The Apifonica Voice SMS Messaging API allows developers to integrate SMS sending, receiving, processing, and tracking features. It's available with a token as the authentication method and JSON format for callbacks. With the API, users may benefit from worldwide reach, Unicode characters, two-way SMS, delivery status notification in real time, and SMS concatenation. Developers can start for free and if they need additional calls, they can contact sales at email@example.com
