South Africa’s next broadband war may be won by a bank

South Africa’s next broadband war may be won by a bank


I have spent 28 years in African telecommunications watching operators compete for customers. The playbook has been consistent: build the network, own the spectrum and control the customer. The assumption underneath all of it is that the company with the infrastructure wins.

Capitec is about to test that assumption in the fixed broadband market, and the outcome matters more than most people realise.

In April, at its full-year results presentation in Stellenbosch, Capitec said it intended to launch home broadband services, without elaborating on how. Group CEO Graham Lee used the same platform to scrap call charges between Capitec Connect Sim cards altogether, and to extend the bank’s device financing to premium smartphones. Connectivity, on that evidence, is not being treated as a side business. It is being treated as a utility that belongs inside a banking relationship.

That is not how a telecoms company thinks; it’s how a platform company thinks.

Capitec has 25 million banking clients. It is South Africa’s largest bank not by assets but by customer numbers – the thing that matters most in a broadband land grab. Its brand is trusted in precisely the segment fixed broadband has historically failed to serve: the lower-to-middle income mass market.

The mechanics already exist for it to be successful in home broadband. Capitec Connect is a mobile virtual network operator (MVNO) hosted on Cell C, with more than 1.5 million active clients and a net income contribution of R442-million for the year to February 2026. Cell C is itself a fibre ISP reseller. The plumbing is there. Capitec does not need to build anything to start selling home broadband. It needs fibre network operator (FNO) partnerships, a product in the banking app and the distribution advantage it already has.

Fixed-mobile convergence

The financial logic sharpens the picture further. Capitec Connect’s data traffic effectively tripled last year, to 40.5 petabytes. Mobile data is expensive to deliver; it carries spectrum costs that fibre does not. Every megabyte shifted from Cell C’s mobile network onto a fixed connection at home is a cheaper megabyte for Capitec. It can either protect margin or, consistent with its history, cut prices and drive volume. Either outcome reinforces the competitive position.

Add the fixed-mobile convergence dimension. European operators have spent the past decade demonstrating that customers who take both fixed and mobile from the same provider churn at significantly lower rates. The household that buys banking, mobile data and home broadband from Capitec is the most valuable and most sticky customer they can have. This is not because of the connectivity revenue alone, but because of the daily engagement it enables across all the bank’s services.

DataEQ’s SA Telecoms Customer Experience Index: Mobile Virtual Network Operators 2026, which analysed more than 42 000 social media mentions across X, Facebook and Hellopeter between October 2025 and March 2026, found that Capitec Connect’s operational net sentiment was 4%.

That 4% is not an industry-wide malaise. Across the five MVNOs DataEQ tracked, operational net sentiment averaged 56% — and FNB Connect, a direct banking rival running the same branch distribution play, scored 80%. Capitec sat second from bottom, ahead only of Standard Bank Connect.

Customer service sat at -73%, turnaround time at -82% and staff competency at -71%. Billing errors were raised repeatedly with no resolution. Branch staff were unable to assist with Connect-specific queries. Self-service channels returned errors on basic transactions.

Those numbers don’t compare well against the picture from a year earlier, when the PwC South African Telecommunications Sentiment Index, also produced with DataEQ, put Capitec Connect at +88% – among the highest scores anywhere in the sector.

To be sure, the two measure different things. The earlier figure was public net sentiment, essentially the tone of the conversation about the brand. The 4% is operational net sentiment, aggregating customer service, account administration, network quality and responsiveness. A brand customers speak warmly about but that struggles to serve them once they have bought is not a contradiction. It is the argument of this piece.

The brand equity is real. Customers cite years of loyalty to Capitec as a reason for taking the Connect product, and purchase intent is strong. What follows the sale is not yet matching the promise.

Some of this is structural. MVNOs are accountable for network failures they did not cause and cannot fix. When Cell C has an outage, Capitec Connect absorbs the reputational consequence. That vulnerability does not disappear in home broadband. If an FNO partner has an installation backlog or a network fault, Capitec’s brand carries the damage.

Telkom is the obvious parallel. Telkom has owned the pieces to win the mass market fixed broadband customer for years: Openserve is a decent FNO, and there is a mobile network on the other side. They have never executed it effectively. The infrastructure is there; the service experience drove customers away. The Telkom retail brand became a liability sitting on top of genuinely useful infrastructure.

What happens next

Capitec’s entire competitive identity is the opposite of that. Its promise is one of simplicity, low price and smooth functionality. That is what beat the big four banks from a standing start. The question is whether it can bring the same discipline to a market where it depends on partners for infrastructure quality and where the failure modes are nothing like banking’s.

I bank with FNB. I have been a Vodacom mobile customer since 1998. My home fibre runs through Cell C. Three separate providers, no convergence, and I am not switching any of them. That is not a confession of irrationality but rather an honest description of how sticky customers are, even when a better bundled offer might exist on paper.

Which is precisely why the Capitec argument is not about winning customers like me. It is about who is best positioned to onboard the next five million fixed broadband customers in South Africa: people who do not yet have home connectivity, or who are on expensive mobile data because the barriers to fixed broadband have been too high.

Alan Knott-Craig’s Fibertime is already showing what happens when you remove those barriers. R5/day, no contract and vouchers sold at spaza shops. For the first time in South Africa, fibre is cheaper than mobile data for low-income households in areas where it is available.

broadband

Capitec’s version of that story is a banking app with 20 million users, trusted billing relationships and device financing already in place. If it partners with the right FNOs and brings the same pricing aggression it applied to mobile data, it is not competing with Vodacom or MTN for existing broadband customers. It is unlocking a market the operators have largely left on the table.

The opportunity is real and so is the execution risk. The customer experience data says the MVNO service layer cannot yet carry the weight of the brand promise. Fix that before scaling home broadband and the thesis holds. Fail to, and Capitec risks doing to its banking brand what poor service has done to every incumbent operator in this market.

Nothing about that is predetermined. But it is the variable that decides whether this becomes a transformation story or a cautionary tale.
