ATMs -- There are ATMs all around Sihanoukville. They take all international cards. The best one to use is the Canadia Bank, since they have the lowest charges.
Banks & Currency Exchange -- Canadia Bank (197 Ekareach St.; tel. 034/933-490; open Mon-Fri 8am-3pm, Sat 8-11:30am), UCB (195 Ekareach St.; tel. 034/933-833; open Mon-Fri 8am-3pm), ANZ (215 Ekareach St.; open Mon-Fri 8:30am-4pm), and ACLEDA Bank (135 Ekareach St.; tel. 034/320-232; open Mon-Fri 7:30am-4pm, Sat 7:30am-noon) are all situated downtown. They all cash traveler's checks, exchange major foreign currencies, and issue advances on Visa and MasterCard.
Business Hours -- Business hours are generally between 7am and 7pm from Monday to Friday. Nightlife in parts of Sihanoukville runs 24 hours.
Doctors & Hospitals -- Medical care in Sihanoukville is woeful. The CT Clinic (47 Boray Kamakor; tel. 034/934-222; open 24 hr.) should be your first stop if in need. Apart from that, you should head up to Phnom Penh and on to Thailand for anything complex or serious.
Internet Access -- There are Internet cafes scattered around all areas where there are tourists. Many of the machines are so badly maintained and so riddled with viruses that they do not function. The excellent Beach Club Resort has Wi-Fi in the restaurant by the pool.
Pharmacies -- The CT Clinic has a pharmacy that you can trust. Other more dubious ones can be found downtown.
Post Office -- The main post office (Ekareach St. at the intersection of Mittapheap and Kampuchea-Soviet St.) is open Monday to Friday 6am to 5pm and Saturday 8am to noon.
Telephone -- Internet cafes are equipped for long-distance calls. There are also scores of shops selling mobile SIM cards and phones all over the center of town. A new SIM card costs as little as $2 and is your best option if you want to make local calls.
Tourism Information -- The best source of information is from guesthouses and hotels. They will book trips to the islands and onward travel.
