Network coverage in Cambodia
Local carriersCambodia has 1 eSIM-accessible carrier for visitors: Metfone on 4G LTE. Metfone is Cambodia's largest mobile operator by infrastructure, partially owned by Viettel. Cellcard and Smart (Axiata) cover similar urban territory but do not offer international e-sim provisioning in 2026. Metfone reaches Phnom Penh, Siem Reap, Sihanoukville, Kampot, and the main national highways. Your e-sim auto-registers at PNH or REP on arrival.
Coverage analysisMetfone 4G covers Phnom Penh (all districts including Riverside, BKK1, and Toul Sleng), Siem Reap city and the entire Angkor Archaeological Park, and Sihanoukville waterfront. The Phnom Penh to Siem Reap National Road 6 maintains 4G throughout. Kampot and Kep coastal towns have 4G. Remote areas of Mondulkiri and Ratanakiri provinces in the eastern highlands carry 3G or weaker signal. The Cardamom Mountains interior has minimal coverage.

Angkor Wat temple grounds maintain 4G signal, including inside Angkor Thom and the Bayon temple.

ABA and Wing banking apps use under 5 MB per transaction. Budget 400-600 MB per day in cities for maps, messaging, and social media. Siem Reap night market navigation uses 50 MB per evening.
