This telephone set was issued by Singapore Telecom, which was previously known as Telecoms after the Singapore Telephone Board merged with the Telecommunication Authority of Singapore in 1974. This entity was later renamed Singapore Telecom, or Singtel, as part of a corporatisation programme that began in 1989. Such telephone sets were commonly found in the households and offices in Singapore throughout the 1990s, and they were key communication tools before the arrival of handheld devices.
