Telnyx pricing: SMS, voice and pay-per-call AI
Checked Nov 1, 2026 on Telnyx’s official pages (sources below). Prices change often: confirm with the provider before you buy.
Telnyx is a telecom carrier with APIs for messaging, voice, numbers and AI inference. Its published prices split each service into separate invoice lines: Telnyx’s own rate, plus pass-through fees such as carrier fees or the SIP trunk a call rides on.
Below are the US rates from telnyx.com/pricing/messaging and telnyx.com/pricing/call-control, plus the price per call we read from Telnyx’s x402 route.
SMS and MMS (US, pay as you go)
- Send outbound
- SMS$0.004 per message part + carrier fee
- MMS$0.015 per message part + carrier fee
- Receive inbound
- SMS$0.004 per message part + carrier fee
- MMS$0.005 per message part + carrier fee
Charged per message part. Carrier pass-through fees are listed by carrier on the same page (for example $0.0035 to $0.0045 per SMS part for most large US carriers). Above 100M messages a month, outbound rates step down automatically, for example SMS to $0.0020 per part for the next 150M.
