I'm arriving in Phnom Penh and I want to make sure I have a reliable mobile network, not just to get around Cambodia but also because I work online. Which provider is best, and how is the coverage?
In Cambodia, the three main mobile operators are Smart Axiata, Metfone, and Cellcard. All of them offer affordable plans with fairly similar coverage. Personally, I've used both Smart and Cellcard, and I never had major issues. Sometimes one worked better than the other depending on the location.
Prices are very reasonable. Expect to pay around 20,000 to 40,000 KHR ($5 to $10 USD) for 50 to 100 GB of data valid for one month. If someone charges you more, be cautious. Always buy your SIM card from an official kiosk, either at the airport or at the operator's stores in town.
Mobile coverage in Cambodia is strong in urban and tourist areas such as Phnom Penh, Siem Reap (Angkor Wat), Sihanoukville, Kampot, Kep, and even on some islands like Koh Rong. Don't expect blazing speeds or consistent 4G/5G everywhere, but the mobile internet is usually good enough for browsing, working online, or making video calls. Once you leave these areas, especially in rural regions or while traveling between cities, the signal can drop or disappear.
For a reliable connection and peace of mind, I recommend Smart, which is both very popular and the largest operator in the country. Their kiosks are easy to find across Cambodia, making it simple to top up or get assistance if needed.
