Official description
Figures provided includes total retail outgoing international call minutes as well as transit minutes.
For comparison purposes, figures from previous years will also be adjusted accordingly. This change has been applied retroactively from Jan 2001. Further, starting from Jan 2001, traffic from other service providers such as ISR operators has also been included.
Since Jul 2004, IDA has also expanded on the reporting of international telephone services to include all Service-Based Operators (SBO), resulting in a marked increase in the minutes reported from Jun 2004. Part of the increase is also due to monthly traffic fluctuations.
This monthly IMDA dataset reports outgoing retail international telephone call minutes, including transit traffic, from January 1999 to April 2016. Each record pairs a month with the corresponding number of call minutes. It can be used to study historical international voice-traffic demand and changes in Singapore's telecommunications usage.
