Meta has changed the pricing structure for businesses using the WhatsApp Business Platform, with the new charges taking effect from October 1, 2026. Each business phone number receives 1,000 free delivered service messages per month; service messages above that allowance are charged on a per-message basis, while utility templates sent during an active customer-service window also become billable. The monthly allowance does not roll over, and automated chatbot replies are counted as delivered service messages, meaning businesses with high-volume customer support or automated interactions may see additional messaging costs.
