WiFi connectivity in South Africa is becoming essential for communities and promising business opportunity. Initiatives to extend affordable internet access are growing rapidly, from urban hubs to rural townships, providing fresh ways to reach users and narrowing the digital gap.
In today's reality, for internet service providers (ISPs), wireless ISPs (WISPs), managed service providers (MSPs) and entrepreneurs, the key question is clear: how can the simple captive portal (WiFi login page) become a valuable marketing tool that attracts users and boosts income?
South Africa’s changing WiFi environment and Starlink era
Public and community WiFi is rapidly expanding in South Africa. For example, Think WiFi manages over 400 hotspots throughout South Africa’s townships and shopping malls, providing 30 minutes of unlimited internet access after users watch a brief ad. Ad-supported approaches like these improve internet accessibility and explore viable revenue options.
Nearly half of South Africa’s urban residents live in townships, controlling billions of rands in consumer spending. However, traditional advertising methods often miss this market. Free WiFi services in townships, in turn, offer marketers a valuable new opportunity. Users connect to the internet by viewing targeted ads, benefiting advertisers and local communities.
Government-backed city WiFi and private initiatives in rural areas are working together to close the digital gap. Regardless of whether access is provided through affordable vouchers or sponsored internet, effectively engaging users at the WiFi login screen is crucial for the financial sustainability of these programmes. A great example is Project Isizwe’s WiCAN WiFi, offering unlimited daily internet for only R5 through neighbourhood shops. Since its inception in 2013, Project Isizwe has collaborated with local and provincial governments to provide free WiFi in low-income communities. This not only improves local internet access but also creates income opportunities for shopkeepers by turning WiFi into both a service and a revenue generator.

While community-driven projects like Project Isizwe have made strides in expanding access in recent years, Starlink, Elon Musk's satellite internet service, adds a new dimension to the country's broadband ecosystem and changes everything. In fact, it has already changed the broadband landscape in Kenya and many African countries.
For many users, Starlink has provided a lifeline, particularly in rural areas where there is little to no fibre infrastructure and inconsistent cellular coverage, which are underserved by traditional internet providers. By subscribing to Starlink’s global roaming packages through resellers in neighbouring countries, South Africans have discovered a workaround to access high-speed internet.
Regardless of the outcome of the latest confrontation between Starlink, operating through SpaceX, and South Africa’s telecoms regulator, ICASA, due to Starlink's lack of a local licence stemming from compliance challenges with equity ownership laws, it is clear that the main battle against Starlink in South Africa lies ahead.
Captive portals can effectively double as advertising platforms for social good and profit
South African ISPs and WISPs walk a fine line between growing their user base and staying profitable, since plain data plans bring razor-thin margins in a crowded field. To keep earnings healthy, many are looking beyond standard bundles to fresh income streams. The fastest-growing model is turning WiFi into an ad-funded service: visitors see an advert on the login page, then browse at no cost while marketers pay for the exposure. This arrangement gives users free internet, boosts advertiser reach and helps providers offset network expenses.
The same idea is spreading to businesses that host guest Wi-Fi. Cafés, malls, airports, clinics, and hotels now expect their network spend to pay its way rather than acting as a simple courtesy. Free access still attracts foot traffic and keeps people on-site longer, yet owners also want to spotlight their own deals, events, and loyalty perks. Without the right tools, though, the captive portal stays underused; a chance lost to address visitors who are literally waiting on that screen before they can surf. An ad-ready splash page turns those few seconds of attention into a direct marketing slot at almost zero extra cost.
Forward-looking South African firms are adapting guest WiFi into their broader marketing plans. Large shopping centres greet users with coupon banners for featured stores, while quick-service restaurants push combo meals during sign-on. Hotels showcase late-checkout offers, spa packages or loyalty sign-ups, and conference venues prompt guests to download event apps. Although full campaign metrics remain private, the trend is clear: sites that pair WiFi access with focused promotions see longer dwell times, higher basket sizes and stronger brand recall. As results stack up, more businesses now view WiFi as a working asset that shifts from a necessary expense into a self-funded, income-generating channel.
Powerlynx: modern solution for WiFi hotspots with built-in marketing campaign engine
Building a captive portal with marketing features is no simple task. Small ISPs and solo entrepreneurs usually lack the in-house talent to bolt ads, data capture and reporting onto a WiFi splash page. They need an easy, scalable solution for managing WiFi hotspot networks with a built-in marketing module from the box, not stacks of custom code.
As disruptive services like Starlink are reshaping access in SA, one of Powerlynx's main advantages is its all-in-one model, which facilitates transforming WiFi hotspots into powerful marketing and revenue-generating tools.
Powerlynx's captive portal offers a built-in marketing campaign engine to utilise collected data from the portal to create and manage targeted marketing campaigns directly. So, you can run for personalised promotions and communication based on user data, enhancing the relevance and effectiveness of marketing efforts.
Feature-wise, Powerlynx provides a no-code splash-page editor. Operators and businesses can brand the login flow with their own colours, logos and wording, then drop in image or video blocks just as they would in a newsletter builder. Because the platform is fully white-labelled (right down to an optional custom domain), end-users never see the Powerlynx name, a detail that matters when an MSP or systems integrator wants to resell the service under its own brand. One dashboard can host hundreds of separate hotspots, each with its own splash page, tariff and hardware mix; a university campus, a chain of co-working cafés or a township WISP can all live side by side without overlap.
The same interface doubles as a marketing console. During sign-on, operators can request anything from an e-mail address to age or gender (everything configurable through custom fields) and then segment visitors on the fly. Those segments power the built-in advertising module, which serves banner or short-form video ads before access is granted and logs every impression and click for later analysis. It can also fire off a bulk SMS without third-party software.
A post-login status page can push personalised coupons, survey links or data-usage reminders, useful for nudging a free user towards a paid top-up. Notifications can be configured to alert users when a bundle is close to expiry or when a voucher balance is low, improving transparency and reducing help-desk calls.
Monetisation options fit several South African use cases. Free access can be offset by the advert engine; paid access can run through card providers familiar to the region (PayFast, DPO or mobile-money gateways) without custom integrations. The voucher generator supports offline sales at a kiosk or tuck shop, printing unique codes that enforce time, speed or data caps once redeemed. All revenue and engagement metrics roll into a single analytics view.
