Electricity & Water
Indonesia runs 127V AC/50Hz but is in the process of converting to a 230V AC/50Hz. This conversion is complete in principal cities. Indonesia uses a type C,F, and G plug so North Americans travelling with electronics will need adapters.

It is not advisable to drink tap water in Indonesia, but bottled mineral water is safe and available everywhere. Ice in drinks is generally OK in good standard hotels and restaurants but it is best to avoid it on street stalls or in country areas.

Clothing
With temperatures ranging between 20-35�C, light, casual clothes are the most practical. Natural fibres like cotton or linen are the most comfortable in Indonesia's often humid conditions. Casual clothes are acceptable in most places and a lightweight suit and tie are usual for business or formal meetings. Light cotton dresses are generally acceptable in most situations. Batik is popular for both men's shirts and women's dresses.

Communications
Telephone
IDD is available to main cities. Country code: 62 (followed by 431 for Manado, 22 for Bandung, 21 for Jakarta, 61 for Medan and 31 for Surabaya). Outgoing international code: 00. Many hotel lobbies have public phones which take credit cards and phone cards. State-operated phone booths (WARTEL), which work on a pay-as-you-leave basis, can be found throughout the country. For emergencies, dial 110 (police) or 118 (ambulance for traffic accidents) or 119 (ambulance for general health) or 113 (fire department).
