Pros: Lowest price per GB, fast activation, Cambodia coverage on Metfone. Cons: Newer brand, smaller community than Airalo.
Cambodia 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 analysis
Metfone 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.
Activation
Install your e-sim before landing at PNH (Phnom Penh International) or REP (Siem Reap Angkor). Scan the QR code in Settings, then Mobile Data, then Add eSIM. Metfone registers within 3 minutes.
The tuk-tuk and PassApp ride-hailing apps work immediately on Metfone 4G. Tethering is active on all 6 plans. Angkor Wat temple grounds maintain 4G signal, including inside Angkor Thom and the Bayon temple.
Data usage tips
PassApp Taxis and Grab Cambodia each use under 15 MB per trip in Phnom Penh. The Angkor Wat audio guide app for temple complexes downloads 200 MB offline and then uses near-zero data. 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.
