Iran's Islamic Revolutionary Guard Corps intelligence arm has operationalized SIM card disconnection as a coercion tool that reaches far beyond silencing phone calls. Because Iran's digital infrastructure routes banking, healthcare, judicial access, prescription services, and government administration through mobile-number-verified identity, killing a SIM card effectively unpersons the target. The IRGC-IO is exploiting a design choice — centralizing digital identity through a single telecom credential — as a pressure point against dissent. The mechanism is straightforward and extrajudicial. A citizen posts critical content or supports a political current online. Their SIM card is disconnected without warning or legal process. When they seek reconnection, they are summoned to an IRGC-IO location, interrogated for hours, and offered a deal: sign a remorse pledge, delete critical posts, publish pro-regime content, or remain digitally amputated. No court order is issued. No charges are filed. No formal legal channel exists to challenge the restriction. The cases documented by DW illustrate the breadth of targets. A 25-year-old university student named Sina was interrogated for six hours, had his phone confiscated, and a month later still had no SIM card or access to his social media. His Instagram was wiped and replaced with a single post declaring compliance. A 41-year-old translator named Sorour was ordered to make her account private and pledge to stop advocating for political prisoners. A 63-year-old woman named Mina in Isfahan had both her SIM and national identification card blocked after refusing an IRGC-IO summons, cutting her off from bank transfers, online purchases, and the judiciary's electronic system entirely. The tool has expanded to prominent figures. Former political prisoner Zia Nabavi reported his SIM was suddenly disconnected while at a doctor's office. Physician and activist Reyhaneh Saeedi said the block — her second — has prevented her from practicing medicine, issuing prescriptions, or renewing professional licenses. Her identification card was also deactivated. Actress Shaghayegh Dehghan reported a SIM block without knowing which authority ordered it. None received formal notice of charges or proceedings. The Defending Free Flow of Information (DeFFI) organization confirmed in 2025 that journalists and activists had their SIM cards blocked without judicial orders, establishing this as systematic rather than anecdotal. The architecture of the abuse is important: Iran built a system where a single credential — the SIM-linked mobile number — gates access to virtually all civic and economic participation. Security services then claimed unilateral authority to revoke that credential, creating a kill switch over citizens' ability to function in modern society. This is not internet censorship in the traditional sense. It is the construction of a conditional citizenship regime, where access to banking, healthcare, law, and commerce is granted or revoked based on political obedience. The absence of any accountability mechanism — no court, no charge, no appeals process — means the cost of dissent is functionally unlimited and entirely at the discretion of intelligence operatives. The pattern has been building for years. Iran cut internet access during the 2019 and 2022 protest waves. The SIM card weapon is the refined, individualized successor: instead of blacking out the whole country (which draws international attention), the regime can quietly disable individual citizens one by one, with no visible disruption to overall service. The protests that began in late December 2025 appear to have triggered a new wave of this targeted digital coercion.
