What is Vonage?

Vonage is a messaging api platform built for developers and enterprises building custom communication solutions. It is a different product category from Converge — Converge is a unified inbox for customer-support messaging.

Vonage API pricing in 2026 starts at $0.00809 per outbound US SMS, $0.01446 per minute for US outbound voice (PSTN leg), $0.00410 per participant-minute for video, and $0.0572 per successful Verify call — all pay-as-you-go with no monthly platform minimum (vonage.com/communications-apis/pricing, June 2026). Vonage — acquired by Ericsson in 2022 for $6.2 billion — is a CPaaS (Communications Platform as a Service) provider offering APIs for voice, SMS, video, verify, and messaging, alongside Vonage Business Communications (UCaaS) and Vonage Contact Center. The platform serves more than 100,000 businesses and 1.6 million registered developers.

Converge is a messaging-first inbox at $49/month flat for up to 15 agents. The key difference is product layer: Vonage sells infrastructure to build on (APIs, SIP trunking, UCaaS); Converge sells a finished inbox to use. Per-unit API rates are competitive with Twilio, but the total bill is driven by add-ons (Audit, Auto-redact, Reports, premium support), number rentals, US 10DLC registration, and the engineering time to build a UI on top of the APIs.
