Malaysia Builds Momentum in 5G and Mobile Growth

Malaysia has a robust telecommunications infrastructure and a competitive mobile market. According to GSMA Intelligence, Malaysia had 43.3 million cellular mobile connections at the start of 2025. It is important to note that many individuals use more than one mobile connection, such as one for personal use and another for work, so the total number of mobile connections often exceeds the population. The growing adoption of eSIMs has further simplified the use of multiple connections on a single device.

In fact, GSMA Intelligence data shows that, as of January 2025, mobile connections in Malaysia were equivalent to 121% of the country’s total population.

Looking at recent trends, mobile connections grew by 474,000, an increase of 1.1%, between the start of 2024 and early 2025. Additionally, 99.0% of mobile connections in Malaysia are now classified as broadband, meaning they connect through 3G, 4G, or 5G networks.

However, it is worth noting that not all devices on broadband-capable networks actively use mobile data. Some connections may be limited to voice and SMS services only, so this broadband percentage should not be interpreted as a direct indicator of mobile internet usage.

As part of its broader economic development efforts, Malaysia has actively promoted open competition in the telecommunications sector. This approach has led to high penetration rates in both mobile and mobile broadband services, along with near-universal LTE coverage. Since the launch of 5G in 2022, adoption has grown rapidly, with 5G making up 38 % of all mobile broadband subscriptions by September 2024.

The major mobile operators in Malaysia are CelcomDigi, Maxis, U Mobile, YTL Communications (YES), and Unifi Mobile. These operators have been actively involved in the rollout of Malaysia's national 5G network and are key players in the country's telecommunications landscape. 

To maintain consistent 5G service quality, Malaysia’s mobile operators continue to utilise the state-owned 5G network operated by Digital Nasional Berhad (DNB). In May 2023, Malaysian authorities announced plans to transition to a dual 5G network model once DNB reached 80% population coverage, a milestone that was achieved in December 2023.

This shift marked a significant policy change, including the revocation of a 2021 ministerial directive that had previously appointed DNB as the sole entity responsible for Malaysia’s 5G rollout.

DNB was established by the government in 2021 as a special-purpose vehicle tasked with developing the national 5G infrastructure. Its network, deployed by Ericsson, is currently used by private telcos to deliver 5G services to consumers and businesses.

As of now, the major mobile operators in Malaysia provide 5G services through DNB’s state-run network. These include CelcomDigi, Maxis, YTL Communications (Yes 5G), and U Mobile. Each of these operators, except for Telekom Malaysia which had its equity deal cancelled, holds a 16.3% equity stake in DNB. The Ministry of Finance retains a 34% share.

CelcomDigi holds a 30.1% market share in the Malaysian telecommunications sector. This is a significant increase from 2023, following the merger between Celcom and Digi in November 2022. The merged entity has become the largest telecommunications company in Malaysia, surpassing its closest rival, Maxis.

Currently, it serves over 20 million customers, two-thirds of the Malaysian population, through 6.7 million postpaid and 13.4 million prepaid subscribers. CelcomDigi operates the widest 4G network, covering over 96 % of the population nationwide from approximately 24,000 network sites and has an extensive fibre network of around 15,000 kilometres.

CelcomDigi and Ericsson have signed a Memorandum of Understanding to introduce AI-driven network analytics across CelcomDigi’s infrastructure, aiming to enhance operational efficiency as 5G adoption continues to rise in Malaysia. As part of the agreement, both companies will collaborate on the development of intent-based autonomous networks, integrating AI and automation to improve network performance and efficiency. They also plan to explore the use of AI in building advanced 5G service assurance solutions, with the goal of delivering more reliable and tailored connectivity experiences for both businesses and consumers.

According to Ericsson, Malaysia registered 18.2 million 5G subscriptions as of the end of 2024, which equates to a market penetration rate of 53.4%.

CelcomDigi also signed a Memorandum of Understanding with ZTE to collaborate on integrating AI technologies into its telecommunications infrastructure. The companies plan to explore AI-driven solutions such as new calling, intelligent deep packet inspection for smarter network traffic management, and intelligent operations and maintenance to automate network monitoring and maintenance using AI-powered predictive analytics.

Maxis is the second largest operator in Malaysia. Maxis operates one of the most reliable 4G LTE networks in the country, reaching over 95% of the population. With Malaysia's ongoing 5G rollout under the DNB single wholesale network model, Maxis was initially cautious in adopting the new structure. However, in 2023, Maxis signed an access agreement with DNB, enabling it to begin offering 5G services.

According to Opensignal, Maxis was the first Malaysian operator to win the Reliability Experience award. It also won the Consistent Quality award with 67.3% of tests, closely followed by Digi with 67.1%. Since the last report, Maxis’ Consistent Quality score has improved by 11 percentage points.

U Mobile, despite being a smaller operator, has announced plans to build Malaysia's second 5G network, aiming to rival the first built by DNB. The decision follows government approval for a second 5G network in a move to end the monopoly previously held by DNB. U Mobile has chosen Chinese vendors Huawei and ZTE as technology partners for this project.

The enterprise-grade 5G network will support 5G Advanced and network slicing from day one, enabling tailored services for industries like healthcare, transport, and smart cities. U Mobile’s rollout emphasises improved indoor 5G coverage and prioritises key locations such as transport hubs, medical centres and data centres. U Mobile has stated it will continue working with DNB to ensure quality of service during the transition.

