Why 2G Will Outlast 3G in South Africa

Why It Matters

The unusual shutdown order highlights how affordability and IoT reliance keep 2G viable, reshaping investment cycles and spectrum policy across South Africa’s telecom market.

Key Takeaways

• Vodacom expects 3G sunset before 2G due to higher 2G demand
• Cheapest 4G phone costs ~$42, 16% of South Africa’s basic wage
• Govt cut luxury duty on phones <$132, but VAT still applies
• MTN and Vodacom launched $13 and $5 4G phones to drive migration
• Legacy 2G IoT devices delay full network refarming for 4G/5G

Pulse Analysis

South Africa’s mobile landscape is being reshaped by a paradox: the cheapest tier of connectivity—2G—remains the most resilient. While 3G offered the first mobile internet experiences, its devices now easily revert to 2G, and a sizable segment of consumers still relies on basic voice and SMS services that cost a fraction of modern data plans. Moreover, a long tail of machine‑to‑machine applications—wildlife trackers, vehicle telematics, and remote sensors—continue to run on 2G chipsets because of their low power draw and minimal data needs. This entrenched usage forces operators to keep the legacy network alive longer than typical upgrade cycles would suggest.

Policy interventions have tried to accelerate the shift. In early 2025, South Africa’s treasury eliminated the luxury duty on smartphones priced under R2,500 (about $132), aiming to make 4G devices more accessible. Yet VAT on the same price band remains, preserving a cost hurdle for many low‑income households. Recognizing the gap, Vodacom introduced a $13 (R249) 4G handset in September 2024, and MTN followed with a $5 (R99) subsidised model in May 2025, each targeting over a million users. These ultra‑affordable devices are designed to bridge the affordability chasm, encouraging migration while preserving basic connectivity for those still on 2G.

The eventual phase‑out of legacy networks will unlock valuable spectrum for 4G and emerging 5G services. Refarming 2G bands can boost network efficiency, reduce power consumption, and lower operational expenditures for operators. For enterprises, the transition promises higher‑capacity, lower‑latency connections that can support advanced IoT solutions beyond narrowband applications. However, the timeline hinges on how quickly the ultra‑low‑cost 4G devices achieve market penetration and whether regulators consider further tax reliefs. In the meantime, telecoms must balance legacy support with the economic incentives of a data‑centric future, a dynamic that will shape South Africa’s competitive telecom landscape for the next decade.
