Pursuant to Section 5 of the Telegraph Act and the Telegraph Rules, the Government has the power to temporarily possess licensed telegraphs and order the interception or disclosure of messages sent through such devices. The definition of a telegraph is fairly wide: it means any appliance, instrument, material, or apparatus used (or that is capable of being used) for transmission or reception of signs, signals, writing, images, and sounds or intelligence of any nature by wire, visual, or other electromagnetic emissions, radio waves or Hertzian waves, or galvanic, electric, or magnetic means. It is not clear whether a court order is required to access the data.

The Information Technology Act establishes a safe harbour regime for intermediaries for copyright infringements. Section 79 of the Act provides intermediaries with qualified immunity for unlawful content as long as they follow the prescribed due diligence requirements and do not conspire, abet or aid an unlawful act. However, the protection lapses if an intermediary with "actual knowledge" of any content used to commit an unlawful act or, on being notified of such content, fails to remove or restrict access to it.

The Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Rules of 2021 establish a safe harbour regime beyond intermediaries for copyright infringement. According to Rule 3.1(d), an intermediary, after receiving 'actual knowledge' through a court order or by being notified by a government agency, must remove information that is prohibited by law in relation to the interest and sovereignty of India, the security of the state, friendly relations with foreign states, public order, decency or morality, contempt of court, defamation, incitement to an offence or information which violates any law which is in force. Such information has to be removed within thirty-six hours from receipt of actual knowledge by the intermediary.
In addition, "significant social media intermediaries", defined as having more than five million registered Indian users, need to observe additional due diligence requirements to claim the immunity/safe harbour available. Rule 6 of the Information Technology Rules provides that even if a social media intermediary does not meet this user threshold, the Central Government may still require an intermediary to meet these additional obligations if it believes that their operations create a material risk of harm to the sovereignty and integrity of India or to the security of the State. This discretion to the Central government may lead to the arbitrary imposition of additional obligations on certain intermediaries. The additional due diligence requirements include appointing certain personnel for compliance, enabling identification of the first originator of the information on its platform under certain conditions, and deploying technology-based measures on a best-effort basis to identify certain types of content.

According to the Regulation on the Use of Aadhaar e-KYC Service of the Unique Identity Authority of India (UIDAI) for Issuing New Mobile Connections and Re-Verification of Existing Subscribers via OTP-Based Authentication, Indian citizens are required to register their SIM card with their Aadhaar Card (a type of national identity card). Foreigners have to provide their passport, a photocopy of their Indian visa/ travel permit, a passport-sized photo and contact details.

According to Art. 3.3 of the Information Technology Intermediaries Guidelines Rules, intermediaries are required to deploy technology-based automated tools or appropriate mechanisms with appropriate controls for proactively identifying and removing or disabling public access to unlawful information or content.

Section 69 of the Indian Information Technology Act (IITA) requires intermediaries to extend all facilities and technical assistance to intercept, monitor or decrypt information as well as to provide information stored in a computer or provide access to a computer resource when called upon to do so by certain agencies. This extends to online intermediaries, which are required to designate an officer to facilitate the execution of such orders. Intermediaries that fail to meet these obligations may be punished with imprisonment of up to seven years.

According to Art. 4.2 of the Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Rules of 2021, a significant social media intermediary (defined as a social media intermediary having a number of registered users in India above five million) providing messaging services must enable identification of the first originator of the information on its computer resource as may be required by a judicial order or an order passed by a competent authority. In complying with an order for the identification of the first originator, a significant social media intermediary will not be required to disclose the contents of the electronic message related to the first originator or other users. No order must be passed in cases where there are less intrusive means of identifying the originator of the information.

According to Art. 8 of the The Information Technology (Procedure and Safeguards for Interception, Monitoring and Decryption of Information) Rules of 2009, an officer so designated by the Central Government under the Rules (known as 'Designated Officer') can on the receipt of a request from any nodal officer of a government organisation or a competent court or by an order of any agency of the government can block access by the public to any information transmitted, received, stored or hosted in any computer resource. The request will be examined by a committee consisting of the designated officer, its chairperson, and representatives, who shall determine if the information must be blocked.

