The official language of Brunei is Malay, but due to its British colonial past, English is widely spoken and understood in urban areas. A little Malay will come in handy in rural areas, as English proficiency is limited there. While all Bruneians are able to speak standard Malay, the local dialect of Malay is almost incomprehensible to other Malay speakers. Solely among the Malay-speaking states, Brunei also officially uses the Arabic script for Malay known as Jawi, although most signs are written both in Jawi and Roman letters. Nevertheless, the Roman alphabet is still the more commonly used script when writing Malay in Brunei.
The ethnic Chinese community in Brunei continues to speak a variety of Chinese dialects, including Hokkien, Teochew and several others.
The international code for Brunei is 673. The telephone numbers in Brunei consist of 7 digits with no local codes, although the first digit of the number indicates the area such as 3 for the Belait District and 2 for Bandar Seri Begawan. The prepaid Hallo Kad, available from TelBru telephone offices including one at the airport and other outlets in denominations from B$5 to B$50 can be used at any phone in the country to make local and international calls. Other phone cards are also available for use in public phones. GSM mobile phone services are available from network operator DST (http://www.dst-group.com/). They have a good range of roaming connections. 3G mobile phone services are available from B-Mobile (http://www.bmobile.com.bn/).
