Cambodia’s 5G Rollout: Why 2,000 Base Stations in Six Months Is More Than a Headline

The Cambodia 5G rollout began simultaneously across all three operators on 1 January 2026. Between then and 8 June, they deployed 2,091 5G base stations across the country. The speed of this rollout surprised most observers. It should not have. Here is why it is happening, what is driving each operator’s strategy, and what the commercial picture actually looks like.

The Cambodia 5G Rollout Numbers, Verified

Cambodia’s 5G services launched simultaneously across all three major operators at midnight on 1 January 2026, a date set by the Ministry of Posts and Telecommunications (MPTC). Cambodia’s 5G rollout caught most regional telecom analysts off guard.

According to a Telecommunication Regulator of Cambodia (TRC) report dated 12 February 2026, 1,494 base stations had been deployed within the first six weeks: Smart Axiata leading with 674, Metfone at 531, and Cellcard at 289. By the time of a subsequent TRC report dated 8 June 2026, the total had reached 2,091 — Smart at 748, Cellcard at 742, and Metfone at 601.

The Cellcard figure deserves particular attention. The company went from third place at 289 sites in February to near-parity with Smart by June — more than doubling its footprint in roughly four months. Cellcard CEO has stated the company is targeting 1,000 sites by the end of July 2026, focused on dense urban and indoor deployments across shopping malls, ministries, hospitals, universities, hotels, and stadiums in Phnom Penh and the Central Region.

Smart Axiata deployed over 600 sites across 21 provinces within the first 27 days of launch. By Khmer New Year in April, it had reached 750 sites. CEO Ritesh Kumar Singh has committed to covering all 25 provinces by end-2026. The network currently delivers typical speeds of 100 to 200 Mbps, with more than 750,000 users connecting to it daily.

Metfone, operated by Viettel Cambodia, had the broadest initial geographic reach — covering all 25 provinces by February — consistent with its strategy of wide coverage from the outset rather than depth-first in Phnom Penh.

Why the Rollout Is Moving This Fast: Seven Reasons

The speed of Cambodia’s 5G deployment is not accidental. It reflects a specific combination of infrastructure conditions, regulatory positioning, competitive dynamics, and commercial incentives that converged at the start of 2026. Each of the following reasons is a genuine factor, not a narrative convenience.

1. Cambodia entered 2026 with strong 4G foundations

As of 2024, Cambodia had 13,498 antenna towers with 4G coverage reaching 93.2 percent of the population and 82 percent of the land area. This is the platform that 5G is being deployed on top of. The operators had existing field teams, site permissions, power infrastructure, and spectrum management experience. Deploying 5G radio on an already-prepared 4G site is substantially faster than building from scratch. Cambodia’s unusually strong 4G foundation for a frontier market — the result of a decade of sustained investment — compressed the 5G deployment timeline significantly.

2. Three simultaneous operators created immediate competitive pressure

Because all three operators launched on the same date under MPTC direction, none could afford a measured, phased rollout. The moment Smart deployed 600 sites in the first month, Metfone and Cellcard faced competitive pressure to match coverage claims. This simultaneous launch dynamic — unusual in regional telecom, where operators typically launch sequentially — created a deployment race that accelerated all three rollouts simultaneously.

3. Sub-6 GHz spectrum enables wide-area coverage without dense infrastructure

Cambodia is deploying 5G on the 3.5 GHz band (C-band), with 100 MHz of spectrum distributed by the MPTC. A 700 MHz auction for a coverage band was also planned for early 2026. Sub-6 GHz 5G — as opposed to mmWave — propagates more like 4G, meaning existing tower infrastructure can support meaningful coverage radius. Countries deploying 5G on mmWave bands (primarily the US) require far denser small-cell infrastructure. Cambodia’s mid-band approach means more territory covered per site, at lower additional capital cost per site.

4. Government mandate created regulatory urgency at the operator level

Prime Minister Hun Manet personally authorised the nationwide 5G system. MPTC Minister Chea Vandeth stated at the Digital Government Forum 2025 that Cambodia was “fully prepared” to launch 5G from January 2026. The Pentagonal Strategy Phase I (2023–2028) identifies digital economy development as a core national priority. This policy alignment meant operators faced genuine regulatory expectation — not just encouragement — to deploy at pace. The TRC has continued to publicly “encourage all operators to build additional 5G base stations” since launch.

5. Huawei ecosystem dominance across two of three operators

Smart Axiata and Metfone both use Huawei as their primary 5G equipment vendor — a relationship that predates the 5G launch and was formalised through partnership agreements from 2019 onwards. At MWC 2026, Smart and Huawei Cambodia signed an MOU specifically to advance 5G Fixed Wireless Access (FWA) business in Cambodia, with a focus on sub-5-minute installation and QR code activation. Huawei’s deployment toolkits, CPE ecosystem, and site optimisation software — refined across dozens of markets — are a genuine operational accelerant. When both the largest and third-largest operator are running the same vendor stack, deployment consistency and speed both improve.

6. Financial pre-positioning by the leading operator

In April 2025 — eight months before the 5G launch — Smart Axiata secured a USD 50 million financing facility from CIMB Bank Cambodia, specifically to upgrade network quality ahead of mass 5G adoption. This was not a reactive funding event; it was a strategic pre-positioning. Smart entered the 5G launch with capital already in hand and deployment logistics already planned. The financial readiness translated directly into deployment speed in January 2026.

