The Online Content Regulations, which were first introduced in 2018 and later replaced by the Online Content Regulations of 2020, require online content service providers to have an operating license. The license is applicable to providers who cover news, entertainment, educational, and religious content through blogs, social media pages, and similar services. Therefore, on top of traditional media websites, online TV and radio channels, individual bloggers and podcasters are required to have a license.
According to the regulations, a person can only provide content services after obtaining a license from the Tanzania Communications Regulatory Authority (TCRA). There are four categories of online content licenses available for providers of predominant news and current affairs: entertainment content, educational and religious content, and simulcasting. Upon successful application, the licensee is required to pay an initial fee of TZS 1,000,000 (USD 433 approx.) for a news and current affairs license, TZS 500,000 (USD 216 approx.) for an entertainment and education license or religious content license, and TZS 200,000 (USD 87 approx.) for a simulcasting license. The same fees apply for annual payments and license renewal, and the license is valid for three years. If a licensee breaches the terms and conditions of the license, the license may be suspended or revoked by the TCRA. The licensee is notified of the revocation or suspension and the reasons for it and must surrender the license to the TCRA within seven days after service of the revocation or suspension notice. In addition, the failure to adhere to these regulations makes the service provider liable to a fine of not less than five million shillings (equivalent to approx. 2,150 USD) or imprisonment for a term of not less than 12 months or both.
It is reported that content providers used to be able to register and get a single license to offer different types of content, but with the 2020 Regulations, they are required to obtain numerous permits based on the content they offer and can incur exorbitant licensing fees. In addition, it is reported that as a result of this licensing regime, some blogs were closed down.

In October 2023, the Tanzania Communications Regulatory Authority (TCRA) regulated the use of virtual private networks (VPNs). It is reported that VPN use without an official permit is prohibited in the country, and individuals and companies that wanted to obtain permission were required to notify the TCRA of their VPN use by October 2023. Penalties for non-compliance include fines of at least TZS 5 million (about USD 2,000) or a minimum of 12 months in jail.

According to Section 2 of the Electronic and Postal Communications (Electronic Communications Equipment Standards) Regulations (2018), these Regulations apply to electronic communications equipment imported or manufactured for use in the United Republic and intended for connection to any electronic communications network for the purpose of receiving or transmitting electronic communication signals.
Part III sets out the procedures for type approval of electronic communications equipment, including the manufacturer’s declaration of conformity. Under Section 6, manufacturers must declare that all electronic communications equipment conforms to international and national standards before it can be approved for use in the United Republic.
The 2018 Regulations repealed and replaced the Electronic and Postal Communications (Electronic Communications Equipment Standards) Regulations (2014), which had established the same type approval procedure for electronic communications equipment under Section 6.

Pursuant to Regulations 4 and 5 of the Electronic and Postal Communications (Investigation) Regulations, any individual's communications may be intercepted by the Director General of the Tanzania Intelligence and Security Service or the Director of Criminal Investigations for purposes including, but not limited to, the preservation or protection of national security, and the safeguarding of public safety, economic well-being, or the interests of the country. In accordance with Regulations 8 and 12, where the Director of Criminal Investigations intends to intercept communications, they are required to apply for a warrant from the Inspector General of Police, but not from a judge.

The Cybercrimes Act (2015) establishes a safe harbour regime for intermediaries for copyright infringements. Pursuant to Sections 39-44 of the Act, service providers are exempt from liability for information stored, transmitted, hyperlinked on their networks, or accessed through their search engines, provided they comply with certain conditions. These conditions require that the service provider neither initiates the transmission nor selects or modifies the information. Furthermore, if a service provider becomes aware of illegal content on their platform through means other than an order from a public authority, they are obligated to promptly notify the relevant authority. Additionally, upon becoming aware of such illicit content or receiving a takedown notice, the provider must take immediate action to remove or restrict access to the information. These provisions aim to protect intermediaries while encouraging the responsible management of illegal content on their platforms.

According to the Electronic and Postal (Online Content) Regulations 2018 (last amended in 2020), the application service licensee holders are required to terminate or suspend the subscriber account within two hours after being reported for sharing prohibited content (Section 11.3). While the previous regulation required online platforms to take down alleged illegal content within 12 hours, the current regulation forces license holders — such as the hosts of discussion forums — to remove prohibited content immediately. When a subscriber to a forum uploads alleged illegal content, the license holder must notify the subscriber within two hours. If the subscriber fails to take down content within two hours of getting the notice, the license holder must revoke the subscriber’s access to the platform. In addition, according to Section 9.d, providers are required to use moderating tools to filter prohibited content.

- For the performance of a contract between the data subject and the data collector or the implementation of pre-contractual measures taken at the request of the data subject.
- For the conclusion or performance of a contract concluded or to be concluded in the interest of the data subject between the collector and another person.
