Luanda –Angola's largest telecommunications operator, Unitel, has been hit by a cyberattack that disrupted voice, mobile data and internet services across the country, just one day before the state-owned company is set to make its debut on the Angolan stock exchange.
According to a company statement released on Tuesday, the cyberattack was detected at 2:20 a.m. local time (0120 GMT) and impacted the company's technology infrastructure, leading to widespread service interruptions nationwide.
Unitel, which serves more than 21 million customers in Angola—home to an estimated 39 million people—said technical teams are working to restore affected services.
"Services remain affected at this time," the company said, adding that restoration efforts are ongoing.
The company did not disclose the nature of the cyberattack or provide a timeline for the full restoration of services.
The incident comes at a critical moment for Unitel, which is scheduled to list its shares on the Angolan stock exchange on Wednesday. The listing forms part of the Angolan government's broader privatization strategy aimed at attracting private investment and reducing state ownership in key sectors of the economy.
The public share offering has already generated strong investor interest, with authorities confirming that the offer was oversubscribed by more than 20%, signaling confidence in one of Angola's largest corporate listings.
While the cyberattack has raised concerns about digital infrastructure resilience, there has been no indication that the planned stock market debut will be delayed.
