Travellers heading beyond the main towns - Mondulkiri, Ratanakiri, Preah Vihear, the islands.
Metfone is Cambodia's largest mobile network, run by the Vietnamese operator Viettel, and it has the widest rural coverage of any provider. If your trip goes beyond Phnom Penh and Siem Reap - into the northeast, the Cardamoms or the smaller islands - Metfone is the safest single choice.

Metfone is operated by Viettel, the Vietnamese military-owned telecoms group, and it has been the largest network in Cambodia for years. Its advantage is simple and it matters more than speed test results: it reaches places the others do not.
On a Phnom Penh and Angkor itinerary, any network will do. The moment your trip includes Mondulkiri, Ratanakiri, Preah Vihear, Koh Rong Sanloem or the back roads of Battambang province, coverage stops being an abstraction. Our guides carry Metfone for exactly this reason – it is the network most likely to have a bar of signal when a vehicle needs help on a provincial road.
Metfone’s national coverage comes at some cost to peak speed in the cities, where Smart has historically tested faster. For messaging, maps, ride-hailing and uploading photos, the difference is not something you will notice. For tethering a laptop and working from a cafe in Phnom Penh, it might be.
There is a Metfone counter in the arrivals hall at both Phnom Penh and Siem Reap airports, and shops in every provincial town. Bring your passport – SIM registration against a passport is a legal requirement in Cambodia, and while some small shops skip it, an unregistered SIM can be cut off without warning.
