Dialing Tips
- Remove the leading 0: When dialing internationally, drop the trunk prefix (0) that is used for domestic calls in Cambodia.
-
Use the + notation: From a US mobile phone, use
+855instead of011 855. - Verify the number length: Numbers in Cambodia have 8 or 9 digits after +855. If your call does not connect, check that no digit is missing or doubled.
-
Save contacts in international format: Always store phone numbers with the full
+855prefix so they work from any country.
