The lowest-cost Twilio alternative at volume, because Telnyx runs its own network and publishes carrier fees as a pass-through, but onboarding has more verification steps and the bill has more lines.
What it is
Telnyx is a licensed carrier with its own private IP network that sells voice (Call Control and TeXML, its Twilio-style XML), SMS and MMS, SIP trunking, numbers, verification, IoT SIMs and voice AI. Pricing is split into published primitives. Messaging is $0.004 per SMS part to send or receive plus the carrier's fee at cost (Telnyx's own example blends US carrier fees to about $0.0038), MMS $0.015 to send; volume discounts start above 100 million parts a month. Voice is $0.002 a minute for the API plus the SIP trunk: $0.005 a minute outbound and $0.0032 inbound in its US example, so about $0.007 a minute to call out. Local and toll-free numbers start at $1 a month. There is no platform fee and support is included. Checked on telnyx.com November 13, 2026.
Best for
- High-volume SMS or voice where per-unit cost decides
- Teams that want SIP trunking and programmable voice from one carrier
- Voice AI and real-time apps that need low latency
What we like
- About $0.007 a minute for outbound US calls including the SIP trunk
- SMS at $0.004 per part with carrier fees passed through at cost, not marked up
- Owns its network, with SIP trunking, numbers and APIs from one provider and support included
What to watch
- New accounts start restricted: Level 1 limits outbound messages to 50 a day, and international calling, higher send rates and 10DLC orders need extra verification
- Accounts on free email domains created since September 22, 2025 cannot order US toll-free numbers
- Bills split API, SIP trunk and carrier fees into separate lines, so comparing quotes takes work
- Smaller developer community and fewer third-party tutorials than Twilio
