Businesses deploying connected devices in Singapore require highly reliable mobile connectivity. Coverage gaps, network congestion or outages can directly affect operations, revenue and service quality.
Smart Walkie provides M2M and IoT SIM cards for Singapore with multi-network connectivity across Singtel and StarHub, designed to deliver the best possible coverage and business continuity for long-term and mission-critical deployments.
Designed for Business-Critical IoT Deployments
Unlike consumer SIM cards, M2M and IoT SIM cards are built for devices that operate continuously and unattended over many years.
Smart Walkie IoT SIM cards are commonly used in a wide range of deployments, including GPS trackers, fleet management systems, asset tracking, solar monitoring systems, vending machines, point-of-sale terminals, connected cameras, smart watches, tablets, and connected vehicles.
They are also suitable for NB-IoT and LTE-M devices, such as smart meters, environmental sensors, building automation systems and other low-power, long-lifecycle applications.
These use cases require stable connectivity and consistent coverage rather than consumer-style data speeds.
Multi-Network IoT SIM for Best Coverage in Singapore
Smart Walkie’s Singapore IoT SIM automatically connects to Singtel and StarHub, selecting the strongest available network at any location.
This multi-network capability improves coverage in environments such as underground car parks, industrial estates, ports, warehouses, construction sites and dense urban areas. If one network experiences congestion or coverage issues, devices can continue operating on the alternate network, helping to reduce downtime.
This approach is especially valuable for distributed deployments such as fleets, vending machines, solar installations and nationwide retail systems.
5G and 4G Data Connectivity
Smart Walkie IoT SIM cards support 5G and 4G LTE networks in Singapore, ensuring compatibility with modern IoT hardware and long-term network evolution.
The SIMs are data-only by default, optimized for machine-to-machine communication. SMS support is available as an option for use cases such as alerts, device provisioning or backup signaling.
Built for Business Continuity
For business deployments, connectivity reliability is critical. Smart Walkie IoT SIM cards are designed to support business continuity through:
- Multi-network redundancy via Singtel and StarHub
- Nationwide coverage across Singapore
- Support for NB-IoT, LTE-M, 4G and 5G devices
- Long-term SIM stability for deployed equipment
This makes Smart Walkie a strong alternative to single-network or consumer SIM solutions.
Centralized SIM Management
All Smart Walkie IoT SIM cards include access to a centralized management portal, enabling customers to manage and monitor large numbers of SIMs efficiently. This is well suited for system integrators, fleet operators, retailers and enterprises managing diverse device types.
