Free: App-to-App Calls
Both people need the app and internet. No charges, no limits.
1. Facebook Messenger — #1 in Cambodia
Messenger is king in Cambodia — not WhatsApp. Cambodia is one of the most Facebook-centric countries in the world. Most Cambodians got their first internet experience through Facebook, and Messenger is the default communication tool. Free voice and video calls work well in urban areas.
Important: Don't assume WhatsApp. Ask your Cambodian contact for their Facebook/Messenger first. Many Cambodians don't use WhatsApp at all.
2. WhatsApp — Used by Expats
WhatsApp has some presence in Cambodia, primarily among expats, digital nomads, and internationally-connected Cambodians. If you're calling someone in the expat community in Phnom Penh or Siem Reap, WhatsApp may work — but Messenger is the safer bet for locals.
3. Telegram — Growing
Telegram has been gaining traction in Cambodia, especially among younger users and the tech community. The digital nomad scene in Phnom Penh and Siem Reap uses Telegram extensively for group communication.
4. FaceTime — Limited
iPhone market share in Cambodia is relatively low — under 15%. Android dominates, with Samsung and Chinese brands (Oppo, Xiaomi, Huawei) being the most popular. FaceTime is uncommon.
Calling Cambodian Phone Numbers
Cambodia is moderately priced to call:
| Service | Mobile Rate | Landline Rate | Notes |
|---|---|---|---|
| BubblyPhone | $0.24/min | $0.24/min | Browser, iOS, Android |
| Google Voice | $0.15/min | $0.09/min | US Google account required |
| Rebtel | $0.10/min | $0.07/min | Calling plans available |
| AT&T / Verizon | $3.00-5.00/min | $3.00-5.00/min | Up to 35x more expensive |
Our honest take: Google Voice ($0.09/min mobile, $0.04/min landline) is cheaper than BubblyPhone ($0.24/min) for Cambodia. But Facebook Messenger is free and it's what Cambodians actually use — try that first.

Google Voice ($0.04/min landline) or BubblyPhone ($0.24/min). Many Cambodian businesses also have Facebook pages with Messenger — try that first.
