The practical basics for a smooth trip: one emergency number, how to pay, staying connected, staying healthy, when to come, and the customs and holidays worth knowing before you land.
112 is Indonesia's single national emergency number, free to call from any phone, even one without credit or a SIM. It connects to police, fire and ambulance services, which also keep their own numbers (110 police, 113 fire, 119 ambulance).
The Bali Governor's circular of March 2025 sets out what is expected of foreign visitors: respect temples and ceremonies, dress modestly at sacred sites, pay the tourist levy, use licensed guides and accommodation, and avoid single-use plastics, inner temple areas and any unlicensed work.
Travel insurance with medical evacuation cover is strongly advised, especially for events on Lombok, in Riau or on Nias, where the nearest major hospital may be hours away. The Ministry of Tourism runs a national tourism safety programme with local governments and rescue agencies.
