Singapore's Infocomm Development Authority accepts equipment registration for many types of telecommunications and radio equipment, though registration is voluntary for some categories of equipment. The company filing the registration must be a local company with a valid IMDA dealer's license. Registrations are typically based on foreign standard test reports to declare conformity to IMDA's technical standards. IMDA also accepts equipment certification by local or foreign certification bodies recognised by IMDA under a phase II mutual recognition arrangement.
The Singapore Accreditation Council (SAC) works closely with other international bodies on Mutual Recognition Arrangements (MRAs) to allow signatories to mutually recognise reports and certificates issued by an accredited Conformity Assessment Body (CAB) as equivalent to their own standards.

In 2013, the Media Development Authority of Singapore issued guidelines for the Broadcasting Act providing that all online news websites that provide regular reports on Singapore and have significant reach should acquire an individual license. Additionally, any news website that covers an average of at least one article per week on Singaporean news and current affairs over a period of two months and reaches at least 50,000 unique Internet Protocol addresses in Singapore over the same two-month period requires a special license. Furthermore, the licensed sites must also put up a performance bond of SGD $50,000 (USD 42,000), similar to that required for niche TV broadcasters. The new license requires holders to take down content that breaches certain standards within 24 hours of being notified by the Singaporean government.

It is reported that Singapore imposes an identity requirement for SIM registration. Anyone wanting to purchase a SIM card has to provide their national ID card, or a passport in case of foreigners, to activate a new prepaid SIM card. In addition, SIM cards cannot be activated without biometric identification

The Broadcasting Act includes explicit internet regulations since 1996. Internet content providers and ISPs are licensed as a class and must comply with the act’s Class License Conditions and the Internet Code of Practice. Under this regime, ISPs are required to take “all reasonable steps” to filter any content that the regulator deems “undesirable, harmful, or obscene (Conditions of Class Licence, Section 2A (6), Broadcasting (Class Licence) Notification under the Broadcasting Act (Chapter 28) Section 9). In addition, in accordance with Section 2 of the Internet Code of Practice, licensees shall use their best efforts to ensure that prohibited material is not broadcasted via the Internet to users in Singapore. The Infocommunications Media Development Authority issued the Internet Code of Practice in exercise of the powers conferred by Section 6 of the Broadcasting Act (Cap. 28)

The Safe Harbour provisions are encapsulated within ss 193B to 193D and ss 252A to 252C of the Copyright Act. In 1999, Singapore made its first amendments to the Copyright Act to introduce various safe harbor defenses for Internet intermediaries as network service providers. Arising from its obligations under the US- Singapore Free Trade Agreement, Singapore further revised in 2014 the safe harbor defenses in the Copyright Act for network service providers.

The Electronic Transactions Act establishes a safe harbour regime for intermediaries beyond copyright infringements. According to Section 26 of the Act (introduced by the amendment of the Act within the Act 26 of 2012), any network service provider shall not be subject to any civil or criminal liability in respect of “third-party material” in the form of electronic records to which it “merely” “provides access. This exemption of liability is also extended to cover liabilities in respect of data protection obligations with respect to third-party material under the Personal Data Protection Act 2012.

Pursuant to Section 39 of the Criminal Procedure Code, police officers investigating arrestable offenses may at any time access and search the data of any computer they suspect has been used in connection with the offense. No warrant or special authorization is needed. It is reported that the police have seized electronic devices in relation to several investigations in recent years. Penalties for noncompliance can include a fine of up to S$5,000 (approx. USD 3,700), six months in jail, or both.

Telecom licences granted to operators usually contain data retention requirements, which are on average 12 months. The Infocomm Media Development Authority, IMDA reserves the right to require its licensees to retain records as it may deem necessary.

Under Section 11(3), each organisation is required to appoint one or more data protection officers to be responsible to ensure the organisation’s compliance with the Personal Data Protection Act.

Singapore has joined agreements with binding commitments to open transfers of data across borders: the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP, Art. 14.11), Singapore-Australia Free Trade Agreement (SAFTA, Ch. 14 Art. 13), Free Trade Agreement between the Democratic Socialist Republic of Sri Lanka and the Republic of Singapore (Art. 9.9) and the Digital Economy Agreement between the United Kingdom of Great Britain and Northern Ireland and the Republic of Singapore [Art. 8.61-f(2)].

The Personal Data Protection Act 2012 (PDPA) provides a baseline standard of protection for personal data in Singapore. It complements sector-specific legislative and regulatory frameworks such as the Banking Act and Insurance Act. It comprises various requirements governing the collection, use, disclosure and care of personal data in Singapore. The Act came into force in different phases and the provisions concerning data protection were enforced from July 2014.

An organisation may only transfer personal data outside Singapore if it has taken appropriate steps to ensure that:
- it complies with the Personal Data Protection Act (PDPA) obligations in respect of the transferred personal data while it remains in its possession or under its control; and
- the recipient outside of Singapore is bound by legally enforceable obligations to provide a standard of protection to the personal data transferred that is comparable to that under the PDPA (Section 26).
An organisation is deemed to have met the second requirement if the individual consents to the transfer of the personal data to the recipient in that country.

According to the Info-communications Media Development Authority Act, the Info‑communications Media Development Authority, the executive authority for supervising and administrating services in the telecommunications sector, is independent from the government in the decision-making process.

Singapore has appended the World Trade Organization (WTO) Telecom Reference Paper to its schedule of commitments.

Singapore Telecommunications (SingTel), the incumbent telcommunication operator, is currently 52% government-owned.
