In Iran, cell phone numbers are a key tool for digital identity verification and access to banking, judicial, administrative and insurance services, as well as many everyday activities. As a result, disconnecting a SIM card can do more than block calls and text messages. It can also cut off access to a wide range of digital services.
Some Iranians said the restrictions on their cell phones were accompanied by the blocking of user accounts and access to banking and government services. They said access was restored only after they deleted critical content or pledged to stop participating in protest-related activities. DW spoke to three people in Iran about the issue.
They have used pseudonyms out of concern for their safety. Sina told DW that he realized his SIM card had been disconnected while returning from university and trying to book a taxi by phone. The 25-year-old said that after visiting a telecommunications center, he received a call from someone claiming to be from the Intelligence Organization of the Islamic Revolutionary Guard Corps (IO-IRGC), who instructed him to go to a specified location to have his SIM card reconnected.
Sina said he was interrogated for about six hours and that his mobile phone was confiscated. He said the return of his SIM card and phone was made conditional on signing a pledge expressing "remorse" for his activist activities and online "propaganda against the system." He said he was also required to publish posts supporting the Islamic Republic to "prove his brotherhood with the system." Several hours later, he said, his family discovered that posts on his Instagram account had been deleted. Only one remained, stating that "the activities of the page are in accordance with the laws of the Islamic Republic of Iran." A month later, he said, he had still not received his SIM card or mobile phone back and was unable to access his social media accounts.
Sorour, a 41-year-old translator at an official translation office in Tehran, said that after her SIM card was disconnected, she went to a location designated by the IO-IRGC, where she was interrogated for hours about her activities on Instagram and X.

Mina, who lives in Isfahan, said she was summoned by an institution she identified as the IRGC Intelligence Organization after posting a comment supporting one of the country's political currents under a post by a foreign-based news outlet.
The 63-year-old said her SIM card and national identification card were blocked after she refused to comply with the summons. According to Mina, the restrictions disrupted her access to bank transfers, administrative systems, online purchases and services that require electronic identity verification and one-time passwords. She told DW she had also been denied access to Sana, the judiciary's electronic system, and was therefore unable to determine whether a case or charges had been filed against her.
