How BAIT Rewrote the Rules
When Walmart launched BAIT in Mexico, the telecom industry paid polite attention and moved on. A supermarket selling SIM cards was not exactly revolutionary. Then BAIT hit 11.8 million active users, captured 36.2% of the MVNO market, and caused Telcel, Mexico's dominant operator, to lose 821,000 subscribers in a single year. Suddenly, nobody was looking away.
BAIT's advantage was never technological. It never built a tower, never laid a metre of fibre, never hired a network engineer. What BAIT had was something no traditional telco could replicate: 2,500 retail locations where millions of Mexicans already shopped every week. SIM activation happened between the groceries and the checkout. Customer acquisition cost approached zero.

Africa Already Has the Infrastructure
The reason this story matters for Africa is that the continent's retail infrastructure is arguably better positioned for this model than Mexico's was. Shoprite operates over 2,900 stores across 12 African countries. Pick n Pay, Massmart, Spar, and Game collectively add thousands more. These are not just stores. They are trusted, high-traffic touchpoints in communities where mobile SIM registration still happens in person.
South Africa already has proof points. Mr Price Mobile, Shoprite Mobile, and Pick n Pay Mobile all leverage their store footprints to acquire mobile customers. Cell C's MVNO client base grew 28% in a single year, with data traffic from MVNO clients surging 127%.
BAIT did not win by building better technology. It won by eliminating acquisition cost. Every Walmart shopper was already a potential subscriber.
Beyond SIM Cards: The Data Flywheel
What BAIT understood, and what African retailers must learn, is that the SIM card is only the beginning. Every mobile interaction generates data: location, usage patterns, spending behaviour, app preferences. For a retailer, this data is transformative. It turns an anonymous basket of groceries into a known, addressable customer whose mobile habits inform personalised offers, loyalty rewards, and targeted promotions.
BAIT offered free WhatsApp data because it knew that WhatsApp was the killer app for Mexico's prepaid majority. The African equivalent varies by market: WhatsApp in West Africa, social bundles in Southern Africa, M-Pesa integration in East Africa. The principle is the same. Price around the behaviour that your customer base already exhibits, and the SIM card sells itself.
The Playbook
For any African retailer with more than 500 stores, the MVNO opportunity is no longer speculative. BAIT has proved the model. The MVNE infrastructure exists. The regulatory frameworks in South Africa, Nigeria, and increasingly across East and West Africa support it. The question is not whether a Shoprite Mobile or a Massmart Connect makes strategic sense. It is whether your competitor will get there first.
