Nigeria-China WhatsApp Messaging Expansion

I want to extend my customer communications from Nigeria to China and need support from someone who works comfortably with both WhatsApp Business and the official WhatsApp API—experience in both areas is essential. Your mission is to set up (or connect) a fully compliant WhatsApp Business/API environment that can send and receive messages to Chinese numbers while operating from Nigeria. T Concrete deliverables: • A live, policy-compliant WhatsApp Business or API instance capable of reaching Chinese users. • Step-by-step documentation of every configuration action, keys, and approval obtained. • A short hand-off session so we can manage, scale, or troubleshoot independently. When you reply, outline: • The infrastructure or BSP access you already have. • Expected timeframes for number verification and go-live. • Any third-party fees we should budget for. • Your pricing—fixed, milestone, or usage-based—so I can compare options quickly. Only legitimate routes and solutions will be considered; SIM banks or grey paths will be rejected outright. I aim to shortlist partners this week, so please include your availability along with the details above.
