The Cost of a Bad Call

There is a particular kind of regret that arrives a few seconds too late. You picked up an unknown number, heard a calm voice claiming to be from your bank, and for ninety seconds you believed it. Or the opposite happened: you let an unknown number ring out because, like most Nigerians now, you assume the worst, and it turned out to be the client you had been chasing for three weeks.

Both are bad calls, both carry a cost, and for the average Nigerian professional, that cost is higher, and far more routine, than we like to admit.

We have reached the point where distrust is the rational default. Truecaller’s latest global insight report shows that 51 per cent of all unknown calls to Nigerians are now flagged as spam or fraud, the highest rate in Africa. More than one in every two. When the coin lands on the wrong side that often, people stop trusting the toss altogether, and that single shift in behaviour quietly taxes everyone who works for a living.

Start with the obvious cost: the scam that works. Many begin with nothing more than a phone call, a composed voice posing as a bank officer, an urgent transfer, a one-time code read aloud in a moment of panic. The losses are not abstract. Nigerian banking systems recorded tens of thousands of digital payment fraud incidents annually , with losses running into tens of billions of naira. For a professional, the damage is rarely just the money. It is the afternoon surrendered to the bank’s fraud desk, the police report, the cards reissued, the days of low-grade dread that follow.

Then there is the cascade, the part most people never see coming. One bad call can be the first domino. Surrender the wrong detail and a SIM swap can follow, then the banking app, then accounts that were never mentioned in the original call. The phone number has quietly become the master key to a professional’s financial life. Which means a single compromised call can unlock far more than the caller first asked for.

But the most expensive call of all is often the one that never calls your phone, it calls your mother’s. The scammers know that the people around you, an ageing parent, a younger sibling, a dependent less fluent in their tricks, are the softer way in. A fake emergency, a voice claiming a child has been arrested, a prize that needs a small fee to release. When it works, you carry it twice: once as the money you step in to recover or replace, and again as the guilt of a loss you could not be there to stop. For many Nigerian professionals, that is the real weight of a bad call. It does not land on the most careful person in the family. It lands on the most vulnerable, and then it lands on you.

Then there is the cost no one calculates: the genuine calls that go unanswered. The recruiter, the hospital, the supplier confirming a delivery, or the client calling from a number you do not recognise. When every unknown number is treated as a threat, the real opportunities hidden among them are treated as threats too. This is not only a personal loss, if you run a business, it is the same wound at scale: customers who never pick up, deliveries that fail, and a brand that fraudsters can impersonate freely because no one can tell your genuine call from a fake one. For anyone whose income depends on being reachable, that is not caution. It is lost business, repeated quietly, week after week, with no invoice to mark it.

Put those costs together and a pattern emerges. The cost of a bad call is asymmetric, on a good day it costs you nothing. On a bad one it can cost you an afternoon, a client, a parent’s savings, or an account, and you cannot know in advance which call will be the expensive one. That is precisely the shape of a risk you insure against.

This is where the maths stops being close… Truecaller Premium is N399 a month, less than a bottle of soda in Lagos. For that, it does the things that defuse nearly every scenario above: it automatically blocks known spam and fraud numbers before they ever reach you, it shows you clearly who is calling before you decide whether to trust them, and it extends that protection across the way you communicate every day. It turns an anonymous threat into a known quantity, and an ignored unknown number back into an opportunity you can afford to answer.

Think of it the way you already think about the protections you barely notice. You do not insure your phone because you expect to drop it, you insure it because the one time you do, the cover pays for years of premiums in a single afternoon. Caller protection follows the same logic, applied to the most exposed part of your working life, and your family’s: the number everyone can reach. N399 a month is small, fixed, and predictable. The loss it guards against, a drained account, a scammed parent, a client lost to silence, is large, sudden, and unpredictable. No tool can promise that no fraud will ever reach you. But against a loss that can run into hundreds of thousands of naira, automatic, always-on protection at the price of a soft drink is not a luxury. It is practical.

The bad call will come, to you, or to your business, or to someone you love who answers in good faith. The only real question is whether it finds you protected or exposed. For N399 a month, that is a question you do not have to leave to chance.
