Reference excerpt

Singapore Telecommunications Limited, trading as Singtel, is a Singaporean telecommunications conglomerate, the country's principal fixed-line operator and one of the four major mobile network operators operating in the country.

Overview The company is the largest mobile network operator in Singapore with 4.5 million subscribers and through subsidiaries, has a combined mobile subscriber base of 800 million customers as of 31 March 2025. The company was known as Singapore Telecom until 1992. Singtel provides ISP, IPTV (Singtel TV) and mobile phone networks and fixed line telephony services. Singtel has expanded aggressively outside its home market and owns shares in many regional operators, including full ownership of Australia's second largest telco Optus and 27.5% of Bharti Airtel, the second largest carrier in India. Singtel controls significant market share in Australia and Singapore, with 82% of the fixed-line market, 47% of the mobile market and 43% of the broadband market in Singapore. Singtel is also the second-largest company by market capitalisation listed on the Singapore Exchange and is majority owned by Temasek Holdings, the investment arm of the Singapore government. Singtel is an active investor in innovation companies through its Singtel Innov8 subsidiary, founded in 2011 with S$200 million start up capital.

History

Pre-1970s In 1882, Singapore's phone network was operated by the Oriental Telephone and Electric Company (OTEC), which setup a branch in July 1882. The Public Telephone Exchange set up 60 telephone lines connecting local businesses of that era. In 1907, OTEC was replaced by a new Central Telephone Exchange in Hill Street. The Singapore Telephone Board (STB) was incorporated as a statutory board with exclusive rights to operate telephone service within Singapore in 1955.

1970s-2000s On 1 April 1974, STB was merged with Telecommunications Authority of Singapore (TAS, Telecoms or Singapore Telecom). Before 1974, STB was responsible for local services, while TAS provided international services. In 1982, the Postal Service Department was merged with TAS, retaining the same name. In March 1992, Singapore Telecommunications Private Limited (SingTel) was incorporated as a separate company. The remainder of Telecoms became Singapore Post Private Limited and a smaller Telecommunications Authority of Singapore (later becoming Infocomm Media Development Authority). SingTel later introduced the call zone service, made defunct in 1997. In October 1993, SingTel became a public company (Singapore Telecommunications Limited) via an IPO. In 1997, SingTel was compensated $1.5 billion by the Singaporean Government for early termination of its monopoly, based on projected earnings lost between 2000 and 2007 due to its loss of monopoly.

2000-2010 In 2000, SingTel lost its domestic monopoly in Singapore, with the government deregulating the telecommunications industry. In March 2001, Singtel purchased Optus for between $7.4 billion to $8.5 billion In April 2001, it was awarded a 3G license. In 2003: SingTel sold 60% of Singapore Post (SingPost) in May during an IPO in an effort to focus on its core telecommunications services business. It also divested its stakes in Yellow Pages in June, its directory business to CVC Asia Pacific and J.P. Morgan Partners Asia for S$220 million. In 2005, SingTel launched its commercial 3G services. On 20 July 2007, mio TV, later renamed Singtel TV, was launched commercially on 20 July 2007 and began its services on 21 July 2007. In 2008, SingTel and Apple jointly announced that SingTel would be the first mobile operator to launch the iPhone 3G and its services to Singapore in June. In June 2008, SingTel becomes the title sponsor of the inaugural Singapore Grand Prix in Singapore. On 10 July 2009, SingTel launched the iPhone 3GS commercially in Singapore.

2011–2014 In May 2011, SingTel announced that they would be aiming to double the size of its satellite business, with two additional launches by 2013. In November 2011, SingTel launched Singapore's first e-book provider, Skoob, which was available through the web, iOS or Android. In March 2012, SingTel acquired mobile advertising technology company Amobee in March 2012 for $321 million. In December 2012, SingTel was fined $300,000 for breaches of the Service Resiliency Code by the IDA., and also started providing 4G LTE services across Singapore. In March 2013 SingTel announced the sale of its entire 30% stake in Warid Telecom (Private) Limited to Warid Telecom Pakistan LLC which took place on 15 March 2013. On 1 August 2013, mio TV was officially renamed SingTel TV. On 5 November 2013, SingTel shutdown its Skoob e-book store. In May 2014, SingTel was fined $6 million for its Bukit Panjang fire in the previous year. This is the highest fine imposed on a telco in Singapore. In August 2014, SingTel announced it was joining forces with five other global companies, including Google, to build a super-fast undersea data cable linking the U.S. and Japan. In 2014 Bharti Airtel became first telecommunication company to serve 4G internet in India.

Worked examples

Example 1 — a first encounter with Singtel

Start with the simplest possible case. Write down what Singtel claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Singtel before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Singtel ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Singtel

In research: Singtel appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Singtel in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Singtel is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1879 establishments in Singapore, Companies in the S&P Asia 50, Companies in the Straits Times Index, so understanding it makes those chapters shorter.
In everyday life: Look for Singtel outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
