Mobile networks & coverage in Cambodia

  • Metfone

Why travelers love it

Strong 4G coverage in Phnom Penh, Siem Reap, Sihanoukville and other urban centers. 5G is available in major cities on select networks; rural coverage can be variable.

eSIM vs roaming in Cambodia

Using your home plan's roaming in Cambodia usually means pay-as-you-go rates or daily add-ons — convenient, but easy to overspend on. A Simology eSIM is a fixed prepaid plan you buy before you travel, so you know the cost up front.

Insider tips

  • Public Wi‑Fi can be unreliable — use your eSIM for secure, consistent access when navigating, booking tours, or using mobile payments.
  • Dry season (November to April) is the most comfortable for temple visits and coastal trips; rainy season brings lush landscapes but occasional road disruptions.
