Regulatory Framework for SMS in Hong Kong
The telecommunications and data protection landscape in Hong Kong is regulated by OFCA (Office of the Communications Authority). Compliance with local A2P SMS regulations is not optional — non-compliant traffic is actively filtered at the carrier level and can result in route blocks, financial penalties, and reputational damage.
Hong Kong’s PDPO (Personal Data (Privacy) Ordinance) governs marketing communications. Opt-out mechanisms are required. Spam regulations under the Unsolicited Electronic Messages Ordinance apply.
SBS Telecom’s Compliance & Regulatory Affairs team continuously monitors regulatory changes in Hong Kong and all markets we serve. Our clients benefit from proactive compliance guidance at no additional charge.
