As our lives become increasingly digital, the mobile phone number is no longer just a way to make calls. It has become the key to banking, government services, healthcare, education, commerce and many of the digital services we rely on every day.
That was the focus of my contribution during the WSIS 2026 Leaders' TalkX on building a secure and trusted Digital Public Infrastructure (DPI), where I shared Nigeria's approach to safeguarding one of the foundations of our digital economy: the mobile phone number.
Our approach is centred on one principle: trust.
First, trust in identity. Through our TIRMS platform, authorised institutions can securely verify who is behind every phone number, helping to strengthen accountability and reduce fraud.
Second, trust in networks. Through the Communications Sector Cyber Resilience Framework and the implementation of the Presidential Order on Critical National Information Infrastructure (CNII), government, industry and other stakeholders are working together to strengthen the resilience of our communications infrastructure.
Finally, trust in markets. Consumers need reliable, affordable services and effective redress, while investors need transparent, predictable and consistent regulation that gives them confidence to invest.
Ultimately, resilient Digital Public Infrastructure depends on three things: trusted identities, trusted networks and trusted markets.
