Vietnam is gearing up for a pivotal moment in its telecommunications landscape, re-launching the auction of two crucial frequency bands in the 700 MHz spectrum. This re-auction follows an earlier attempt that did not meet expectations, indicating a renewed urgency to boost 4G and 5G mobile services in the nation. The Ministry of Science and Technology has announced that the B1-B1’ (703–713 MHz/758–768 MHz) and B3-B3’ (723–733 MHz/778–788 MHz) bands are now available for bidding, starting at over VND 1.95 trillion (approximately USD 75 million). Licenses will grant operators rights for a period of 15 years.
This auction is more than just numbers on a spreadsheet; it serves as a crucial step in enhancing mobile network coverage, particularly in rural and underserved regions of Vietnam. The 700 MHz spectrum is internationally recognized for its long-range and high-penetration capabilities, making it an ideal candidate for improving service quality, not just in bustling urban centers but also in remote areas where connectivity can feel like a pipe dream.
Interestingly, state-run Viettel Group, which snagged the B2-B2’ band in May 2025 in a spirited two-round bidding session, will sit this one out. That prior victory, which also spans 15 years, forms part of Viettel’s strategy to bolster nationwide 4G and 5G connectivity, essential for pioneering initiatives like smart cities and intelligent agricultural systems that could make even farmers do a double-take.
Operators interested in tapping into this new wave of opportunity have 30 days from the official auction notice to validate their eligibility. This strategic reallocation of the 700 MHz band comes on the heels of Vietnam’s switch from analog to digital TV broadcasting, unlocking valuable spectrum for the mobile telecommunications sector.
As of January 2025, Viettel reported hitting a remarkable milestone of 4 million 5G subscribers in a mere few months after launching its service in October 2024. The telecommunications giant’s 5G network, supported by around 6,500 base stations, boasts impressive speeds of up to 1 Gbps and near-zero latency. With ambitious plans to install over 20,000 additional 5G stations by the close of 2025, Viettel aims to provide comprehensive coverage to 99% of the population by 2030.
In tandem with its ambitious rollout, Viettel has established two dedicated 5G labs in Hanoi and Ho Chi Minh City. These innovation hubs allow developers to experiment with new 5G and Internet of Things (IoT) technologies tailored for local applications. The telco’s infrastructure supports both standalone (SA) and non-standalone (NSA) architectures, covering a stunning array of over 130 use cases across various sectors, including logistics, healthcare, and energy.
Viettel isn’t alone in this race; competitors such as VNPT and MobiFone have also stepped into the 5G arena. VNPT launched its 5G services in December 2024, followed by MobiFone in March 2025, utilizing the 3.8–3.9 GHz frequency band. Both operators are deploying a mix of NSA and SA 5G models, ensuring that the competition remains fierce and consumers stand to benefit.
As Vietnam prepares for the renewed 700 MHz auction, industry insiders anticipate a wave of interest from operators eager to broaden their mobile reach and upgrade the nation’s digital infrastructure. The stakes are high, but so are the rewards — a vibrant, connected future awaits just around the corner.
What significance does the 700 MHz spectrum hold for Vietnam’s mobile services?
The 700 MHz spectrum is essential for enhancing mobile network coverage, particularly in rural areas, as it offers long-range and high-penetration capabilities that improve service quality.
Why is Viettel Group not participating in the upcoming auction?
Viettel Group, which previously secured the B2-B2’ band, is ineligible to bid in this auction, allowing other operators a chance to expand their networks.
How is Viettel planning to expand its 5G infrastructure?
Viettel aims to install over 20,000 additional 5G base stations by the end of 2025, with an ambitious goal of covering 99% of the population by 2030 following rapid subscriber growth.
