In São Paulo, we directly addressed the challenges of the complex networks and volatile delivery rates in the Latin American market. We demonstrated a deeply integrated SMS channel with local carriers, achieving a delivery rate exceeding 99% in key markets such as Brazil, Mexico, and Argentina. This performance attracted the attention of numerous local payment platforms and online entertainment companies. Through the exhibition, we not only gathered a wealth of precise demand data but also successfully developed two leading Latin American online transaction platforms into pilot clients.
