Iran blocks SIM cards, digital access to silence dissent, DW investigation finds
Multiple activists, journalists, and physicians have been denied access to essential services including medical practice, banking, and legal proceedings; one activist detained for six hours of interrogation.
Compliance or isolation—no middle ground.
Mark
So the blocking of a SIM card—that's not just about stopping phone calls, is it?
Mimi
No. In Iran, your SIM card is your digital identity. It's how you access your bank account, how you prove who you are to government systems, how you get prescriptions filled. Blocking it cuts you off from all of that at once.
Luke
But we should be clear: the source material documents three named cases and references several others who posted on social media. That's real and significant, but it's not a comprehensive count of how many people this is happening to.
Mark
What happens when someone's SIM card gets blocked? Is there a process?
Mimi
According to what these people reported, authorities contact them, summon them to a location, interrogate them about their online activity. Then they're told: delete your posts, pledge to stop activism, maybe post something supporting the government. Only then do they get their phone back.
Luke
And that's what these three people say happened to them. The Defending Free Flow of Information organization reported in 2025 that this was happening to journalists and activists without judicial orders, but we don't have a detailed breakdown of how widespread it is or how many times it's occurred.
Mark
Is there any legal recourse? Can someone challenge this?
Mimi
That's the troubling part. There's no formal process, no charges filed, no court order. One woman couldn't even find out if a case had been opened against her. She just woke up blocked.
Luke
Right. The source material is clear that there's an absence of accountability mechanisms and no obvious avenue to challenge the restrictions. But we should note that we don't have statements from Iranian authorities explaining their rationale or defending the practice.
Mark
So someone like Reyhaneh Saeedi, the doctor—she can't practice medicine?
Mimi
Exactly. She can't issue prescriptions, can't renew her licenses. Her identification card was deactivated too. She's been blocked for months, and this is the second time it's happened to her.
Luke
And she's stated publicly on Instagram that she received no formal ruling and no explanation. That's her account of it. We don't have a response from the authorities.
Mark
What does this tell us about how the government operates?
Mimi
It's a form of pressure that doesn't require a trial or a conviction. It just requires that you stop speaking. One former political prisoner wrote that the government's policy is to apply pressure that pushes people toward obedience or withdrawal from activism. That's the mechanism.
Der Puls
- Iranian security forces are weaponizing SIM card disconnections to punish dissent, cutting activists off not just from communication but from banking, healthcare, legal systems, and basic identity verification.
- Affected individuals — including a 25-year-old student, a translator, a physician, and an actress — describe being summoned for hours of interrogation, their phones confiscated, their social media accounts purged without their consent.
- Restoration of access comes at a price: signing loyalty pledges, deleting critical posts, and publicly declaring support for the Islamic Republic — a coerced performance of compliance with no legal basis.
- For those who refuse or cannot comply, the consequences compound: one woman in Isfahan found both her SIM card and national ID deactivated, leaving her unable to transfer money, access courts, or even determine whether charges had been filed against her.
- The practice operates in a legal void — no judicial orders, no formal charges, no notification, and no mechanism for those targeted to challenge or even understand the restrictions imposed upon them.
In Iran, the severing of a SIM card has become something far more consequential than the silencing of a voice — it is the erasure of a person from the infrastructure of modern existence. Authorities have systematically disconnected activists, journalists, and physicians from banking, courts, medical licensing, and identity systems, conditioning restoration on public pledges of loyalty and the deletion of dissenting content. This practice, documented across multiple cases by Deutsche Welle, operates without judicial oversight or formal charges, placing it beyond any legal challenge by those it targets. It is, in essence, a new grammar of control — one written not in laws, but in the architecture of digital life itself.
In Iran, a SIM card is not simply a communication tool — it is the key to banking, hospitals, courts, government offices, and the administrative systems that define modern life. When authorities disconnect one, they do not merely silence a person; they sever them from the infrastructure required to live and work. A Deutsche Welle investigation has documented how this mechanism has been turned against activists, journalists, and critics, with no formal legal process and no transparency.
Sina, 25, discovered his SIM card had been cut while trying to book a taxi home from university. He was directed to a location controlled by the Intelligence Organization of the Islamic Revolutionary Guard Corps, where he was interrogated for six hours. The terms for restoring his access were explicit: sign a statement of remorse, pledge to stop posting critical content, and publish pro-government posts to demonstrate loyalty. His Instagram had already been scrubbed — most posts deleted, replaced with a single message affirming legal compliance. A month later, he had neither his phone nor his SIM card back.
