5G Vietnam has arrived in every province and is changing what phones and factories can do

5G Vietnam launched commercially on 15 October 2024, when Viettel switched on the country’s first commercial 5G service in every province and city at once. For a country that had lagged behind the world on 2G, 3G and 4G, the timing was a deliberate statement: this time, Vietnam would not wait. Within fourteen months, according to the Ministry of Science and Technology, commercial 5G coverage reached 91.2 percent of the population, one of the fastest rollouts anywhere. But the more interesting question is not how fast the signal spread. It is what the signal actually changes — for a person with a phone, for a factory, and for a country trying to run more of its life online.

The launch that covered the whole map at once

Viettel, the military-owned telecom group, began its 5G trials in 2019 and spent years testing the technology on a standalone 5G network before the commercial launch. On launch day it said it had installed 6,500 base stations across all 63 provinces and cities, offering speeds of up to 1 gigabit per second — roughly ten times the speed of 4G — with subscription plans starting at 135,000 dong a month, about 5.40 US dollars. Customers with 5G-capable phones could subscribe without changing their SIM cards.

The launch was also a matter of national pride. Viettel’s chairman noted that Vietnam is among a small group of countries able to produce its own 5G equipment. Behind the launch lay a year of spectrum auctions: Viettel won the B1 band (2,500–2,600 MHz) in April 2024, VNPT won the C2 band (3,700–3,800 MHz), and MobiFone won the 3,800–3,900 MHz band in July 2024. VNPT followed with its own 5G service on 10 December 2024, and MobiFone entered the market on 23 June 2025, focusing at first on major urban centres. The Politburo’s Resolution 57 on science, technology, innovation and national digital transformation, adopted in late 2024, gave the whole effort political backing, and Vietnamese companies are already turning their attention to 6G research.

Where the signal actually reaches

Coverage on paper and coverage in daily life are different things. At launch, Viettel’s 5G covered the downtown areas of all provinces and major cities, along with industrial parks, tourist areas, seaports, airports, hospitals and universities. That pattern — city centres and economic hotspots first — is how every country rolls out a new mobile generation, because that is where the users and the paying customers are.

What made Vietnam’s rollout unusual was its speed in reaching beyond those hotspots. By December 2025, the Ministry of Science and Technology reported 91.2 percent population coverage, which puts Vietnam among the world’s fastest countries in 5G deployment. Rural coverage is still thinner than urban coverage, and indoor signal in concrete buildings remains a weak point, as it is everywhere. But the direction is clear: 5G in Vietnam is not a showcase for two cities but a national network, and the gap between city and countryside is narrowing faster than it did for 4G.

What changes for people with a phone

For most phone users, the honest answer is that 5G changes less, at first, than the advertisements suggest. A 4G connection already handles messaging, video streaming and social media well. What 5G adds is headroom: downloads that finish in seconds, video calls that stay sharp on a moving bus, and a connection that does not slow to a crawl when ten thousand people in a stadium or a festival crowd all use their phones at once. Low latency — the delay between tapping and response, roughly one fifth of 4G — makes cloud gaming and augmented reality feel responsive rather than laggy.

The catch is that users need a 5G-capable phone and a 5G plan, and many Vietnamese are still on older handsets. Adoption follows the phone replacement cycle, which takes years. Operators priced entry-level 5G plans close to 4G prices, because the network is ready before most of the phones are, and adoption will follow the handset replacement cycle. As QR payments showed, Vietnamese consumers adopt new digital habits quickly once the price and the convenience line up.

What changes inside factories and ports

The more important story is not the phone in your pocket but the machines that never had a phone at all. 5G was designed for three things that 4G does poorly: connecting a huge number of devices in a small area, carrying data with very low delay, and keeping that connection reliable enough for machines to trust it. Those traits matter in factories, ports and hospitals far more than they matter to someone watching videos.

Viettel says it has developed 130 usage scenarios for corporate customers, spanning cloud, artificial intelligence and internet-of-things applications. In practice that means automated guided vehicles moving parts around a factory floor, cameras inspecting products for defects and sending the video to an AI system in real time, and sensors on port cranes reporting their status continuously. Remote surgery and self-driving vehicles are the examples that make headlines, but the near-term value is more ordinary: fewer cables on the factory floor, faster fault detection, and production lines that can be rearranged without rewiring the building. Industry forecasts put 5G-related revenue for Vietnamese operators at 1.5 billion US dollars by 2030, and the Ministry of Industry and Trade has estimated that 5G could contribute 7.3 to 7.4 percent of GDP growth in 2025.

Why 5G is only the start

The network still has to prove itself in the ways that matter. Operators need to fill in the gaps between city centres, bring 5G indoors, and build the standalone 5G core networks that deliver the lowest latency — the non-standalone networks most users connect to today are faster than 4G, but they do not unlock the full set of industrial uses. Businesses also need time to learn how to use the technology, and 5G base stations consume more power than 4G ones, so operators are looking for energy-efficient designs as they expand.

There is also the question of what comes next. Vietnam’s push into 6G research, involving Viettel, FPT and VNG, is about making sure the country is not only a fast follower but an early participant in the next generation. The pattern is familiar from the way Estonia built its digital government: infrastructure first, then services on top of it, then the habits that make the infrastructure indispensable.

What this means

5G in Vietnam is best understood as infrastructure that arrived ahead of demand. The signal reached 91.2 percent of the population in just over a year, but most of what it enables — smart factories, remote services, dense sensor networks — will take years to build. For phone users the change is gradual: faster downloads, better connections in crowds, and new services that appear as handsets catch up. For industry the change is structural, because a reliable, low-delay wireless connection lets factories and ports reorganise around data instead of cables. Vietnam launched 5G late by a few years and then caught up fast. The test now is whether the businesses, hospitals and schools that the network was built for will use it as boldly as the operators built it.
