Vodacom CEO: Voice Calls Declining Like SMS Did

What happened

Vodacom CEO Shameel Joosub recently highlighted a significant shift in how people communicate, stating that traditional voice calls are rapidly declining much like SMS messages did a few years ago. His observation points to a broader change in consumer behaviour, driven by the rise of Internet-based messaging apps and digital communication platforms.

Why it matters

This development is important because voice communication was once the backbone of mobile service providers' revenues. For decades, people relied heavily on calling and texting as primary ways to stay connected. However, the explosion of data access and smartphone usage in South Africa and globally means many users prefer apps like WhatsApp, Telegram, and Zoom to make calls or send messages.

For mobile network operators such as Vodacom, this trend challenges traditional revenue models that depended on voice minutes and SMS charges. It also signals a transformation in how communications services could be packaged and charged — shifting focus from voice to data plans and digital services.

What this means for South Africans

For everyday South Africans, this shift has a few clear implications:

• More affordable communication: Internet-based calls and messages usually cost much less than traditional voice and SMS, especially when using Wi-Fi or unmetered data bundles.

• Increased connectivity: Messaging apps offer richer communication options, including video calls, group chats, media sharing and end-to-end encryption.

• Need for good data plans: Since voice calls are moving online, dependable and affordable data bundles become essential. This may put pressure on mobile providers to offer competitive data pricing.

However, it’s important to remember that not everyone has seamless internet access yet. In rural areas and for lower-income households, traditional cellular voice and SMS remain vital.

Impact on consumers, jobs and small businesses

Consumers

Consumers stand to benefit from cheaper, more versatile communication methods. However, they need to be able to access reliable data networks and affordable smartphones to fully participate in the digital communication revolution.

Jobs

As the industry shifts away from voice calls, jobs linked to traditional telecommunication services might decline. However, growth in data services, digital content, and app development could create new opportunities. South Africa’s tech sector could benefit if more businesses and consumers adopt internet-based communication.

Small businesses

Small business owners need to adapt quickly to this communication evolution. Using internet-based communication tools can improve how they interact with customers and suppliers, reducing costs and increasing efficiency. For instance, customer support via WhatsApp Business or promotional campaigns over social media can reach more people at lower cost than SMS marketing or traditional phone calls.

On the flip side, small businesses should ensure that their customers also have access to these digital channels. Those targeting lower-income or rural customers might still rely on voice or SMS and should keep these options open.

Risks and limitations

Despite the advantages, there are some risks and limitations South Africans should consider:

• Data costs and access: Not everyone can afford consistent data access. Limited network coverage in some areas means that traditional voice calls are still necessary.

• Digital divide: There's a gap between those who have access to smartphones and data services and those who don't, potentially excluding some people from the benefits of internet-based communication.

• Dependence on technology: Apps and internet-based calls rely on stable network infrastructure and electricity. Interruptions could leave users without reliable communication.

• Security and privacy concerns: While many messaging apps offer encryption, users need to be aware of potential risks around scams, hacking, and misinformation.

Vodacom’s CEO comparison to SMS’s decline serves as a reminder of how fast communication technology evolves and the need for South Africans, businesses, and policymakers to adapt and invest in digital infrastructure.
