Vietnam’s Decree No. 163/2024/ND-CP (Decree 163), which has been in full effect since January 1, 2025, provides crucial guidance on the implementation of Vietnam’s 2023 Telecom Law. Decree 163 replaced Decree No. 25/2011/ND-CP dated April 6, 2011 (Decree 25), which guided the implementation of the previous 2009 Telecom Law, and introduces many notable changes to the regulations on telecom service provision. Some key changes that will impact businesses engaged in the telecom sector in Vietnam are detailed below. 1. Classification of Telecom Services The classification of telecom services into “basic telecom services” and “value-added telecom services” has been retained, in alignment with Vietnam’s WTO commitments in the telecom sector. However, Decree 163 expands the scope of both categories, as follows: Basic telecom services: “Transmission services for machine-to-machine (M2M) communication” and “leasing services of all or part of the telecom network” are added. “Image transmission services” is changed to “transmission services for radio and television.” Value-added telecom services: “Data center services,” “cloud computing services,” and “basic telecom services over the internet” (also known as over-the-top (OTT) telecom services) are added. 2. M2M Communication Services Since M2M communication services are classified as basic telecom services, without exception, they are subject to the same regulatory framework. Specifically: Cross-border provision: M2M communication services provided across borders must be conducted through a commercial agreement with a Vietnamese telecom enterprise licensed to provide telecom services with an international communication scope. Onshore provision: Onshore M2M communication services will require a telecom license. 3. New Telecom Services (Data Center, Cloud, and OTT Telecom Services) The 2023 Telecom Law adopted a light-touch management approach for data center, cloud, and OTT telecom services by not requiring the same licensing as previously regulated value-added telecom services, but instead mandating registration or notification before service provision. Decree 163 offers clearer guidance
