Capitec’s bombshell announcement that free calls between Capitec Connect users are now available marks a watershed moment for South Africa’s telecoms landscape – though perhaps not in the way most people think. When Capitec CEO Graham Lee unveiled this development on Wednesday, he wasn’t unveiling a revolutionary subsidy of a high-value product. Rather, he was giving away something the market has already decided is worth remarkably little.
To understand what’s really happening here, you need to step back and look at the brutal economics reshaping mobile telecommunications. The South African mobile industry spent its first two decades printing money from voice calls. For roughly 20 years, voice revenue carried the networks, powered the balance sheets, and drove share prices higher. Data? It barely registered as significant. That world has been turned upside down. Today, voice has been comprehensively devoured by data, messaging apps, and regulatory pressure, and the economics have flipped entirely on their head.
The real commercial logic behind Capitec’s move reveals something far more nuanced than a generous gift to consumers. Capitec isn’t a mobile operator trying to build a mobile business from scratch – it’s a bank using Capitec Connect as one of several strategic hooks to deepen primary banking relationships. Free calls within families using Capitec Sims creates what industry insiders call a network effects play. The more household members locked into the Capitec ecosystem, the stickier the entire banking relationship becomes. It’s clever positioning, but it’s not charity.
Cell C, which operates the underlying network infrastructure for Capitec Connect, declined to discuss the specifics of its wholesale arrangements with its largest MVNO customer. However, the company’s carefully worded response to our enquiries tells you everything you need to know. Cell C noted that termination rates represent just one component of voice economics, alongside traffic profiles, technology choices, and proposition design. Translation: there’s plenty of room to make free on-net calls work when the product being given away costs almost nothing to deliver.
Understanding why free calls between Capitec Connect users barely move the needle
Here’s the technical reality that makes this whole deal possible: when two Capitec Connect Sims call each other, they’re communicating across the same underlying infrastructure – Cell C’s network. There’s no inter-operator termination charge to calculate because the call never leaves Cell C’s network. On modern 4G or 5G infrastructure carrying voice through VoLTE technology, the marginal cost of a minute of call time is trivial. The expensive bits – spectrum licences, tower infrastructure, and backhaul capacity – are already paid for regardless of whether calls are made or not.
This is precisely the kind of deal that becomes remarkably easy to strike with a network operator like Cell C when you’re essentially giving away something with minimal variable cost. It’s not heroic generosity; it’s straightforward business pragmatism dressed up as consumer benefit.
The broader trend in voice pricing tells the real story. Look at MTN’s newly launched Pi brand, a digital network operator running directly on MTN’s infrastructure. Pi offers 500 minutes of voice calls and SMS messages for just R79 per month – that works out to under 16 cents per minute. Meanwhile, data plans start at R99 monthly for 5GB of usage. Melon Mobile, another MVNO operating on MTN’s network, bundles “unlimited” voice and unlimited SMS into its mobile plans, with the 5GB package priced at R199 monthly and the top-tier 50GB plan at R599.
Vodacom’s PowerFlex and MTN’s SuperFlex Sim-only tariffs have bundled unlimited calls at mid-tier price points for considerable time already. In this competitive landscape, Capitec’s announcement reads less like a thunderbolt and more like a necessary catch-up move – though it does push the pricing bar down further at the prepaid end of the market, where most South Africans actually live and where competitive intensity burns fiercest.
What fundamentally matters less about Capitec’s move now compared to even five years ago is that it involves something the market has already been abandoning wholesale. South Africans migrated to WhatsApp and other messaging platforms not primarily because voice calls were expensive, but because data-based communication proved genuinely superior. People prefer voice notes over real-time calls. They like the asynchronous nature of text. A generation of consumers has simply stopped thinking about “making a call” as dialling a number – they think about sending a WhatsApp message or voice note instead.
The shift is stark when you look at where operator revenue actually comes from these days. Voice once accounted for the bulk of mobile service revenue in this country. Today, service revenue growth is almost entirely a data story, with voice in perpetual structural decline. The major operators are responding rationally by extracting what they can from customers with sticky contracts while pouring capital into data and fixed-wireless products that will actually carry the next decade.
This context explains why Capitec’s announcement, whilst undoubtedly smart strategy for a fintech company, doesn’t pose the existential threat to operators that similar moves might have posed a decade ago. The operators have already lost most of the voice revenue they were ever going to lose. What’s left is a long tail – business customers with inflexible needs, older subscribers comfortable with traditional calling, and off-net calls to people on competing networks – that proves less price-sensitive and more captive. Capitec’s free on-net calling offer represents, in many ways, the final rites for a market segment that was already moribund.
The ghost of Shameel Joosub’s Spanish experience haunts current market debates
Shameel Joosub, Vodacom Group’s long-serving CEO, has been sounding alarm bells for years about fragmentation risk in South Africa’s mobile market. Last November, he publicly warned that “lots of players and lots of regulation” had damaged European markets, contrasting that with better outcomes in more consolidated markets. He’s earned the right to hold that view – he personally ran Vodafone Spain from early 2011 through August 2012, precisely the period when that market transitioned from a stable three-operator oligopoly to the hypercompetitive, razor-margin sector it remains today.
Joosub’s concerns carry genuine substance. There is a real and legitimate risk that aggressive MVNO pricing, declining termination rates, commoditised data, and a sluggish economy combine to erode operator margins so severely that capital expenditure on rural 5G expansion and fibre deployment inevitably slows. The investment numbers are substantial – Vodacom spent R11.5-billion on its South African network in financial year 2025, MTN deployed R9.8-billion, and Telkom invested R5.8-billion. That’s discretionary spending. If returns compress, these numbers will compress too.
However, any argument that regulators should ease pressure on operators to protect margins requires serious scrutiny. The mobile termination rate presents the clearest test case. Under communications regulator Icasa’s current glide path, the mobile termination rate for large operators drops from the current 7 cents per minute to 5 cents on 1 July 2026 and to 4 cents on 1 July 2027. Operators will inevitably lobby to slow or reverse that trajectory, arguing that free calling is eroding network economics.
But this argument conflates two fundamentally different phenomena. Lower termination rates didn’t kill voice as a revenue line – WhatsApp and the smartphone did that. Termination rates historically kept retail call prices artificially elevated beyond what they should have been, and Icasa’s long glide path, descending from a termination rate peak of R1.25 per minute 16 years ago, represents a rational market correction. Reversing course would amount to asking consumers to subsidise a business model whose decline is structural rather than regulatory in origin.
Better policy tools exist for supporting network investment – spectrum policy, rapid deployment frameworks, and targeted rural coverage obligations all serve network development more effectively than propping up the price of a product consumers have already abandoned. The question isn’t whether Capitec’s announcement damages the market economically. The answer is probably that it doesn’t do much damage at all, because the market repriced voice around zero years ago.
The genuinely interesting question is what operators build next. Voice was a 30-year wealth-generating product. Data is already commoditising rapidly. Bandwidth-intensive services on top – streaming, gaming, cloud services – are following closely behind. Ralph Mupita, MTN’s group CEO, has already recognised this reality, turning aggressively toward data centres and artificial intelligence. He knows data will become a commodity (it’s already well on its way), and MTN along with the rest of the industry must figure out where genuine profit pools will exist.
The operators destined to thrive through the next decade will be the ones that successfully monetise what sits above basic connectivity. Financial services represents one increasingly important opportunity – which is precisely why operators now compete directly against companies like Capitec. The banking and fintech spaces have become territories where traditional mobile operators must compete to survive.
