What Ribbit services can I use for free?
You must first establish a billing relationship with Ribbit to test or enable the following existing and scheduled features: International calling, voice-to-text transcriptions, two-way text SMS messaging, interactive voice recording (IVR), conferencing, and more. However, you can stil use basic Ribbit platform services (contact management and domestic calling) if you choose not to establish a billing relationship with us at this time. This is enough functionality to create a simple application such as a product review wall, a personal contact management app, or an 800-number “call-me” button.
