Sabesp, Vivo and Idemia deploy 4.4M smart‑meter IoT project in São Paulo
What happened
Sabesp announced a 14‑year programme with Vivo and Idemia Secure Transactions to connect 4.4 million smart water meters in São Paulo City and São José dos Campos, describing the initiative as the world’s largest IoT connectivity project for water metering. The deployment uses Idemia’s eSIM/iSIM IoT platform (stated to be GSMA SGP.32‑compliant) to deliver hourly consumption data, leak detection and network optimisation via cellular IoT connectivity.

The Atomic Take
This deal highlights how large utilities are buying end‑to‑end connectivity bundles rather than just SIMs: MNOs can win by combining scale, coverage and integration capabilities while third‑party eSIM/iSIM platforms take on profile management and device security. For MVNEs/MVNOs that serve enterprise and vertical markets, the commercial opportunity is to offer certified eSIM orchestration, lifecycle management and SLA‑backed connectivity packages that meet utility security standards (SGP.32) and evolving post‑quantum requirements.
