Understanding Cambodia's Networks
Cambodia has three major mobile networks. Your eSIM provider's network choice directly impacts your experience, especially in rural areas and near the temples.
Smart — Best Urban Coverage
Best coverage in Phnom Penh, Siem Reap, and major tourist areas. Good 4G/LTE speeds in cities. Used by Airalo.
Metfone — Best Rural Coverage
Best coverage for rural Cambodia and border areas. Used by BNESIM. Good option if visiting temples outside Siem Reap or traveling to provinces.
Cellcard — Moderate Coverage
Moderate coverage, improving but generally less comprehensive than Smart or Metfone.
Coverage by Destination
Phnom Penh
Excellent 4G coverage from all major networks. Any provider works well in the capital. 4G is widely available throughout the city.
Siem Reap & Angkor Wat
Good coverage from Smart and Metfone around Siem Reap and Angkor Wat temple complex. Some remote temple areas may have limited signal.
Rural Cambodia & Provinces
Metfone is the most reliable for rural Cambodia including provincial roads, border areas, and remote temples. Smart coverage can be spotty outside major cities.

- Rural temple visits: For remote temples like Beng Mealea, choose Metfone-based providers for the best coverage.
- Island travel: For Koh Rong and other islands, expect limited coverage. Download offline maps and content before departure.
