LUCKNOW, Nov. 3 -- A suspected China link has emerged in the illegal SIM box network busted by the Lucknow Police; all six seized devices bearing 'Made in China' markings. Investigators are now tracing how the 32-port equipment entered India, who supplied it and whether it was used to facilitate cyber frauds across the country. Police said the seized 32-port devices were being examined under the Telecommunications (Radio Equipment Possession Authorisation) Rules, 2026, which prescribe regulatory requirements and authorisation for equipment capable of accommodating more than four SIM cards. Investigators are probing whether the devices were brought into India disguised as sound amplifiers and identifying those involved in their supply and distribution, said Kiran Yadav, ADCP (Crime). The findings come a day after the Crime Branch recovered six SIM boxes, routers, VPN gateways and other networking equipment from four different locations in Lucknow during Operation Digital Kavach on Sunday. A technical examination revealed that 192 e-SIMs were active in the setup. Police also recovered dismantled sound amplifier components, strengthening suspicion that the equipment may have been imported under their guise. Correspondence has been initiated with telecom companies to obtain technical details of the seized devices. Investigators found that the operators allegedly used Wi-Fi-connected video doorbells instead of conventional CCTV cameras at the premises to monitor visitors and movement. The police are examining whether the devices were used in cyber frauds reported elsewhere in the country. Their IMEI numbers and other technical identifiers are being matched with complaints registered on the National Cyber Crime Reporting Portal. Details are also being shared with the Indian Cyber Crime Coordination Centre for nationwide verification. A SIM box routes internet-based calls through local mobile networks, allowing callers operating from abroad to make calls appear as though they originate from Indian mobile numbers. The technology can be misused in digital arrest scams, investment frauds and other impersonation-based cybercrimes. However, police said no specific organisational or foreign network link had been established so far....
