# VoLTE

> Programmable cellular voice — from a simple second line to enabling native AI assistant on the call.

<Warning>
  **Beta** — VoLTE is in beta. API reference and detailed configuration docs coming soon.
</Warning>

Add a real phone number to any eSIM-capable device. No second phone, no SIP client, no app — just a native cellular line with full API control.