7. No legacy fixed broadband infrastructure to protect

Cambodia never built a nationwide FTTH network. Most households that want broadband connectivity get it wirelessly. This means 5G Fixed Wireless Access (FWA) — home broadband delivered over 5G rather than fibre — is not competing with an entrenched fixed infrastructure investment. For Smart, FWA is described by CEO Ritesh Kumar Singh as “one of the most important pillars of Smart’s 5G strategy.” In markets with heavy FTTH investment, operators face an internal cannibalisation dilemma when pricing FWA. In Cambodia, that dilemma does not exist. The FWA commercial model is cleaner, and operators have more incentive to deploy 5G infrastructure quickly to capture the home broadband market.

The Commercial Picture: What Operators Are Actually Betting On

Understanding the deployment pace is one question. Understanding what commercial model operators are building toward is a different one — and more relevant for businesses making decisions about Cambodia as a market.

FWA as the first revenue path

Fixed Wireless Access is the most immediately monetisable 5G application in Cambodia. Smart’s FWA product, developed in partnership with Huawei, can be installed in under five minutes and activated via QR code. It runs on Wi-Fi 6, delivers stable high-speed performance for multiple devices, and is marketed to home users, small businesses, retail outlets, and multi-branch enterprises. In a market where FTTH penetration is low and mobile-first connectivity is the norm, 5G FWA is not a premium tier of home broadband — it is, for many users, the first reliable broadband they have accessed.

Enterprise: the growth segment

According to Mordor Intelligence’s Cambodia Telecom MNO market report, enterprise connectivity is projected to be the fastest-growing segment in Cambodia’s telecoms market between 2026 and 2031, at a CAGR of 5.02 percent — faster than the overall market CAGR of 4.33 percent. Consumer subscribers still account for 87.62 percent of revenue, but the growth trajectory is clearly toward enterprise.

In June 2026, Smart hosted its Smart Enterprise Forum in partnership with Huawei, China Telecom, AIonOS, Radware, and Axiata Cyber Fusion Center — bringing international technology partners together to demonstrate 5G and AI applications for Cambodian businesses. The forum’s positioning was explicit: 5G as an enabler of business efficiency, not just faster consumer internet. The enterprise verticals most frequently cited are manufacturing, logistics, fintech, and digital services.

The market size that frames the opportunity

Cambodia’s telecoms MNO market is valued at USD 681.2 million in 2025 and is forecast to reach USD 894.6 million by 2031. Data and internet services already account for 50.17 percent of revenue — a majority share, and one that will increase as 5G adoption grows. IoT and M2M services are a small contributor today but are forecast to grow at a 4.64 percent CAGR, slightly ahead of the overall market.

The 5-SIM-per-ID regulatory cap introduced by TRC is a structural driver of commercial change. It closes off the volume-of-subscribers growth model that characterised the 4G era — where operators competed on SIM acquisition — and forces a pivot toward revenue-per-customer, higher-value data plans, and B2B services. This regulatory shift is as commercially significant as the 5G technology itself.

The infrastructure context that most analysis misses

Cambodia’s 5G rollout is happening alongside two major infrastructure projects that will shape its commercial relevance over the next decade. The Funan Techo Canal — a USD 1.7 billion, 180-kilometre waterway connecting Phnom Penh to the Gulf of Thailand — will materially alter Cambodia’s logistics map and create new SEZ and industrial connectivity requirements. The Techo International Airport, a USD 1.5 billion project, will similarly create enterprise connectivity demand in its vicinity.

5G connectivity in Cambodia is not just a consumer story. It is part of the infrastructure stack that a country building toward upper-middle-income status by 2030 needs to have in place. The operators deploying today are pre-positioning for the enterprise and industrial connectivity demand that these projects will generate.

What This Means for Businesses Considering Cambodia

The honest read, for a business considering Cambodia as a market or operational base, is this:

• The connectivity infrastructure is materially better than the perception. Cambodia’s 4G coverage at 93.2 percent of the population, combined with 2,091 5G base stations deployed in six months, means that urban and semi-urban business operations can rely on mobile connectivity more than most external analyses suggest. The gap between perception and reality is a genuine competitive advantage for early movers.
• FWA as business broadband is a practical option today, not a future aspiration. Sub-five-minute installation, QR code activation, Wi-Fi 6 performance, and Smart’s commercial network makes 5G FWA a viable primary business broadband solution for SMEs operating in Phnom Penh and major provincial centres today. This is a meaningful change for businesses that struggled with FTTH availability or reliability.
• Enterprise 5G services are early stage but moving fast. The Smart Enterprise Forum in June 2026 signals that operators are building the B2B commercial capability, not just the network. The 5.02 percent CAGR on enterprise connectivity suggests this is not a speculative projection — it reflects real demand building in the market. Businesses in manufacturing, logistics, and digital services should be tracking this closely.
• The quality-versus-coverage gap is real and should be factored in. Royal Academy analyst Seun Sam’s point about 4G inconsistency applies to 5G as well. Outside Phnom Penh and provincial capitals, performance variability is real. A business making connectivity-dependent operational decisions needs to verify coverage and performance in their specific location, not assume uniform national performance.
• The commercial opportunity window is narrowing, not widening. Cambodia’s 5G deployment is moving faster than its commercial ecosystem. The businesses that build digital services, IoT applications, or enterprise connectivity solutions on top of this infrastructure now will have a meaningful head start over those that wait for the market to be “proven.” The infrastructure is ahead of the commercial adoption curve — which is exactly where early movers want to be.

The leapfrog dynamic I described in an earlier analysis — Cambodia skipping intermediate infrastructure stages and arriving directly at current-generation solutions — applies here with particular clarity. A country that went from limited 4G to 2,091 5G base stations in six months is not taking a cautious, measured approach to its digital infrastructure. It is moving with intent. The question for businesses is whether their commercial strategy is keeping pace.
