Chinese SIM alerts in Thailand

Travelers using Chinese mobile numbers in Thailand say they received automatic warning texts telling them not to engage in illegal activity overseas. (x.com) Posts showing the messages spread widely on X, with photos of the alert displayed on phones in Thailand. The wording in the screenshots says Chinese authorities are “reminding” users abroad to stay away from crimes including telecom fraud. (x.com) China’s Ministry of Public Security said on June 20, 2025 that the government had added a new “overseas call reminder” service, and the Ministry of Industry and Information Technology said telecom carriers rolled it out nationwide in March 2025. The notice says users now see alerts when they receive overseas calls or texts, including the originating country or region. (mps.gov.cn) The same public security notice tied the service to China’s anti-fraud campaign, which also includes the 12381 warning text system and the 96110 anti-scam hotline. The ministry said the 12381 system had sent 1.388 billion warning messages since its 2021 launch. (mps.gov.cn) Thailand sits at the center of that campaign because Chinese officials have spent the past two years pressing neighbors to help shut down scam compounds in Myanmar, Cambodia and Laos. China’s State Council Information Office said in July 2025 that joint operations with Thailand, Myanmar and Cambodia had dismantled more than 2,000 overseas scam dens and led to more than 80,000 arrests. (english.scio.gov.cn) The issue hit Thailand’s tourism industry directly in January 2025, when Chinese actor Wang Xing was rescued after being trafficked across the Thai-Myanmar border into a scam operation. Reuters reported on January 27, 2025 that the case pushed Thai and Chinese authorities to widen their crackdown. (voanews.com) Thailand then cut electricity, fuel and internet service to some Myanmar border areas in February 2025 as part of that response. Reuters reported the move reflected concern in Bangkok that scam centers were hurting confidence in Thai travel. (nst.com.my) Chinese officials and the Chinese embassy in Bangkok have also spent years pushing anti-fraud tools directly to citizens in Thailand. In June 2022, the embassy promoted the 12381 warning text system and the National Anti-Fraud Center application to Chinese nationals in Thailand. (china-embassy.gov.cn) That makes the Thailand screenshots look less like a one-off glitch than a visible example of China’s broader practice of extending telecom fraud warnings beyond its borders. The posts do not show a formal Thai government role in sending the texts, and the available evidence points instead to alerts tied to Chinese carriers and Chinese anti-fraud systems. (x.com)
