The company was created through the merger of two major telecom brands in Malaysia—Celcom and Digi. The merger between these two companies established CelcomDigi as a dominant mobile service provider that delivers 4G and 5G network services to over 20 million customers throughout the country.

CelcomDigi Merger Timeline

The merger created a larger telecommunications business, but network and technology integration continued after the legal completion of the merger. In 2023, CelcomDigi launched a large-scale programme to integrate and modernise its network across thousands of sites.

Why Did Celcom and Digi Merge?

The merger brought together two established telecommunications operations. The combined company could use the assets, expertise, technology, retail presence, and customer relationships of both businesses.

Network integration became an important part of the merger. CelcomDigi began modernising and combining its network infrastructure to improve coverage, capacity, and customer experience.

The company announced a large-scale network programme involving about 18,000 sites in 2023. The programme focused on integrating and modernising the existing 4G network with newer LTE and 5G-ready technologies.

Why CelcomDigi Is Important in Malaysia

CelcomDigi plays an important role in Malaysia’s telecommunications sector by providing mobile connectivity, internet services, and digital solutions. Its network helps people communicate, study, work, and access online services. Businesses also rely on reliable connectivity for daily operations, while stronger digital access supports Malaysia’s growing digital economy and technology adoption.

Advantages of Using CelcomDigi

Users select CelcomDigi due to comprehensive coverage, improved services, and plan diversity. The consolidation of Celcom and Digi has led to a stronger network infrastructure, enhancing speed and minimising drop-outs. 

Users enjoy affordable prepaid and postpaid plans, enhanced digital services with an app and self-service options, and personal and business-oriented services. These benefits make CelcomDigi a suitable option for customers seeking efficient and up-to-date telecommunication services.

What Services Does CelcomDigi Offer?

CelcomDigi provides telecommunications and digital services for different types of users.

Mobile Prepaid Plans

Prepaid services allow customers to purchase mobile connectivity without committing to a traditional monthly postpaid contract. Customers can use prepaid services for:

• Mobile data
• Calls
• SMS
• Internet passes
• 5G access where supported
• Short-term connectivity needs

Prepaid plans can suit users who want greater control over their monthly spending or prefer to purchase connectivity when needed.

Mobile Postpaid Plans

Postpaid services provide mobile connectivity through a recurring monthly plan. Depending on the package, customers may receive mobile data, calls, 5G access, device offers, and other benefits. Postpaid plans can suit customers who use mobile data regularly and prefer a predictable monthly billing arrangement.

4G and 5G Network Services

Mobile connectivity remains one of CelcomDigi’s core services. The company has invested in network integration and modernisation since the merger. Its network strategy covers 4G coverage and 5G-ready infrastructure, while the company continues expanding 5G services in Malaysia.

Network availability can vary by location, device, plan, indoor environment, and local network conditions. Customers should check coverage for their specific address before selecting a service.

CelcomDigi Home Fibre

CelcomDigi also provides home fibre broadband for customers who need a fixed internet connection. Home fibre can support activities such as:

• Video streaming
• Remote work
• Online learning
• Gaming
• Video calls
• Smart-home devices
• Multiple connected devices

The company has expanded its fibre services alongside its mobile offerings. Its earlier Home Fibre plans included speeds of up to 1Gbps.

International Roaming

Customers who travel outside Malaysia can use international roaming services where supported.

Roaming availability, pricing, data allowances, and partner networks depend on the destination and selected package. Travellers should check the current roaming options before leaving Malaysia.

Customer Support and Self-Service Features

CelcomDigi has contemporary customer support services that facilitate telecom service management. Customers can use apps to make payments, check data consumption, change plans, and more, all from their mobile devices. 

Web-based chats with customer support and store locators add to the convenience. These user-friendly tools increase efficiency and convenience, while empowering customers to manage their telecoms in a rapidly evolving digital ecosystem.

How Has CelcomDigi’s 5G Network Developed?

5G has become an important part of CelcomDigi’s network strategy. The company has continued expanding its 5G footprint while modernising its 4G infrastructure. In 2026, CelcomDigi announced the rollout of 5G services at Pavilion Kuala Lumpur, adding indoor 5G connectivity at a high-traffic commercial location.

5G can provide:

• Faster data speeds
• Lower latency
• Better support for high-bandwidth applications
• Improved connectivity in busy locations
• Support for connected devices and IoT applications

Actual performance depends on coverage, network congestion, device compatibility, indoor conditions, and the customer’s plan.

Challenges Faced by Telecom Companies

As with all telecom companies, CelcomDigi faces a number of challenges to continuously improve and invest. The cost of building infrastructure is rising, and the telecom market is highly competitive, incentivising companies to provide better services at a competitive price. 

Security is an ever-growing concern as online services grow and users expect faster connections and improved customer service. Additionally, technology is rapidly evolving, and telecom companies need to upgrade their systems to keep up and compete with others for customers’ attention.

How CelcomDigi Differs from Traditional Telecom Providers

Traditional telecom companies mainly focused on voice calls and SMS services, but CelcomDigi has evolved into a much broader digital service provider. The company provides cloud services together with cybersecurity, business solutions, smart connectivity, and digital transformation support. 

The company functions as a mobile operator while also providing technology solutions to both individual customers and business clients. The modern business model of CelcomDigi enables the company to participate more extensively in the digital economy than its traditional telecom service model.

Future Plans of CelcomDigi

Looking ahead, CelcomDigi is planning new investments to continue Malaysia’s growth, including extending 5G networks, bringing connectivity to rural areas, and helping build smart cities. Another priority is supporting businesses to leverage emerging technology like artificial intelligence, automation, cloud, and IoT systems. 

The company is also committed to sustainability by aiming to create eco-friendly digital infrastructure. These initiatives demonstrate that CelcomDigi is not just looking at its existing services, but also at future innovation and national digital development.

CelcomDigi vs Traditional Telecom Providers

Traditional telecommunications services focused heavily on voice calls and SMS. Modern telecom providers operate across a much wider digital ecosystem. CelcomDigi combines mobile connectivity with:

• 4G and 5G
• Fibre broadband
• Cloud services
• Cybersecurity
• IoT
• Business connectivity
• Digital services

This broader model reflects how people and businesses now use telecommunications infrastructure. A mobile network can support smartphones, laptops, connected equipment, cloud applications, digital payments, smart devices, and business systems.

Is CelcomDigi Good for Personal Users?

CelcomDigi can meet the needs of many personal users through its prepaid, postpaid, mobile internet, 5G, roaming, and home fibre services. However, the right plan depends on factors such as location, data consumption, budget, device compatibility, and whether the customer needs mobile or fixed broadband.

Instead of choosing a plan based only on price, compare the included data, network availability, contract terms, speed, roaming requirements, and other benefits.

Is CelcomDigi Good for Businesses?

CelcomDigi offers business services that cover connectivity and digital technology requirements. Its business portfolio includes mobile, fixed, IoT, cloud, and cybersecurity solutions. This range can support organisations that need connectivity alongside digital infrastructure and security services.

Businesses should evaluate their specific requirements, including network capacity, locations, security needs, cloud usage, device management, support, and service-level requirements.

Conclusion

The telecom industry in Malaysia depends on CelcomDigi as a key player, which delivers excellent mobile services, broadband access, and digital solutions. The company provides reliable services to individual customers and corporate clients throughout the country because of its growth through mergers, its extensive network, and its dedication to developing new technologies.
