In an investigation into illegal SIM box centers used to convert international calls and internet-based communications into local calls using telecom connections, Karnataka police have discovered two more centers in Tamil Nadu’s Tiruchirappalli and Thanjavur districts. Police seized 10 SIM box devices with e-SIM capability from there.
A SIM box is a device used to fit multiple SIM cards into a single unit and divert telephone calls through internet-based technology.
Using such devices outside the regular framework of legally licensed telecommunications companies, it is possible to engage in activities such as concealing the true source of calls, converting international calls into local calls, and communicating through fake numbers. As a result, there is a risk that they may be used for telecommunications violations, online fraud, and crimes.
However, using SIM box devices alone is not a crime; the legal issue arises when they are used without proper authorization or for illegal purposes. In this context, cyber command unit police are continuing their investigation into the illegal SIM box network linked to the case registered at the Whitefield police station in Bengaluru.
At the beginning of this investigation, police identified two locations in Bengaluru’s Kadugodi and Pattandur Agrahara areas where SIM box devices were being operated. A total of 10 SIM box devices were seized from there.
The police examined the seized devices, telecommunications records, and related digital evidence. An investigation was conducted to determine whether these activities were confined to Bengaluru or had expanded to other areas.
Based on the information obtained in this review, traces were found indicating similar activities in Tiruchi and Thanjavur districts of Tamil Nadu. The relevant information was shared with the telecommunications department.
Following this, a field investigation carried out with coordination among various departments uncovered two more illegal SIM box centers in the two districts of Tamil Nadu.
It has been stated in a release issued by the Cyber Command unit of the Bengaluru City Police that 10 more SIM box devices with eSIM capability were seized from there. Police said the aim of the investigation is to identify the complete operational chain of this network.
The investigation is under way into where the SIM box devices were purchased from, how they were installed in various locations, how SIM cards and eSIM profiles were used, and what telecommunications infrastructure was involved.
Moreover, action has been taken to identify who coordinated or controlled these activities and who assisted them.
Investigations are also under way into the links between the centers discovered in Bengaluru and Tamil Nadu, those directing the operations from abroad, and local aides. Police are also examining whether there are other related locations and structures.
