How do you dial a plus 60320 number?

Telephone country code +60 is Malaysia, and +60 3 is the area code for Kuala Lumpur. If you are using a GSM mobile phone, just dial the number that way, beginning with the plus symbol. Otherwise, replace the plus symbol with the international access prefix for outbound calls from your current location. The most commonly used prefix is 00, but there are several other prefixes used in some places, and there are some places that have multiple different prefixes for specific purposes.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
