Most providers bolt WhatsApp on as a separate channel with separate numbers and billing. Telnyx runs WhatsApp messaging and calling on a single Telnyx number alongside PSTN, SIP, and SMS. One API, one dashboard, one bill. The Meta per-message fee is the same with every provider, so the real difference is multichannel consolidation and AI. ### Can I use the same number for WhatsApp and my existing Telnyx services? ### Can I put an AI agent on WhatsApp calls? ### How much does WhatsApp cost on Telnyx? ### How long does it take to get started? ### What countries are supported? ### Is AI on WhatsApp messaging available? ### Can I use my existing WhatsApp number? ## Sign up and start building [Talk to an Expert](https://telnyx.com/contact-us)[Sign up](https://telnyx.com/sign-up) [Start building](https://telnyx.com/sign-up)
