Rising 5G adoption is reshaping Singapore’s mobile revenue mix, offsetting declining voice services and stabilizing market growth through 2030. While legacy voice revenues erode under over-the-top (OTT) pressure, expanding 5G penetration and higher data consumption are driving incremental value. This transition underscores a structural shift toward data-led monetization, compelling operators to accelerate network investments and refine pricing strategies to sustain profitability, says GlobalData, a leading intelligence and productivity platform.
GlobalData’s Singapore Mobile Broadband Forecast (Q4-2025) reveals that the continued growth in 5G service adoption is set to drive the country’s total mobile service revenue at a moderate compound annual growth rate (CAGR) of 0.7% during 2025 to 2030.
Mobile voice service revenue will decline at a 5.8% CAGR over the forecast period due to the widespread consumer shift towards OTT-based communication platforms and the subsequent decline in voice service average revenue per user (ARPU) levels.
Mobile data service revenue, on the other hand, will increase at a relatively healthy CAGR of 4.4% between 2025 and 2030, driven by continued growth in higher-ARPU yielding-5G subscriptions as 5G services become more widely available across the country.
Kantipudi Pradeepthi, Telecom Analyst at GlobalData, says: “5G services accounted for a major share of total mobile subscriptions in 2025 and will go on to represent over 95% of the total mobile subscriptions in 2030.This growth will be primarily driven by continued rise in demand for highspeed data services, ongoing 5G network expansions by MNOs, and a subsequent increase in availability of 5G services across the nation.”
The average monthly mobile data usage is expected to increase from 10.8 GB in 2025 to about 15.1 GB in 2030, driven by the growing consumption of high-bandwidth online entertainment and social media content over mobile networks.
Singtel will continue to dominate the mobile services market in terms of subscriptions through 2030, given its strong position in both the prepaid and postpaid segments and its focus on 5G network developments and expansion across the country. In May 2025 Singtel launched Singtel 5G+, a next-generation evolution of its 5G network. The operator boosted its 5G networks by deploying low-frequency 700 MHz spectrum earlier this year to be able to deliver up to 40% better network coverage in high-rise buildings, underground and indoor spaces, and in remote-areas, and automatically upgraded 1.5 million existing 5G subscribers to 5G+ at no extra cost.
Pradeepthi concludes: “The outlook reflects a decisive inflection point for Singapore’s telecom market, where value creation is increasingly tied to data-centric services rather than traditional voice. Operators that can effectively monetize rising 5G usage, through differentiated offerings, network quality, and enterprise-driven use cases, will be best positioned to capture growth. However, sustaining margins will depend on balancing aggressive infrastructure investments with innovative pricing models in an increasingly saturated market.”
