The Exclusive “Black Box” Story: Transitioning to an Open Ecosystem
Historically, telecom operators relied on foreign vendors for full-stack solutions to deploy their networks. While this approach ensured rapid implementation, it fostered dependency, limiting cost optimization, upgrade flexibility, and customization to meet Vietnam’s market demands and operators’ unique needs.
With the advent of 5G, Viettel made a strategic shift to a Cloud Native architecture, taking full control of its Telco Cloud development. This move enables Viettel to virtualize its network infrastructure on standard physical servers. Core mobile services (voice, data, SMS) now operate seamlessly on a cloud platform designed, built, and mastered entirely by Viettel’s team.
By mid-2025, Viettel’s lab successfully piloted a miniaturized 5G network ecosystem on its “Make in Vietnam” Telco Cloud. The integration of the 5G Core module into this infrastructure marked a significant milestone. The platform’s technological maturity has also attracted global tech giants like Ericsson and Nokia to collaborate, testing their core network applications on Viettel’s cloud. This new model shifts foreign vendors’ roles from full-stack providers to hardware suppliers operating on Viettel’s infrastructure.
Viettel engineers deploy, install, and operate 5G base stations, showcasing mastery over next-gen telecom infrastructure.
Viettel’s Telco Cloud ambitions gained momentum through elevated memberships in leading global tech organizations like OpenInfra Foundation (OIF), Cloud Native Computing Foundation (CNCF), and Linux Foundation (LF). Achieving Platinum status at OIF and Gold at CNCF grants Viettel engineers early access to cutting-edge technologies before global release, further solidifying their expertise.
This transition to a Viettel-led Telco Cloud enhances national security and user experience. By controlling core technologies, Viettel eliminates “Vendor Lock-in” risks, ensuring network and customer data security from the ground up. With a clear roadmap, Viettel is steadily realizing its vision of a “Made by Viettel” telecom infrastructure. Combining Telco Cloud autonomy with leadership in international open-source communities positions Viettel not just as a service provider, but as a foundational technology innovator.
Vietnam’s National Carrier Offers Exclusive 5G and Device Upgrade Deals
In early December 2025, Viettel announced the deployment of over 20,000 new 5G base stations, surpassing its government commitment by three weeks. By year-end, Viettel’s total 5G stations are expected to reach 30,000, covering 90% of Vietnam’s outdoor areas. Notably, Viettel is the only Vietnamese company to deploy a 5G SA (Standalone) network, a complete 5G architecture enabling theoretical speeds up to 10Gbps—15-20 times faster than 4G in real-world conditions.
The Ministry of Science and Technology certifies Viettel’s nationwide deployment of over 20,700 5G base stations.
Viettel’s 5G infrastructure has been officially certified by state authorities for meeting stringent quality and technical standards. All 20,700+ stations ensure stable, secure operations for users nationwide.
Over 2,000 new “Make in Vietnam” 5G stations comply with O-RAN standards, reflecting Viettel’s commitment to an open, flexible, and globally compatible network infrastructure.
