Cheaper data is coming…These SA Telecoms stocks stand to benefit!

For years, South Africa’s mobile operators have competed by building bigger networks, rolling out faster 5G and convincing us to buy ever-larger data bundles.

That era may be coming to an end.

The next battle will be fought over something far simpler and far more consequential for investors: who can survive a world where mobile data steadily becomes cheaper.

Recently, three seemingly unrelated developments have quietly set the stage for what could become the biggest structural shift in South Africa’s telecoms industry since the arrival of 4G

Three changes to data… One big consequence!

The first development came in January.

ICASA gazetted new regulations requiring operators to automatically roll over unused data, voice and SMS bundles at the end of their validity period. If upheld, consumers would no longer lose unused data.
Consumers must opt in before being migrated onto out-of-bundle tariffs – eliminating one of the industry’s most profitable pricing practices: selling data that customers never actually consume.

Unsurprisingly, both MTN and Vodacom have taken ICASA to court, arguing the regulator exceeded its legal powers and that the rules could reduce competition rather than increase it. Whether the court agrees is almost beside the point. The message from regulators is unmistakable: they want South Africans paying less for mobile data. And they’re not asking nicely anymore.

The second development arrived almost unnoticed this week.

ICASA gazetted South Africa’s new National Radio Frequency Plan on 24 July and buried within hundreds of pages was an announcement with enormous long-term implications. The upper 6GHz spectrum band has been officially designated for future mobile broadband, including 5G and eventually 6G.

Think of spectrum as the highway that mobile operators use to deliver data. The more lanes they have, the more traffic they can carry. More capacity lowers congestion. Lower congestion reduces operating costs. Lower costs, over time, translate into cheaper data. This lays the groundwork for one of the biggest future spectrum additions in years.

The third piece of the puzzle is the baseline South Africans are starting from.

Despite years of competition and repeated regulatory pressure, the average South African still pays roughly R20 per gigabyte of mobile data.

South Africa ranks 67th out of 100 countries on data affordability – meaning only 33 countries in the world have more expensive mobile data than we do, while 27 African nations alone already offer cheaper data than South Africa.

Prices have been falling. A prepaid gigabyte dropped from R100 in 2020 to R79 in 2025. Postpaid 5GB packages came down from R199 to R99 in the same period. Progress, but not nearly enough, and not nearly fast enough.

Put those three developments together and one conclusion becomes difficult to ignore…

The long-term direction is clear – mobile data is becoming cheaper, more abundant and far more consumer-friendly. For consumers, that’s overdue and welcome. For investors, it creates clear winners and losers.

The data companies under pressure

Vodacom (JSE: VOD) has the rawest exposure. South Africa’s largest mobile operator by subscriber count has significant exposure to consumer mobile revenue. The rollover regulations hit it directly. MVNO competition from resellers already offering cheaper data than the major operators also impact it. The 6GHz spectrum helps long-term, but only after billions in capital expenditure to deploy it.

Vodacom’s saving grace is diversification. VodaPay, enterprise connectivity and cloud services are growing contributors, but its largest business unit, consumer mobile, is squarely in the crosshairs.

Telkom (JSE: TKG) faces the sharpest structural squeeze. It has historically competed far more aggressively on mobile data pricing than MTN or Vodacom. And there’s less of a financial services or enterprise cushion to absorb margin pressure.

Telkom Mobile already prices more aggressively than its competitors, with some of its best large bundle offers reaching as low as R4.73 per gigabyte. Regulatory-driven price compression therefore hits margins that are already thin. When you’re already selling cheaply, selling even cheaper is genuinely painful.

The twist is that Telkom could simultaneously be one of the biggest long-term beneficiaries of the new spectrum. Historically disadvantaged on spectrum relative to MTN and Vodacom, better capacity could finally allow Telkom to compete on network quality.

Instead of competing almost exclusively on price, it may eventually be able to compete on customer experience too. Telkom is both the most exposed company in the short term and potentially one of the biggest beneficiaries over the long term.

The data companies best placed to survive

MTN (JSE: MTN) isn’t simply a mobile operator. It owns one of Africa’s fastest-growing fintech businesses, has significant enterprise operations and generates earnings across multiple African markets.

That diversification matters enormously when pricing comes under pressure in a single market. If South African data margins compress, MTN has other earnings engines running simultaneously. It probably loses some pricing power. It almost certainly doesn’t lose the war.

The wild card and quiet winner…

The most fascinating company in this entire story is also the newest listed one.

Cell C’s (JSE: CCD) capex-light model (roaming on MTN and Vodacom’s infrastructure rather than building its own nationwide network) means it sits outside the brutal capital expenditure cycle that the 6GHz spectrum deployment will require.

While MTN and Vodacom spend billions deploying new spectrum, Cell C avoids the enormous network capex burden carried by traditional operators. In a margin-compression environment, a lighter capital structure gives Cell C more flexibility if industry pricing becomes more competitive.

The regulatory environment also plays to Cell C’s strengths. Brands like Capitec Connect and FNB Connect have built loyal customer bases by reselling Cell C’s wholesale data at prices that undercut the major operators. If ICASA’s regulations force greater pricing transparency and eliminate punitive bundle expiry rules across the industry, consumers become more willing to shop around, and a newly competitive pricing environment is exactly the conditions in which Cell C’s value positioning gains traction.

Ironically, one of the biggest beneficiaries of cheaper mobile data may not be a network operator at all.
Blu Label Unlimited (JSE: BLU) is still viewed by most investors through the lens of Cell C. That’s yesterday’s story.

With Cell C now separately listed, Blu Label’s investment case is increasingly returning to its core distribution business – processing millions of prepaid airtime and data transactions through hundreds of thousands of informal retail points across South Africa. Spaza shops. Garage forecourts. Corner stores. Every transaction flowing through its retail network generates revenue for Blu Label.

Its economics are fundamentally different from every other company in this story. Blu Label doesn’t need expensive data. It needs consumers buying data. Those aren’t the same thing.

Imagine data prices fall 30% but consumers buy twice as much because it’s suddenly affordable, which is exactly what happened with broadband, cloud computing and AI infrastructure as each became cheaper. The operators experience margin pressure. Blu Label processes significantly more transactions. Its earnings are driven by activity, not by the price per gigabyte.
