## Summary

Robert Hamblet, CEO and co-founder of Teal Communications, explains how his company provides a neutral eSIM credentialing and connectivity management platform to solve the fragmentation in the IoT connectivity market. He details the technical differences between operator-locked, MVNO-arbitrage, and neutral platforms, emphasizing the need for programmable, dynamic credential access for global IoT scaling. Hamblet discusses specific use cases in mobility, health tech, and industrial sectors, highlighting challenges like data sovereignty in countries like Brazil and the technical distinctions between NB-IoT and LTE-M for low-power devices.
