Bangkok: The NBTC is tightening control over SIM boxes and gateways to prevent call center gangs. Those who possess SIM boxes containing four or more SIM cards must apply for a license. Those found guilty face up to five years in prison.
According to Thai News Agency, Mr. Trirat Viriyasirikul, Deputy Secretary-General and Acting Secretary-General of the NBTC, announced that the Royal Gazette has published the NBTC's directive concerning radiocommunication equipment and stations exempted from licensing under the Radiocommunications Act B.E. 2498 (1955) (No. 3), set to take effect on October 23, 2025. The announcement mandates individuals possessing SIM boxes or gateway devices with four or more SIM cards prior to the effective date to apply for a relevant license from the NBTC office within 90 days. Non-compliance will result in imprisonment of up to five years, fines up to 100,000 baht, or both.
Mr. Trirat highlighted that the NBTC had previously issued an announcement regarding measures to combat technological crimes for telecommunications licensees, effective from August 30, 2025. This announcement includes eight measures aimed at protecting the public and preventing damage from technological crimes, aligning with directives from the Technology Crime Suppression Commission, chaired by the Prime Minister.
The NBTC's new measures also prohibit telecommunication service providers from allowing unregistered SIM box devices to connect to their networks, emphasizing the shared responsibility under Section 4/1 for compliance.
