Singtel’s recent introduction of 5G+ marks a transformative moment in Singapore’s telecommunications landscape, embodying a leap forward in mobile network technology with the commercial deployment of the 700 MHz spectrum. This development is more than just a standard network upgrade; it is a strategic enhancement designed to tackle Singapore’s unique urban challenges while also elevating user experience through advanced features such as network slicing. With roots in earlier 5G rollouts, Singtel’s 5G+ initiative is now setting new industry benchmarks nationally and globally.
The gradual evolution towards 5G+ was seeded several years ago, with initial implementations of 5G starting in 2020. Early coverage targeted high-traffic areas like VivoCity, expanding to near two-thirds nationwide by 2021. However, Singapore’s dense urban environment—with its towering high-rises and underground infrastructures—posed significant obstacles to conventional high-frequency 5G signals. This is where the 700 MHz spectrum comes into play. As a low-frequency band, it offers superior signal penetration and range compared to higher bands traditionally used for 5G, allowing signals to penetrate walls and travel longer distances. The introduction of this spectrum in early 2025 thus addresses critical connectivity gaps, enhancing coverage in challenging locations such as MRT stations, subterranean malls, and industrial areas including Tuas and Jurong Island.
One of the most concrete benefits of deploying the 700 MHz spectrum is the dramatic improvement in signal reliability and reach. Singtel claims a 40% boost in coverage inside high-rise buildings, underground venues, and even remote districts — places where previous 5G iterations struggled. This extended coverage not only improves everyday mobile experiences but also reduces the reliance on dense networks of cell towers. Fewer towers required translates into a more efficient, cost-effective infrastructure that can scale sustainably. Essentially, the lower frequency spectrum operates as a powerful tool to overcome Singapore’s complex urban topology, delivering robust connectivity whether one is inside a bustling mall or in industrial zones where connectivity is often spotty.
Complementing this enhanced physical infrastructure is Singtel’s pioneering use of network slicing technology on a nationwide scale. Network slicing conceptually “carves” the physical 5G network into multiple isolated virtual networks or slices, each optimized for distinct needs. This tailored approach allows users to experience connectivity that aligns specifically with their requirements. For example, bandwidth prioritization for entertainment-heavy activities like HD streaming or ultralow-latency connections essential for online gaming and video conferencing. On the enterprise side, dedicated slices safeguard critical business communications, ensuring security and reliability without interference from consumer traffic. This granular customization of network performance is a defining feature of Singtel’s 5G+ rollout, enabling a dynamic mobile experience that was previously unattainable.
Importantly, Singtel’s commitment to upgrading all existing 5G subscribers to 5G+ using the 700 MHz spectrum at no extra cost signifies an inclusive strategy. It broadens access to faster and more dependable mobile connectivity for all users, rather than reserving advanced capabilities for premium customers or niche sectors. This democratization helps underpin Singapore’s broader digital ambitions—supporting the proliferation of smart city applications, IoT devices, and new-age digital services that rely on seamless, ubiquitous connections. From enabling remote work to enhancing entertainment and empowering innovative business models, the improved network unlocks a host of possibilities that propel both individuals and enterprises forward.
Moreover, Singtel’s efficient use of the 700 MHz band responds to global appeals for more affordable and equitable access to spectrum resources. Organizations like GSMA champion such allocations for their potential to expand network reach while optimizing costs and environmental impact. By making strategic use of this low-frequency spectrum, Singtel not only lifts Singapore’s connectivity standards but also models spectrum management practices that could inspire telecommunications providers worldwide.
Ultimately, Singtel’s introduction of 5G+ represents a watershed for Singapore’s mobile telecommunications. The blend of the pioneering 700 MHz spectrum deployment and comprehensive nationwide network slicing fosters unparalleled coverage, speed, and customization. These advances create a mobile ecosystem where connectivity is both wide-ranging and finely tuned to user needs. Beyond enhancing the consumer experience, they empower businesses and the wider society to exploit the full promise of next-generation wireless technologies. As Singapore sets this new bar, Singtel’s approach signals a future where telecommunications networks become adaptive, resilient, and more democratically accessible, ready to meet the growing demands of a digital-era connected world.
