South Africa’s digital future hinges on how effectively its industries embrace the Internet of Things (IoT). From agriculture and mining to healthcare and logistics, connected devices are driving smarter decisions, greater efficiency, and sustainable growth. Yet many sectors still rely on GSM-based connectivity (2G/3G/4G) to power their IoT deployments—a choice that increasingly exposes them to operational, financial, and strategic risks.
With the planned sunset of legacy GSM networks by 2027 and the rise of low-power, scalable alternatives like Sigfox, the time to pivot is now.

Final Takeaway
GSM-based IoT connectivity is increasingly risky in South Africa’s evolving infrastructure landscape. From coverage and cost to scalability and security, GSM falls short of the demands of modern, data-driven industries. Purpose-built IoT networks offer a resilient, future-proof alternative – designed to thrive in South Africa’s rural, industrial, and urban environments.
