From an iPhone
Open the Phone app, press and hold 0 until a + appears, then type 855 followed by the local Cambodia number. Or use Kinvo in Safari — no dialer permissions needed.
From Android
Open your Phone app, long-press 0 to get +, then dial +855 + the number. In Chrome, open kinvophone.com and call directly without touching your carrier plan.

Landlines don't have a + key, so use the full exit code: 011 855 then the local number. Check with your phone provider that international calling is enabled to avoid blocked calls.
How to Call Cambodia For Free
If the person you're calling in Cambodia has a smartphone with internet access, the cheapest way to call them is free: use WhatsApp, FaceTime, Telegram, Signal, or Google Meet. Both sides need the same app, and calls travel over the internet rather than the phone network — no per-minute fees, no country code needed.
For calling any regular Cambodia landline or mobile number — the kind that requires dialing +855 — there is no truly free option, because someone has to pay the termination fee to connect the call. Kinvo is the lowest-cost option for dialing Cambodia phone numbers, starting at $0.25/min with no subscription, compared to $1–$3/min at most US carrier rates.
Cambodia Calling Tips
Drop the leading 0 from Cambodian numbers. Phnom Penh area code is 023 (becomes +855 23). Mobile numbers start with 01, 06, 07, 08, or 09. Khmer is the official language. Mobile phones are the primary means of communication. Call quality in rural areas can be inconsistent.
