeds and enhanced user experience.


Commencing on 1 September 2019, the networks of Brunei’s four telecommunications providers: Telekom Brunei Berhad (TelBru), Datastream Technology Sdn Bhd (DST) and Progresif Cellular Sdn Bhd (Progresif), as well as Brunei International Gateway Sdn Bhd (BIG), have all been consolidated under a single entity, the Unified National Networks Sdn Bhd (UNN). In preparation for the next leap in technology, 2G services will be phased out and the 2G spectrum will be reused for the provision of more advanced mobile services, thereby enabling UNN to deliver higher standards of service quality and reliability. This aligns with UNN’s ongoing Radio Access Network (RAN) modernisation project which was announced on 1 September 2020.  This project aims to modernise the existing telecommunication infrastructure in the country to cater for higher and greater connectivity, bandwidth, and quality for the nation in preparation for forthcoming 5G deployment.

UNN will gradually cease operating 2G services, with a complete cessation by 1 June 2021. This provides an opportunity for 2G subscribers to move to higher technology services namely 3G, 4G, and eventually, 5G. As of January 2021, only a small number of 2G subscribers remain. These subscribers are advised to contact their service providers to migrate to 3G or 4G services by changing their mobile SIM-cards as soon as possible to ensure their availability of mobile services. Friends and family of 2G mobile subscribers are also encouraged to assist the less tech-savvy users in their transition to using 3G or 4G services.


UNN will work closely with all entities to ensure that subscribers are aware and informed before cessation of the 2G services. Measures will be taken to ensure any impact on service is minimal. Click HERE for the FAQs on 2G GSM Service Cessation.
