Several routes connect you to Cambodia (+855) — landlines, calling cards and modern VoIP services. Pick the one that fits your call volume and budget.
Dial Cambodia directly from any landline or mobile by entering your international exit code, then the country code +855, and finally the local number.
Pre-paid international calling cards remain a convenient, low-cost way to reach Cambodia. Each card gives you a PIN and an access number to place global calls.
Voice-over-IP apps like Skype, WhatsApp and Viber — and business VoIP from TKOS — route calls to Cambodia over the internet, usually at far lower rates than traditional carriers.
The cost of calling Cambodia varies depending on the method and service provider you choose. Compare landline, VoIP and calling-card routes side by side.
VoIP · overview
Cheapest route — internet-based.
Choose TKOS for business-grade calls to Cambodia, or consumer apps like Skype, WhatsApp or Viber for casual chats.
Sign up with an email or phone number, then verify your identity if required.
App-to-app calls are usually free; calls to mobile/landline numbers need a small balance or a subscription plan.
Enter +855 followed by the Cambodia subscriber number (drop any leading 0).
VoIP works on phones, laptops, tablets and desk phones — wherever you have internet.
If audio drops, try switching from cellular to Wi-Fi or move closer to your router.

Press + on a mobile (hold the 0 key), or dial 00 from most countries / 011 from North America.
Dial +855. This identifies Cambodia on the global telephone network.
Type the first part of the local number. Drop the leading 0 if there is one.
The remaining digits route the call to the specific line in Phnom Penh or elsewhere.
