An Angolan startup has launched a homegrown instant-messaging application that allows users to send messages without consuming mobile data, targeting the millions of Angolans who remain priced out of conventional data packages.
Ping Chat — the name evoking the sound of an incoming message notification — is the flagship product of WiConnect, an Angolan technology startup. The app resembles WhatsApp in its core functionality but operates on a zero-rating model: data traffic generated by the platform is not deducted from the user's mobile balance, thanks to commercial agreements with Angola's main mobile operators. The application has been available since last month on leading app stores and in a web version, with an official launch planned for October following three years of development and more than $400,000 in investment.
In its first four weeks of operation, Ping Chat has attracted 800 users. The app was designed specifically to address structural barriers in Angola's telecommunications market, where mobile data packages remain expensive relative to household incomes. Those conditions help explain the country's relatively low mobile broadband penetration: according to the National Communications Institute (INACOM)'s 2025 statistical report, only 48 out of every 100 inhabitants are connected to the internet, even as the total number of mobile telephony subscribers exceeds 28.4 million.
WiConnect engineered the application so that its messaging traffic is zero-rated — meaning internet data consumed within the app is not charged to the customer. 'It does not consume data credit, under agreements with national operators, and users accumulate points by watching advertisements, which they then use to send messages,' Paulo Araújo, the startup's chief executive, told Expansão.
Beyond the operator agreements, the venture has received institutional backing from the Ministry of Telecommunications, Information Technologies and Social Communication (MINT TICS), as well as from the information society body Infosi and the small and medium enterprise support agency INAPEM. Araújo stressed that data sovereignty was a central design principle. 'Ping Chat is developed, managed and hosted on national territory — not because a server in Luanda is technically superior, but because jurisdiction over a country's communications data is a strategic asset. Today, almost all of the digital record of Angolan social life is subject to laws that Angola did not write,' he said.
The business model mirrors broadcast media. 'Nobody pays to listen; those who finance the transmission are the advertisers who, in turn, buy the attention of those on the other side' — a dynamic the co-founder describes as a 'broadcast economy'. For brands, the platform creates advertising inventory that reaches a previously inaccessible audience, with payments settled in local currency.
In practice, a user receives 20 pings — one per message sent — for each 20-second advertisement watched. To access the service, a user need only enable the mobile data connection, even without an active internet subscription, in order to begin sending text messages. This is made possible through a protocol WiConnect has established with Angola's two dominant mobile operators, Unitel and Africell.
Araújo argues that every element of the product reflects the realities of the market for which it was built. Global messaging platforms, he says, were optimised for users with abundant data allowances, newer handsets and different consumption habits — a profile that does not fit most Angolan users.
The data-sovereignty argument runs through the startup's positioning. 'Ping Chat is developed, managed and hosted on national territory, in line with the White Paper on Electronic Communications,' Araújo reiterated. 'Not because a machine in Luanda is technically superior, but because jurisdiction over a country's communications data is a strategic asset — and today almost all of the digital record of Angolan social life is subject to laws that Angola did not write.'
Designed to run on entry-level smartphones, Ping Chat intends to expand its feature set over time to include audio messages, images, videos and file transfers — functionalities that bring it closer to Meta's WhatsApp or Russia's Telegram — as user adoption scales up.
