Telegram was open and working in Iran without any VPN or other circumvention methods in May 2015. In August 2015, the Iranian Ministry of ICT asserted that Telegram had agreed to restrict some of its bots and sticker packs in Iran at the request of the Iranian government. According to an article published on Global Voices, these features were being used by Iranians to "share satirical comments about the Iranian government". The article also noted that "some users are concerned that Telegram's willingness to comply with Iranian government requests might mean future complicity with other Iranian government censorship, or even allow government access to Telegram's data on Iranian users". Telegram has stated that all Telegram chats are private territory and that they do not process any requests related to them. Only requests regarding public content (bots and sticker packs) will be processed. In May 2016, the Iranian government asked all messaging apps, including Telegram, to move all Iranian users' data to Iranian servers. On 20 April 2017, the Iranian government completely blocked Telegram's new voice calls, a service that allows individuals to make calls via secure, end-to-end encryption, and keep their conversations private.Mahmoud Vaezi Chief of Staff of the President of Iran said reason for blocking Telegram free voice calls is so Iranian corporations keep revenue from voice calls.

On 30 December 2017, during anti-government demonstrations across Iran, Telegram has shut down a channel of the Iranian opposition that published calls to use Molotov cocktails against the police, after receiving a complaint from the Iranian government. Pavel Durov explained that the reason for the blocking was a "no calls to violence" policy and confirmed that criticizing local authorities, challenging the status quo and engaging in political debate were seen as "OK" by the platform, while "promoting violence" was not. The opposition group promised to comply with Telegram rules and created a new channel which amassed 700,000 subscribers in less than 24 hours. On December, 31, the Iranian government announced that Telegram has been "temporarily restricted" in order to "ensure calm and security" after the company said it refused to shut down peaceful protesting channels. On January, 13, the app was unblocked by an order of the president Hassan Rouhani, who said that "more than 100,000 jobs had been lost" in Iran as a result of the ban on Telegram. Channels of the opposition remain operational.

In March 2018, Iran's chairman for the Committee for Foreign policy and National Security Alaeddin Boroujerdi announced that Telegram has been targeted to be fully blocked in Iran by 20 April 2018, citing Telegram's role in facilitating the winter protests and the need to promote local apps. President Rouhani agreed with the need to break Telegram's monopoly in Iran, but maintained that he was opposed to a new blockade and did not see it as an effective measure to promote local apps. Iranian MP Mahmoud Sadeghi noted that during the two weeks that Telegram was blocked in January 2018, 30 million Iranians (75% of Telegram's users in Iran) did not start using local messaging apps, but instead turned to VPN services to circumvent the block, rendering the blockade ineffective.

Telegram was blocked by the government on May 1, 2018.

Russia 

On 16 May 2017, Russian media reported that Roskomnadzor was threatening to ban Telegram. On 13 April 2018, Telegram was banned in Russia by a Moscow court, due to its refusal to grant the Federal Security Service (FSB) access to encryption keys needed to view user communications as required by federal anti-terrorism law. Enforcement of the ban was attempted by blocking over 19 million IP addresses associated with the service. However they included those used by Amazon Web Services and Google Cloud Platform, due to Telegram's use of the providers to route messages. This led to unintended collateral damage due to usage of the platforms by other services in the country, including retail, Mastercard SecureCode, and Mail.ru's Tamtam messaging service. Users used VPNs to bypass the ban as a result. On 17 April 2018, Russian authorities asked Apple and Google to pull the service from their stores as well as APKMirror, however Apple and Google refused the request. On 28 March 2018, Roskomnadzor reportedly sent a legally binding letter to Apple asking it to remove the app from the Russian version of its App Store and block it from sending push notifications to local users who have already downloaded the app. On 27 December 2018, the largest search engine in Russia, Yandex, removed telegram.org from their search results.