Sorour, a 41-year-old translator in Tehran, was summoned after her SIM was disconnected and interrogated about her activity on Instagram and X. She was ordered to make her accounts private and pledge never to advocate for political prisoners or support protesters — a reference to the nationwide demonstrations that erupted in late December 2025. Mina, 63, living in Isfahan, was blocked after commenting in support of a political current under a foreign news outlet's post. When she refused a summons, both her SIM card and national identification card were deactivated. She could no longer transfer money, make purchases, access government systems, or determine through the judiciary's electronic platform whether any charges had been filed against her.
The pattern reaches further. Former political prisoner Zia Nabavi discovered his SIM had been cut while at a doctor's office, needing his phone to access banking. Physician and activist Reyhaneh Saeedi reported her SIM blocked for months — for the second time — effectively preventing her from practicing medicine, issuing prescriptions, or renewing her medical licenses. She received no ruling, no notification, and no explanation. Actress Shaghayegh Dehghan similarly reported her SIM blocked, with no clarity about who had ordered it or why.
What gives these disconnections their particular force is the architecture of Iranian digital life, where a SIM card underpins access to nearly every essential system. The Defending Free Flow of Information organization documented in 2025 that these blockades occur without judicial orders, leaving those targeted with no legal recourse and no avenue to challenge or even learn the reason for their isolation. The message to those affected is unambiguous: comply, or be erased from the systems that make ordinary life possible.
In Iran, a SIM card is not merely a way to make phone calls. It is the key that unlocks access to banks, courts, hospitals, government offices, and the basic infrastructure of modern life. When authorities disconnect one, they do not simply silence a voice—they erase a person from the digital systems that govern everything from medical licensing to money transfers. A Deutsche Welle investigation has documented how this tool has become a mechanism of control, wielded against activists, journalists, and critics with little transparency and no formal legal process.
Sina, 25, discovered this when he tried to book a taxi home from university and found his SIM card dead. What followed was a call from someone claiming to represent the Intelligence Organization of the Islamic Revolutionary Guard Corps, directing him to a specific location. There, he was interrogated for six hours. His phone was taken. When it was returned, the terms were explicit: sign a statement expressing remorse for his activism, pledge to stop posting content critical of the system, and publish posts supporting the Islamic Republic to demonstrate his loyalty. His Instagram account had already been cleaned—most of his posts deleted, leaving only a single message stating that his page's activities complied with Iranian law. A month later, he still had not received his SIM card or phone back, and his social media accounts remained inaccessible.
Sorour, a 41-year-old translator working at an official office in Tehran, faced a similar sequence. After her SIM card was disconnected, she was summoned to a location controlled by the same intelligence organization and interrogated for hours about her Instagram and X activity. She was ordered to make her accounts private and to pledge that she would not advocate for political prisoners, protest executions, or support demonstrators—a reference to the nationwide anti-government protests that erupted in late December 2025. Mina, 63, living in Isfahan, was blocked after she posted a comment supporting a particular political current under a foreign news outlet's post. When she refused to comply with a summons, both her SIM card and national identification card were deactivated. The consequences rippled through her life: she could not transfer money, access government systems, make online purchases, or use services requiring electronic identity verification. She was also locked out of Sana, the judiciary's electronic system, leaving her unable to determine whether charges had been filed against her or what legal proceedings, if any, were underway.
The pattern extends beyond these three cases. Zia Nabavi, a former political prisoner, posted on Instagram that his SIM card had been suddenly disconnected—he discovered it while at a doctor's office, where he needed his phone to access banking information. Reyhaneh Saeedi, a physician and activist, reported that her SIM card had been blocked for months, and this was the second time it had happened. The blockade has effectively prevented her from practicing medicine, issuing prescriptions, and renewing her licenses with the Medical Council. Her identification card was also deactivated. She received no formal ruling, no notification of charges, and no explanation despite her attempts to find out why. Actress Shaghayegh Dehghan also reported her SIM card blocked, with no clarity about which authority had done it or why.
What makes these disconnections particularly potent is the architecture of Iranian digital life. A SIM card is not optional infrastructure—it is the foundation upon which access to banking, judicial systems, administrative services, and insurance all rest. Blocking it does not merely prevent someone from calling a friend. It severs them from the systems required to live and work. The Defending Free Flow of Information organization documented in 2025 that journalists and activists had their SIM cards blocked without judicial orders, highlighting a critical absence: there is no clear mechanism for accountability, no transparent process, no formal charges, and no avenue for those affected to challenge the restrictions or even learn the reason they were imposed. The measure operates in a legal gray zone, wielded by security institutions with powers that appear to exceed any formal judicial oversight. For those targeted, the message is unmistakable: compliance or isolation.
