Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Telnyx

  • The advertised per-message price excludes US 10DLC registration fees and carrier surcharges, so American A2P traffic costs more than the rate card row suggests.
  • Support and the partner ecosystem are smaller than the market leader, which matters most during an incident rather than during evaluation.
  • The cost advantage only becomes material at volume, so low-traffic projects save little while giving up ecosystem breadth.
  • Toll fraud controls need configuring properly, because a misconfigured voice account can accumulate serious cost quickly.
  • Product breadth is strong for voice and messaging but thinner for adjacent channels such as video, so multi-channel products may still need a second vendor.

Vonage

  • MMS pricing not published publicly, requires sales team quote
  • International SMS rates can exceed $1.00 per message in some markets
  • Smaller developer ecosystem compared to Twilio

Answered from the vendors’ own pages

Telnyx: How much do per-message rates vary between countries?

By more than an order of magnitude. US A2P SMS is priced in small fractions of a cent per segment, while some international destinations run to several cents or more per message. Always price your actual destination mix rather than a headline US rate.

Vonage: How much does Vonage SMS cost?

Vonage SMS API costs $0.00809 per outbound message and $0.00649 per inbound message in the US. There is no monthly minimum. Virtual phone numbers cost around $4.18 per month.

Source
Telnyx: Are 10DLC fees included in the published price?

No. US A2P messaging requires brand and campaign registration, and those one-off and monthly fees plus per-segment carrier surcharges are added on top of the per-message rate.

Vonage: What is Vonage Voice API pricing?

Voice API charges $0.00798/minute for US domestic calls. You pay per minute for calls made and received via the API.

Source
Telnyx: Why does the private network matter?

Voice quality degrades with jitter and packet loss on the public internet. Carrying traffic on a private backbone with direct carrier interconnects is what the quality claim rests on.

Vonage: How does Vonage compare to Twilio for SMS?

Vonage charges $0.00809 per SMS versus Twilio at $0.0083. Vonage is marginally cheaper for SMS-heavy workloads, while Twilio offers better developer experience and broader channel support.
