Disadvantages

• Own 5G Network Still Under Deployment: CelcomDigi's independent second 5G network was under active construction as of 2025, meaning 5G availability currently depends on the shared DNB wholesale infrastructure rather than the carrier's own standalone 5G architecture, according to RCR Wireless CelcomDigi 5G Deployment Report published July 2024.

• Mixed App User Experience At Launch: The unified CelcomDigi App received criticism for slow loading times and login errors after its October 2025 launch, with Reddit user reports and app store feedback flagging performance issues on both iOS and Android in the first two months of availability, according to Reddit Malaysia Community Post published November 2025.

• Declining Prepaid Segment Revenue: CelcomDigi strategically shifted away from one-time prepaid SIM acquisitions in 2025, resulting in a 1.2% year-on-year decline in service revenue for Q1 2025, which may signal reduced value options for budget-focused prepaid customers, according to The Edge Malaysia Q1 2025 Earnings Report published May 2025.

CelcomDigi Vs Competitors

Malaysia's mobile market is dominated by three operators — CelcomDigi, Maxis, and U Mobile — with CelcomDigi holding approximately 50% mobile revenue share, Maxis approximately 37%, and U Mobile approximately 13%, according to Macquarie Research via Soyacincau published November 2024.

CelcomDigi leads on coverage breadth and subscriber volume, while U Mobile secured Malaysia's second 5G network license over CelcomDigi and Maxis in late 2024, positioning it as the emerging 5G challenger. Maxis holds competitive speed metrics in dense urban areas and a strong postpaid premium positioning.

CelcomDigi suits subscribers who prioritize nationwide coverage reliability and the widest rural signal reach. Maxis is the stronger option for premium urban postpaid users seeking competitive download speeds in Kuala Lumpur. U Mobile is the most relevant choice for subscribers focused on early access to Malaysia's independent second-generation 5G network.
