I Lost my Mother’s phone number eight years after she died, here’s What Nigeria’s SIM recycling policy taught me. My mother passed away in March 2016. Eight years later, in December 2024, I found out her SIM card had been resold to a complete stranger, recycled sim cards.
I won’t lie, it hit me harder than I expected. It wasn’t just a phone number. It was a small, quiet piece of her that our family still carried around, saved in old contact lists, tied to memories of calls and messages. And just like that, it was handed off to someone else, like it never meant anything at all.
That experience sent me down a rabbit hole, and what I found out changed how I think about the SIM card in my own pocket.
It’s Not a Mistake. It’s the System Working as Designed
Here’s the uncomfortable truth: in Nigeria, you don’t actually own your phone number. The telecom companies do.
Under the Nigerian Communications Commission (NCC) rules, if a SIM line goes quiet for about six months, no calls, no texts, no data, and no recharge the network can deactivate it. Stay dormant a while longer, and the number gets “recycled”: wiped clean and put back up for sale to a new customer.
Why? Money, plainly. Telecom operators pay to maintain every number on their network. An inactive line is a cost with zero return, so from a business standpoint, it makes sense to reclaim it and sell it again.
The Chairman of the Association of Licensed Telecom Operators of Nigeria has said it outright: subscribers don’t hold ownership rights over their SIM numbers, the telecom companies do.
To a telecom company, my mother’s line was just an idle asset sitting unused for eight years. To us, it was hers.
When a “New” SIM Card Isn’t Really New, Recycled Sim Cards
Around the same time I was processing all this, my friend Bekee went through something eerily connected.
Bekee’s Experience
He bought what he believed was a brand new airtel SIM card, only to start receiving aggressive messages from a loan app demanding repayment of a loan he never took. Soon after, strangers began calling and texting, asking for someone else entirely.
Bekee had done nothing wrong. He simply bought a “new” number that wasn’t actually new it had belonged to someone else before him.
The Hidden Risks of Recycled SIM Cards
When a phone number is recycled, the new owner may inherit much more than eleven digits.
Debt Collection Harassment
Loan apps may continue sending repayment reminders because the previous owner registered with that number.
Endless Wrong Calls and Messages
Friends, relatives, businesses, and customers of the former owner may continue calling for months or even years.
Banking and Financial Problems
Banks, fintech apps, delivery services, and digital wallets may still associate the number with its previous owner, leading to verification failures or fraud alerts.
Possible Legal Issues
In extreme situations, the number could previously have been linked to criminal investigations, exposing an innocent new owner to unnecessary scrutiny.
Could You End Up With a Criminal’s Former Phone Number?
This was the question that unsettled me most during my research.
The honest answer is yes.
Once the required dormancy period passes, any eligible number regardless of its history can be reassigned to a completely innocent subscriber. There is currently no public platform where Nigerians can check whether a number has been previously used.
Recognising this growing challenge, the NCC has discussed creating a shared tracking system because phone numbers today are linked to NIN and BVNs, mobile money wallets, banking records, and loan applications. Recycling a number can unintentionally transfer another person’s digital history to someone else.
What Is Changing?
To be fair, the NCC has started introducing reforms.
Line Parking
Subscribers can pay a small fee to reserve an inactive number for up to one year instead of losing it.
Airtime Recovery
There is a proposal to allow former subscribers to reclaim unused airtime within a 12-month grace period after deactivation, subject to proof of ownership.
A Shared Number Tracking System
The proposed Telecom Identity Risk Management System (TIRMS) aims to help banks, telecom operators, and other organisations identify recycled numbers before problems arise.
These initiatives are encouraging, but many are still being implemented.
What You Should Do If You Buy a Recycled SIM Cards
Contact Your Bank Immediately
Inform your bank if you discover that your newly purchased number previously belonged to someone else.
Notify Financial Apps
Reach out to loan apps, fintech platforms, and other services requesting removal of the previous owner’s records.
Keep Evidence
Save screenshots of suspicious messages, wrong-number calls, and loan demands. These records may become useful if disputes arise.
Consider Changing the Number
If the number comes with repeated harassment, criminal references, or persistent debt demands, requesting a fresh number from your network provider may be the safest option.
How Families Can Protect a Loved One’s Phone Number
If you want to preserve the number of a deceased relative, don’t wait until the line becomes inactive.
Ask About Line Parking
Contact the network provider to reserve the number before it qualifies for recycling.
Keep the Line Active
Occasionally making calls, sending texts, buying airtime, or using mobile data may help prevent deactivation, depending on the network’s policy.
My Advice to the Nigerian Communications Commission (NCC)
If regulators are serious about improving SIM recycling, several practical changes could make a significant difference.
Make Line History Searchable
Allow banks, fintech companies, loan apps, and subscribers to verify whether a number is brand new or recycled.
Extend Protection for Deceased Subscribers
Families dealing with the loss of a loved one should have a longer window before numbers become eligible for recycling.
Require Faster Data Removal
Banks, loan apps, and digital platforms should be required to remove old customer records immediately after a number is reassigned.
Improve Public Awareness
The NCC should publish simple, clear information explaining dormancy periods, recycling timelines, and line parking options.
Advice for Anyone Who Receives a Recycled SIM Cards
If your new SIM appears to have belonged to someone else, don’t panic.
Respond to Loan Apps
Explain that the number has been reassigned and request immediate removal from their database.
Inform Your Bank
Let your bank know the number is newly acquired to avoid future verification issues.
Handle Wrong Calls Politely
Inform callers that the previous owner no longer uses the number. Block persistent callers if necessary.
Monitor Your Financial Accounts
Watch for unusual verification requests, fraud alerts, or problems connecting your number to banking services.
Conclusion
Nigeria’s SIM recycling policy exists for understandable business reasons. Telecom companies cannot continue maintaining millions of permanently inactive phone numbers.
But phone numbers have become far more than communication tools. They are connected to our identities, finances, legal records, digital services, and sometimes our most cherished memories.
For my family, my mother’s phone number represented a small connection to someone we loved. Seeing it assigned to a stranger reminded me that, under the current system, memories have no place in telecom databases.
Until stronger safeguards are introduced, every Nigerian should understand how SIM recycling works and what responsibilities come with buying a “new” phone number that may have lived an entire life before reaching your hands.
