Nigerian mobile subscribers spent N3.67 trillion on internet data in the first half of 2026, underscoring the growing importance of connectivity to consumers and businesses and the enormous sums at stake in the country’s data economy.

The scale of consumption is equally striking. Data released by the Nigerian Communications Commission (NCC) showed that active internet subscribers across licensed service providers reached 157,706,496 as of July 2026, with total internet data usage across networks rising to 1,662,021.45 terabytes in July, from 1,532,172.67TB in June.

For millions of subscribers, few notifications are more frustrating than the one announcing that a data bundle is almost exhausted when they are convinced they have barely used it. A customer buys 10GB, browses the internet, checks social media, watches a few videos and, seemingly within hours, receives the dreaded alert that the data is almost finished. The question that follows is simple: where did the data go?

It is against this backdrop that MTN Nigeria’s newest transparency tools have attracted attention. For millions of Nigerians frustrated by how quickly their data bundles disappear, MTN’s Data Monitor on the myMTN NG app offers a way to track actual consumption. Rather than relying solely on balance alerts, subscribers can use the feature to monitor their usage, identify consumption patterns and better understand the activities responsible for draining their bundles.

The feature is particularly useful at a time when data can disappear through activities users may not immediately notice, video streaming, automatic app updates, cloud synchronisation, WhatsApp backups, auto downloads and hotspot sharing among them. It complements other tracking features on the myMTN NG app, including Device Data Usage, which shows customers how much data their devices have consumed over different periods, giving them a basis for adjusting behaviour rather than just a snapshot of what is left.

Separate from Data Monitor, MTN also runs a Data Calculator covering web browsing, social media, instant messaging, music streaming and video streaming. Where Data Monitor answers “what is consuming my data,” the calculator answers a different question: “how much might this activity consume.” Airtel offers a comparable calculator for subscribers wanting to plan ahead of a purchase, though, as with any estimation tool, MTN notes that actual consumption still varies with video quality, device settings, app behaviour and network conditions.

This kind of usage visibility is not unique to Nigeria. In the UK, networks such as EE, Vodafone and O2 give subscribers an app-by-app breakdown of their data use through their own apps, though a fully itemised session-by-session bill is often only available on request. A closer parallel sits in East Africa, where Safaricom in Kenya markets its data usage feature explicitly as a “statement,” borrowing the language and trust of its widely used M-Pesa statements to show subscribers exactly which apps consumed their bundle and when. It is a useful comparison for where Nigeria’s own transparency drive is headed, showing subscribers a record they can check, not just an estimate they can consult.

Few industry stakeholders are better placed to dissect the issue than the Chairman, Association of Licensed Telecoms Operators of Nigeria (ALTON), Gbenga Adebayo. He said the tools were introduced in response to subscribers’ longstanding demand for greater transparency, particularly amid the persistent perception that unexplained data depletion amounts to data theft by operators.

“The essence of the data calculator is to show you your own consumption and to show you your own behavioural pattern utilisation of data,” Adebayo said, adding that the insight could help subscribers decide how much time to spend on particular apps once they understand the likely data cost. “It puts the control in the hands of the subscribers.”

He noted that consumption varies with the nature of an activity, high-resolution streaming, for instance, consumes far more than text messaging, and argued that making the measurement criteria available answers allegations that operators deliberately deplete customers’ data. “What we have also shown by that tool is that operators have nothing to hide, because if there is something that we are hiding, we will not surrender this measurement criteria or this tool of measurement to the subscribers,” he said.

But individual complaints continue to test that proposition. Nigerian lawyer and MTN customer Zaenab Olawunmi Adams has become one of the more prominent voices in the debate after alleging that about 708.55GB of an 800GB annual bundle was depleted in 104 days, leaving her with only 91.45GB by August after purchasing the plan for N125,000 in May. Her petition, which has drawn more than 27,000 verified signatures, calls for an investigation by MTN and the NCC and a comprehensive audit of consumption records.

MTN’s response has gone beyond the app itself. Its “Data on Trial” initiative, a courtroom-style public forum first held in Lagos and since taken to university campuses, has invited students, journalists, independent auditors and regulators to interrogate the company’s billing system directly. In one such session, audit firm KPMG reviewed MTN’s billing system and found no discrepancy between usage recorded on the network and what customers were charged. MTN Nigeria CEO Karl Toriola told attendees at the flagship event: “We are not asking customers to trust us blindly. We want them to see the evidence and understand exactly how data is consumed.” Airtel has taken a related step with its own Customer Forum in Abuja, themed “Understanding Your Data and Taking Control 2.0,” which featured input from NCC representatives alongside Airtel’s demonstrations on usage and device settings.

Perhaps the clearest sign that the conversation is shifting is what has happened around Adams’s own petition, where fellow subscribers have used the moment to share their own data experiences and tips unprompted, many of them in quote tweets responding to her post, turning one complaint into a broader, largely organic exchange on managing and understanding data use.

Still, in an era where online engagement so easily converts into personal brand and monetisation, it is becoming harder to separate genuine grievance from opportunism. Adams, a lawyer with a public profile, has drawn speculation that the controversy is being used to build visibility for her practice as much as to seek redress. Whatever the truth of that, the responsibility does not shift: it remains on operators and the NCC to close the trust gap quickly enough that no one, genuine complainant or otherwise, has room left to hijack it.

For MTN subscribers, that gap appears to be closing, with Data Monitor now giving them a way to check their consumption rather than simply take it on faith. The same cannot yet be said across the board. With more than 157 million active data subscribers and monthly consumption above 1.6 million terabytes, many Nigerians on other networks are still left asking the same question that opened this conversation: where does the data actually go. Until that answer is available network-wide, the country’s data transparency debate remains only partly settled.
