Simple Phones publishes its pricing; Vapi does not.
Both pages checked by August 19, 2026
- Simple PhonesAI only
- $97/mo
- Basic plan
- Turnkey AI phone answering service for small businesses: Simple Phones generates a starter agent from your business details, assigns a number you forward missed calls to, and their team makes ongoing agent customizations on request rather than you building the agent yourself.
- VapiAI only
- Pricing not published
- no published plan
- Developer platform for building voice AI agents: Vapi hosts the orchestration layer and charges a per-minute hosting fee, while you pick and pay for your own speech-to-text, LLM, text-to-speech and telephony providers and write the assistant, tools and server hooks yourself.
The differences that matter
- Simple Phones offers a trial (Start a 14-day free trial and create an AI agent instantly.); Vapi advertises none.
- Simple Phones publishes prices. Vapi makes you ask.
