Kixie PowerCall & SMS does not offer a permanent free tier but provides a free trial across all four paid plans. The entry-level Integrated plan covers core business phone features including CRM integration, SMS, IVR, call recording, and reporting. Upgrading to the Professional plan adds automation tools like voicemail drop, live call coaching, SMS templates, and Zapier integration. The Power Dialer tier introduces multi-line dialing of up to 10 simultaneous calls with AI human voice detection. The top-tier Power Dialer AI plan adds CRM-synced transcriptions, sentiment analysis, TCPA compliance tools, and custom integrations. G2 reviewers frequently highlight the Power Dialer and local presence features as the primary reasons for upgrading beyond the base Integrated plan.