Unifi Mobile is a Malaysian internet mobile network operator and a subsidiary of the national telephone company, Telekom Malaysia. Unifi performed well in the recent Opensignal report, winning the 5G Download Speed Award with speeds of 290.3 Mbps. In the previous report, there had been a three-way tie but Unifi has now emerged as the sole winner. Unifi also won the 5G Video Experience Award with a score of 77.7 on a 100-point scale, more than two points higher than Digi.

Yes Mobile is operated by YTL Communications Sdn. Bhd., a subsidiary of YTL Corporation Berhad, a leading Malaysian infrastructure conglomerate. Launched in November 2010, Yes Mobile was the fifth mobile operator in Malaysia and distinguished itself by deploying an all-IP, all-4G network from the outset.

In December 2021, Yes Mobile became the first operator in Malaysia to launch 5G services, branded as Yes FT5G. This rollout was facilitated through a partnership with DNB. Yes Mobile's 5G services initially covered areas such as Kuala Lumpur, Putrajaya, and Cyberjaya.

The Yes network is built with an all-IP architecture, making it the first and only all-4G and all-IP network provider in Malaysia capable of offering unique services such as user ID-based unified communications and session concurrency for mobile data and telephony services. Yes operates its own network infrastructure in Malaysia, with close to 5,000 base stations and an all-4G network footprint reaching over 85% of the population.

As Malaysia continues to expand its 5G infrastructure, mobile operators are in active competition and are poised to integrate next-generation technologies into their offerings.

How O2 Telefónica is Redefining the Network with NaaS and Open APIs

At O2 Telefónica Germany, the “network of the future” is no longer a distant vision, it’s becoming an operational reality. Under the leadership of Matthias Sauder, Director Networks, the operator has made substantial strides in transforming its end-to-end infrastructure to meet the demands of a highly agile, programmable, and customer-focused future.

At the FutureNet World conference in London (7–8 May 2025), where leading telco and tech stakeholders gathered to explore network automation and AI in telecoms, Sauder shared how O2 Telefónica’s evolution journey spans radio, transport, core, data centres, and cloud landing zones, all underpinned by a strategy that prioritises automation, flexibility, and openness.

The transformation began with a foundational goal: enhancing radio network quality. Once considered the underdog in a three-operator market, O2 Germany set out to radically improve performance by embracing agile practices and reshaping internal structures. Inspired by the Spotify model, the company introduced agility not just in project management but also in technical delivery. This included frequent software release cycles for radio, positioning itself as a global leader in rapid deployment and continuous integration.

A key initiative known as Tech Strategy 25 laid the foundation for modernising radio, transport, and core networks. Today, over 80 percent of the strategy has already been executed. With a largely cloud-native core in place, O2 Telefónica is among the pioneers of this architectural shift. Its collaboration with Ericsson produced one of the world’s first cloud-native digital cores, while a parallel effort with Nokia deployed core services for one million users in a public cloud environment.

The rationale behind both cloud-native and public cloud approaches is clear. Legacy architectures no longer support the operational agility or cost efficiency needed in today’s competitive telecom landscape. Cloud-native systems enable advanced capabilities such as continuous integration, continuous delivery, and seamless in-service software upgrades (ISSU). O2 Telefónica has shown these upgrades can be executed without disrupting live customer services, challenging the long-standing perception that such practices are too risky for telco-grade reliability.

Beyond infrastructure, the company’s future network model hinges on the integration of open APIs and Network-as-a-Service (NaaS) capabilities. These aren’t abstract concepts, they’re practical tools enabling agility, programmability, and new revenue streams. Open APIs expose network functions to external developers and partners, unlocking opportunities for co-creation and monetisation that were previously out of reach.

This openness also extends to industry partnerships. A standout example is the company’s collaboration with Siemens, which now leverages O2's slicing capabilities to deliver tailored network services to its own customers. These kinds of arrangements demonstrate how NaaS, built on secure and standardised APIs, can unlock vertical-specific innovation.

But transformation isn’t just about technology, it’s also about mindset and culture. Simplifying and standardising network configurations (for example, reducing radio setups from over a hundred to just two) and promoting a service-centric approach are part of a broader shift. The focus is firmly on use cases and customer value, avoiding the trap of deploying technology for its own sake. Every new system or tool must demonstrate end-to-end value.

O2 Telefónica also recognises that data, rather than AI alone, is the foundation of intelligent automation. Without a robust data strategy, ambitions around AI, closed-loop automation, or service orchestration are unlikely to succeed. The company’s investment in OSS transformation and data-driven operations is laying the groundwork for intelligent networks that can scale, adapt, and optimise in real time.

As the line between network and IT continues to blur, O2 Telefónica is aligning its BSS, OSS, and IT systems with its network strategy. This integrated approach supports holistic innovation and positions the company to deliver services with faster time to market and greater cost efficiency.

The transformation journey shared by Matthias Sauder is more than a technical roadmap, it’s a call for industry-wide disruption. With revenues flat and operational costs rising, embracing NaaS, open APIs, and cloud-native infrastructure is no longer optional. It’s the only viable path for telcos to stay competitive, innovative, and relevant in a software-defined, platform-centric future.
