Police Raid Taiwan-Linked SIM Box Scam Hubs in Bangkok Condos

Police have raided two condominium units in Bangkok and seized eight SIM box devices linked to a Taiwan-backed call centre scam network that rotated operations for just one hour a day to evade detection. The operation, led by the Anti-Online Scam Centre (ACSC) and Crime Suppression Division officers, targeted units in Huai Khwang and Wang Thonglang districts on 2 April at around 14:30. Authorities said the equipment was used to defraud victims.

The raids followed earlier action on 30 March, when officers searched an apartment in Hat Yai, Songkhla and confiscated five SIM box devices along with routers, backup power units, LAN cables and a CCTV camera. Investigators expanded their probe and discovered the same network had rented additional properties in Bangkok to continue operations. Search warrants issued by the Criminal Court led to the latest seizures at Asher Ratchada condominium in Soi 20 Mithuna and Chewathai Hall Ladprao Chokchai 4.

At the Bangkok locations, officers found air conditioning running continuously in unoccupied rooms, indicating remote operations. Each room contained four SIM box machines, with each device capable of holding 32 SIM cards, alongside routers, CCTV cameras, power strips and backup power supplies. The equipment had reportedly been installed for only three to four days before the raids.

Landlords told police that the rooms had been rented about a month earlier for 11,000 baht per month, with three months paid in advance. Investigators identified a Taiwanese national, named as Ah Yong, as the alleged financier behind the network. He is believed to have hired Thai nationals to rent multiple properties nationwide and rotate SIM box usage between locations to avoid law enforcement scrutiny.

Police said the group deliberately operated each site for around one hour per day, switching locations frequently to make detection more difficult. Authorities are now gathering further evidence to seek arrest warrants for those involved. The seized equipment is expected to provide key forensic data to support the investigation.

The crackdown reflects ongoing efforts by Thai authorities to combat online fraud networks that use SIM box technology to mask call origins and scam victims. Officials warn that such operations are increasingly sophisticated and mobile, requiring coordinated enforcement across multiple regions.

Thaitabloid reported that Investigators will continue to trace financial links and identify additional locations tied to the network. Arrests are expected as authorities move to locate the suspects and dismantle the wider operation.
