Cell C CEO Says Cannibalisation Risk Shields Wholesale Market From MTN and Vodacom

Key facts

In an interview published by TechCentral on Aug. 23, 2026, Cell C Chief Executive Officer Jorge Mendes set out the strategic considerations protecting Cell C’s market position as South Africa's premier host for Mobile Virtual Network Operators (MVNOs).

According to reporting by TechCentral, Mendes explained that while the country's two largest telecommunications companies, Vodacom Group Ltd. and MTN Group Ltd., possess substantially larger balance sheets and vast physical network capacity, they face a severe commercial paradox in the wholesale space.

Mendes argued that if MTN or Vodacom were to launch an aggressive price war to take MVNO hosting contracts away from Cell C, they would be forced to offer prospective wholesale partners deeply discounted rates per gigabyte of data and minute of voice traffic. However, because banking institutions, grocery retailers, and digital platforms use MVNO status to bundle low-cost mobile connectivity into their broader customer loyalty and financial services ecosystems, those lower wholesale rates would immediately be passed on to everyday consumers.

The consequence for Vodacom and MTN would be direct self-cannibalisation. Millions of their existing retail mobile subscribers—who currently pay standard consumer tariffs that yield higher average revenue per user (ARPU)—would have a strong incentive to switch to the cheaper, white-labeled MVNO offerings hosted on the same underlying network physical towers.

As a result, any incremental revenue that Vodacom or MTN gained by acquiring a wholesale MVNO contract would be vastly outweighed by the loss of direct, high-margin consumer retail subscription revenue. Mendes characterized this dynamic as a structural trap that prevents the two market leaders from effectively competing for Cell C’s wholesale client base, creating a defensive moat for Cell C’s transformed business model.

Why it matters

The operational dilemma described by Mendes highlights a fundamental structural divide in the South African mobile communications sector, carrying direct implications for corporate strategy, consumer pricing, and institutional investor valuations.

For the primary mobile operators, Vodacom and MTN, defending direct retail average revenue per user (ARPU) is crucial to sustaining their financial model. Both operators invest billions of rands annually into physical infrastructure capital expenditure, including the nationwide deployment of 5G infrastructure, backhaul fiber networks, and backup power equipment—such as commercial diesel generators and industrial lithium-battery banks—required to keep mobile towers operational during widespread electricity load shedding across South Africa. To generate a return on these heavy infrastructure investments, Vodacom and MTN rely heavily on premium direct consumer pricing. Undercutting their own consumer rates to host wholesale partners would erode the financial margins required to fund network upkeep and capital expenditure.

For South African consumers, the growth of the MVNO segment has provided vital relief against historical data costs. Financial institutions such as First National Bank and Capitec Bank, as well as retail chains like Shoprite, leverage MVNO services as customer retention mechanisms rather than standalone profit centers. They frequently subsidize mobile data and airtime for clients who maintain active bank accounts or participate in retail loyalty programs.

Because Cell C operates as an asset-light platform provider, it can offer competitive wholesale rates to these corporate partners without risking the collapse of a massive direct retail ARPU base. This dynamics ensures that the MVNO market remains an active venue for price competition in South Africa, benefiting consumers who seek integrated, low-cost connectivity through non-traditional telecommunication providers.

The dynamics of South Africa’s mobile telecommunications sector have been shaped by decades of market concentration and subsequent regulatory shifts. For much of its history, the sector was dominated by Vodacom—majority-owned by Britain's Vodafone Group Plc—and MTN Group Ltd., which built extensive nationwide coverage footprints following market liberalization in the 1990s.

Cell C entered the market in 2001 as South Africa's third mobile cellular operator, followed later by state-controlled Telkom SA’s mobile division. However, Cell C struggled for nearly two decades under the capital-intensive burden of building, expanding, and upgrading a standalone physical radio access network (RAN) to match the coverage and quality of the two market leaders. The resulting debt accumulation pushed Cell C into severe financial distress, necessitating multiple debt restructuring rounds and recapitalisation efforts, eventually led by Johannesburg Stock Exchange-listed Blue Label Telecoms, which acquired a controlling stake in the company.

To survive, Cell C executed a fundamental pivot between 2020 and 2023, transitioning away from traditional network ownership to an "asset-light" operational framework. Cell C systematically turned off its own physical RAN towers and negotiated comprehensive infrastructure-sharing and national roaming agreements. Under these arrangements, Cell C’s prepaid and hybrid subscribers roam on MTN’s radio network, while its postpaid customers utilize Vodacom’s infrastructure.

By eliminating billions of rands in ongoing tower maintenance, spectrum equipment leasing, and capital expenditures, Cell C rebranded itself as a digital platform and wholesale service provider. This pivot positioned Cell C as the primary back-end network enabler for South Africa’s booming MVNO sector. Jorge Mendes, a veteran executive who previously served as Vodacom South Africa’s Chief Officer of Consumer Business, was appointed Chief Executive Officer of Cell C in June 2023 to steer the company through its operational turnaround and capitalize on its wholesale focus.

Simultaneously, regulatory actions by the Independent Communications Authority of South Africa (ICASA)—including provisions attached to the 2022 high-demand radio frequency spectrum auction—mandated that spectrum recipients provide open wholesale access to MVNOs, further formalizing the legal framework for virtual operators in the country.

Reaction

Following the publication of TechCentral’s report, neither Vodacom Group Ltd. nor MTN Group Ltd. issued public statements directly countering Mendes’s analysis of wholesale market dynamics.

However, corporate strategy teams and equity analysts covering the JSE-listed telecommunications sector have consistently noted the delicate balance market leaders must maintain between wholesale expansion and retail margin preservation. Historically, both Vodacom and MTN have selectively pursued wholesale contracts—such as MTN’s hosting arrangement with Pick n Pay’s PnP Mobile—but both tier-one operators have carefully maintained wholesale pricing thresholds designed to prevent subscriber migration from their high-margin prepaid and postpaid packages.

Market analysts note that institutional investors in Vodacom Group (JSE: VOD) and MTN Group (JSE: MTN) closely monitor direct consumer ARPU as a key indicator of corporate health. Consequently, industry observers regard Mendes's assessment as an accurate reflection of the implicit economic boundaries governing operator behavior in South Africa.
