The eSIM flaw Nigerian users are being warned about is a serious security risk that could affect millions of devices. On August 23, 2025, the National Information Technology Development Agency (NITDA) released a warning about a critical eSIM vulnerability. This flaw could allow hackers to hijack phone numbers, intercept communications, and even install malicious software on devices.
With MTN, 9mobile, and Airtel now offering eSIM services in Nigeria, the flaw is a major concern for mobile users and businesses alike.
What Is the eSIM Flaw Nigeria Users Should Know About?
The flaw comes from a software vulnerability in Kigen’s eSIM operating system, linked to the GSMA TS.48 Generic Test Profile (version 6.0 and earlier).
In simple terms, this “test setup” used during device manufacturing wasn’t fully removed in some eSIMs. Hackers can exploit it to gain access.
Possible Risks of the eSIM Flaw Nigeria Faces
-
Hijacking mobile numbers.
-
Intercepting calls and SMS messages.
-
Installing hidden backdoors on devices.
-
Cloning eSIM profiles.
-
Stealing sensitive cryptographic keys.
This makes the flaw a serious cybersecurity issue for Nigerians using eSIM-enabled devices.
How Big Is the eSIM Flaw Problem?
Globally, the eSIM flaw affects over 2 billion devices — from smartphones and tablets to smartwatches and IoT devices.
In Nigeria:
-
MTN and 9mobile started eSIM trials in 2020.
-
Airtel joined with its eSIM rollout in 2023.
-
Usage is growing, though official user numbers are not published.
This means the eSIM flaw Nigeria users face is not a small issue—it could impact a wide range of people and businesses.
NITDA’s Warning on the eSIM Flaw Nigeria Is Facing
NITDA has issued a strong warning about the eSIM flaw Nigeria is currently facing, urging device makers, mobile network providers, and users to take action quickly. To fix the problem, the agency explained that phones and other devices need to receive updates, known as Kigen OS patches, which are sent automatically over the air. They also advised upgrading systems to the latest GSMA TS.48 version 7.0 and removing any old test settings that could leave devices exposed. NITDA stressed that acting fast is the best way to stop hackers from taking advantage of the flaw and to keep Nigerians safe from mobile security risks.
How Nigerians Can Protect Themselves
If you’re using an eSIM in Nigeria, here’s what you should do:
-
Update your phone: Always install the latest software updates.
-
Contact your provider: MTN, 9mobile, or Airtel can confirm if patches are applied.
-
Avoid unofficial profiles: Don’t use unverified eSIM QR codes or test versions.
-
Stay informed: Follow updates from NITDA and your mobile operator.
Why the eSIM Flaw Nigeria Users Face Is a National Issue
Beyond personal data risks, the flaw has wider implications:
-
Cybercrime threats: Stolen numbers can be used for fraud.
-
Financial risks: Mobile banking apps and USSD services could be compromised.
-
National security: Sensitive communications on eSIM devices may be intercepted.
This is why the eSIM flaw Nigeria faces is not just a personal problem—it’s a national cybersecurity challenge.
Conclusion: Staying Ahead of the eSIM Flaw in Nigeria
The eSIM flaw Nigeria is dealing with shows how fast technology can create both opportunities and risks. While eSIM makes life easier, it also introduces new security challenges.
By updating your device, checking with your provider, and staying alert, you can protect yourself from potential threats.
