The National Broadcasting and Telecommunications Commission (NBTC) has adopted a cap: cutting down SIM card ownership to no more than five mobile numbers per individual for all mobile operators. The rules are part of a wider effort to eliminate “ghost SIMs” and SIM box systems that are often exploited by fraud rings, which are especially rampant along Thailand’s border regions. The ministry also ordered tighter controls on SIM registration. All registrations carried out by authorised distributors must use Dip Chip identity verification or an equivalent secure digital platform, and users in identified high‑risk areas will face enhanced monitoring to prevent misuse.
