International IDD Calls From Singapore

Many telecom providers supply reduced rate International Direct Dial (IDD) telephone calls. 

The IDD prefix is the international prefix required to dial a call from the country listed to another country. This is followed by the country code for the country being called. Singapore has multiple IDDs, with each one used by a different long-distance carrier.

Generally, better quality connections (often called "premium" by the suppliers) are more expensive than calls made on lower rate ("budget") where the line may crackle and have a time lag.

Making an IDD call 

When dialing overseas, first dial the IDD number, followed by the country code and the recipient's telephone number (including area code). If the local area code begins with "0", omit this after dialing the IDD prefix.

• Example: IDD prefix + Country Code + Local area code + Number
