MTN's record profit runs on data its own customers say is disappearing

MTN Nigeria just reported the best half-year in its history — ₦1.09 trillion in pre-tax profit, up 75% from a year earlier. Its roughly 92 million Nigerian subscribers spent ₦1.7 trillion on data in those six months, more than on any other product the company sells. And yet the same company spent its spring and early summer publicly putting its billing "on trial" in a Lagos hotel, because those very customers keep insisting their data vanishes too fast — and MTN keeps giving them the same answer.

That contradiction is the whole story, and it is an investor's story, not just a consumer gripe. The profit recovery the market is rewarding runs on data. So does the complaint that could throttle it.

What the customers say, and what MTN keeps telling them

The grievance is easy to state: bundles that used to last are gone in days. Subscribers cite a 5GB plan exhausted in three days, and phone data meters that disagree with what the operator's system reports charging. The complaints are loud enough that they have spilled onto social media, drawn a threat of an "OccupyMTN" protest, and pushed the regulator into the picture.

MTN's defense has been consistent — literally the same thing every time. It bills only for data actually consumed. The real culprits are background apps, automatic updates, and cloud backups chewing through megabytes while you sleep. Mobile data in Nigeria is among the cheapest anywhere. And its billing is independently audited by KPMG and monitored by the regulator. In June it went further, hosting a "Data on Trial" session in Lagos where KPMG reported "perfect alignment" between the usage its portal showed and the data it charged.

None of that has satisfied the people paying. The pushback isn't really about whether the meters match — it's that the explanation collides with lived experience. In January 2025 regulators approved a 50% tariff increase, so the prices on those bundles rose even as the experience of "data draining" got worse. The company can cite audits all day; the customer just knows they paid the same-ish money and got less.

Why the investor should care: this is the engine

Strip away the consumer noise and the financial logic is stark. MTN Group's service revenue rose 17.5% in constant currency in the first half of 2026, and data — not voice — is now roughly half of it, with data revenue up 29% to R57.6 billion. Nigeria is the single largest contributor, about 31% of group revenue and the biggest source of profit. This is not a company that can shrug off anger in its largest market.

The detail that matters most, though, is lurking in the second quarter: ARPU is falling.Dollar ARPU dropped 8.8% year over year to $3.41, and even naira ARPU inched down. That is the first decline since mid-2025, and it matters because it pins down exactly where MTN's growth is coming from now. The 50% tariff hike that powered 2025 is fully annualized — there is no bigger bill to pass through this year. Subscriber growth is being driven by adding 7.5 million new, price-sensitive customers. So the growth engine has shifted from "charge the same people more" to "get more out of a big, low-value base that is already unhappy about how fast its data runs out."

In other words, the very monetization the market is betting on — extracting higher spend per subscriber — is the exact friction point the data backlash is aimed at.

The regulator is the swing variable

This is where the macro lens has to yield. The story here is not one global cycle; it is a market-specific failure that can overpower the liquidity read, and it is worth naming it as such.

The driver of MTN's turnaround is real and cyclical. A stabilised naira — N1,380 to the dollar at the end of June versus N1,530 a year earlier — flipped a Nigerian operation that had been racking up currency losses into a profit machine. Data adoption is on an exponential path: national data consumption grew nearly 47% year over year in June, smartphone penetration is at 66% and climbing, and MTN controls roughly half the mobile market with over 90 million subscribers. That is the technology-adoption clock doing its compounding thing.

But the second clock is the one the data-depletion fight is moving. The Nigerian Communications Commission granted the 50% tariff hike in January 2025 on the explicit condition that operators improve the network. Instead, it has moved from warnings to fines — about ₦12.4 billion ($8.85 million) levied for chronic quality-of-service failures, with MTN, as the biggest operator, expected to carry the largest share. And the regulator is now writing the exact rules the depletion complaints are about: a framework that auto-refunds failed transactions, and new regulations on transparent data-usage tracking. The tariff increase was effectively a pact — money in, quality up — and the regulator is signalling the operators broke their side. If consumer anger translates into pricing action, the data engine loses another cylinder just as the tariff tailwind fades.

What this adds up to

The honest reading has two layers, and neither is a denial of the other. The recovery is genuine and macro-supported: a stabilising currency and an exponential data curve turned MTN from loss-maker to dividend-payer with record Nigerian profits. That part is not in dispute.

The risk is narrower and more specific, and it is the part a subscriber-based investor should hold onto. MTN's next leg of profit has to come from wringing more revenue out of a subscriber base that believes it is being short-changed, at a moment when the regulator holds real leverage. The company answered the "data depletion" question with transparency roundtables and an audited portal — the same explanation, better dressed. What the 100 million want is not a clearer meter; it is an explanation that accounts for a year in which prices jumped and the bundles still seemed to shrink.

Watch the ARPU line and watch what the NCC does next. Both are leading indicators for the same thing: whether the market rewards MTN for the recovery it already had, or starts pricing the risk that the people funding that recovery decide they have had enough.