According to the Temporary Suspension of Telecom Services (Public Emergency or Public Safety) Rules, 2017, national or state-level officials are allowed to issue temporary suspension orders to shut down telecom services in times of public emergency or threats to public safety. However, each order should contain reasons for shutdowns of telecom services and should be forwarded to a review committee for assessment.

India has not yet enacted specific legislation concerning data protection. Currently, the regulation of personal data processing is primarily governed by the Information Technology Act of 2000 and the Information Technology (Reasonable Security Practices and Procedures and Sensitive Personal Data or Information) Rules of 2011, which were promulgated under the Act. Additionally, sector-specific laws, such as those applicable to the financial services and telecommunications sectors, contribute to the regulatory framework.
The Digital Personal Data Protection Act was enacted on 11 August 2023 and will come into force on a date to be notified by the Government of India. As of February 2024, the Act has not yet become effective. Once in effect, the Act is expected to establish a comprehensive data protection regime in India.

Section 5 of Direction No. 20(3)/2022-CERT-In mandates data centres, virtual private server providers, cloud service providers, and virtual private network service providers to mandatorily collect and retain certain subscriber-related information accurately for a minimum period of five years after the subscriber is no longer availing the underlying services. These data sets include subscriber names, period of hire including dates, IPs allocated and used, e-mail address along with IP and time stamp used at time of registration, purpose of availing the services, verified address and contact numbers, and ownership pattern of subscribers. Virtual asset service providers, virtual asset exchange providers and custodian wallet providers must also maintain KYC information and records of financial transactions for a period of 5 years. Specific to transaction records, Direction No. 20(3)/2022-CERT-In states that information must be maintained accurately in such a way that individual transactions can be reconstructed along with the relevant constituents such as IP addresses, time zones, transaction ID, public keys or equivalent identifiers, addresses or accounts involved, nature and date of transaction, amount transferred, etc.

Bharat Sanchar Nigam Limited, the incumbent, is fully owned by the Government of India. BSNL (Bharat Sanchar Nigam Ltd.) provides all types of telecom services, namely telephone services on landlines, Wireless Local Loop and GSM mobile, Broadband, Internet, leased circuits and long-distance telecom services.

According to the License Agreement for Provision of Internet Services, the Internet Service Provider licensee shall maintain all commercial records, call detail records, exchange detail records, and IP detail records with regard to the communications exchanged on the network. Such records shall be archived for at least two years for scrutiny by the Licensor for security reasons and may be destroyed thereafter unless directed otherwise by the Licensor.

India does not mandate functional separation for operators with significant market power (SMP) in the telecom market. However, the Accounting Separation Regulation is applicable to all the service providers having aggregate turnover of not less than rupees one hundred crore (approx. 12,182,700 USD) during the accounting year for which report is required to be submitted from operations under the telecom license(s) issued to them under section 4 of the Indian Telegraph Act 1885. The telecom service providers are required to submit their audited accounting separation reports based on a historical cost basis every year and on a replacement cost basis every second year within seven months of the end of the accounting year.

According to the Consolidated Foreign Direct Investment (FDI) Policy Circular 2020, foreign direct investment in telecom services (including fixed, mobile, and internet) is subject to compliance with both licensing and security conditions by the licensees and investors. These regulatory requirements have been in place since the implementation of the Consolidated FDI Policy Circular 2013 (Section 6.2.15). The conditions are outlined in the License Agreement for Unified License, which applies to all telecom services across the country.
Internet Service Providers (ISPs) and Telecom Service Providers (TSPs) in India must comply with the License Agreement for the Provision of Internet Services. Additionally, TSPs are required to adhere to two separate license agreements: the Cellular Mobile Telephone Service (CMTS) License Agreement, which governs cellular mobile communications, and the License Agreement for the Provision of Basic Telephone Services (BTS), which covers landlines. Reports suggest that these licenses provide the government with significant access to communication data held and processed by service providers.
It is also noted that India’s one-time licensing fees—approximately USD 500,000 for a service-specific license or USD 2.7 million for an all-India Universal License—act as a barrier to market entry for small and medium-sized enterprises.
