How to Call Cambodia from Australia: 3 Ways
Most people make calls to Cambodia in one of 3 ways.
- Calling card. You dial a local access number in Australia, so the card works from any landline or mobile phone. It needs no internet connection and no new SIM card. International rates to Cambodia start at 5.8c a minute.
- Your calling plan. Many calling plans charge a rate per minute for international dialling, and some block it. Check the rate to Cambodia before you call.
- Internet calling apps (VoIP). Calls are free when both people have the same app and a data plan or Wi-Fi. Call quality depends on the internet connection at both ends.
A calling card suits calls to landlines and to people with a weak internet connection.
Why a Call to Cambodia Does Not Work
- Keeping the 0 after 855, e.g. 0011 855 012 345 678 instead of 0011 855 12 345 678.
- Thinking a mobile number with an extra digit is a typo. Numbers on 018, 031, 071, 076, 088, 096 and 097 have 7 digits after the prefix, so they are one digit longer than other mobiles.
- Mistaking 031 or 071 for a landline code. Both are mobile prefixes; the provincial landline codes are 023 to 026, 032 to 036, 042 to 045, 052 to 055, 062 to 065 and 072 to 075.
- Assuming the exit code from Cambodia is 00. The ITU lists Cambodia’s international prefixes as 001 and 007; from a mobile, + is the simplest choice.
- Expecting daylight saving. Cambodia stays on UTC+7 all year, so the time gap to Australia changes only when Australian clocks change.
- Your mobile plan may block international calls, or need extra credit for them. A phone card avoids this, because you dial an Australian access number first.
- On a phone card, the overseas number goes in after the access number and PIN, and ends with #.
