Iran’s judiciary has blocked newly introduced voice calls on Telegram, the most popular messaging app in the country, state media reported today. The blockage follows the arrest last month of 12 people who ran popular reformist channels on Telegram, ahead of a presidential election next month. It was not clear if the blockage of voice calls, which Telegram introduced worldwide last week, was political or designed to protect the commercial interests of domestic phone companies.
“We gave the authorisation for the establishment of Telegram’s voice call service on Friday… but it was blocked by a judicial order,” Telecommunications Minister Mahmoud Vaezi told reformist newspaper Shargh.
“You should ask the judiciary for the reason.”
Last month, the conservative-dominated judiciary blocked the online navigation app Waze because it was designed in Israel, which Iran does not recognise.
Telegram CEO Pavel Durov confirmed the blocking of voice calls.
“In Iran, where Telegram has some 40 million active users, Telegram voice calls have been completely blocked by the country’s internet providers and mobile operators following an order from the judiciary,” he wrote on his official channel.
“Telegram has historically had problems with regulators in some parts of the world because, unlike other services, we consistently defended our users’ privacy and have never made any deals with governments.”
Iranian officials have previously said there were around 20 million Telegram users in the country, which has a population of some 80 million.

“Some of these people have been arrested on national security charges and some… for committing crimes against public decency and publishing obscene content,” deputy judiciary chief Gholamhossein Mohseni Ejeie told the Mizan Online news agency last week.
