Cellphones are plentiful in Cambodia as are available networks. The situation is chaotic, however, with many networks that don't always connect well with each other. Dropped calls, endless bleeping, and "network busy" notices are the norm. Until recently, it was hard to buy a local SIM card without proof of residency (this was to reduce the incidence of kidnappings, according to the authorities). That is now changing, although the rules remain confused and different dealers will say different things. You can buy a SIM card for about $2, and $5 top-up cards are available everywhere all over the country as scratch cards. The main providers are M Phone code 011, MobiTel code 012, Bee Line code 090, Smart Mobiel 010, Star Cell code 098, Cube code 013, and Metphone code 097. MobiTel is the most widely used. Some foreign networks are roaming-enabled in Cambodia. It not advised to use them though, unless you plan on remortgaging your house. The roaming rates are ludicrously high.

Telephone Dialing at a Glance

  • To place a call from your home country to Cambodia: Dial the international access code (011 in the U.S. and Canada, 0011 in Australia, 0170 in New Zealand, 00 in the U.K.), plus Cambodia's country code (855), the city code (23 for Phnom Penh, 63 for Siem Reap), and the six-digit phone number (for example, 011 855 23 000-000).

In Cambodia, where you find tourists you find Internet cafes. Standards vary. Phnom Penh has a few near the riverfront that would not be out of place in London. Sihanoukville wins the prize for the worst of the worst -- computers here are so riddled with viruses that they are virtually unusable. In smaller towns you might hunt harder to finder a cybervenue but there will generally be a shop or a restaurant with a couple of computers set up at the back that you can use. Rates vary between 50¢ to $1 a minute. Wi-Fi, usually free, is becoming increasingly common in hotels and restaurants. It is not always properly set up, but in Phnom Penh, Siem Reap, Battambang, Kampot, and Sihanoukville it is not hard to find a place to get connected.
