The broadest Twilio alternative: messaging, voice, video, verification and carrier network APIs under one account, with per-second billing, but the cheapest US calling rates go through sales and its consoles feel spread out.
What it is
Vonage Communications APIs (formerly Nexmo) cover SMS, MMS, WhatsApp, RCS and email through one Messages API, plus voice, video, verification and network APIs such as SIM swap checks and number verification, which Ericsson, Vonage's owner since 2022, exposes through carriers. US list prices: SMS $0.0086 to send and $0.00691 to receive on a virtual number, plus carrier fees; numbers $1.28 a month. Voice bills per second: outbound domestic US calls from $0.00849 a minute and inbound $0.00485, SIP and in-app WebRTC calls $0.00492, toll-free inbound $0.0154; Vonage notes its zone-based US rates need a sales contact. New accounts get free credit. Checked on vonage.com November 13, 2026.
Best for
- Products that need SMS, voice and video from one provider
- Fraud prevention with carrier network APIs (SIM swap, number verification)
- Enterprises already using Vonage's contact center or business phones
What we like
- One Messages API for SMS, MMS, WhatsApp, RCS and email
- A video API alongside voice and messaging, which Plivo does not offer
- Per-second voice billing and carrier network APIs through Ericsson
What to watch
- US SMS at $0.0086 is no cheaper than Twilio's $0.0083 list price
- The lowest domestic calling rates are zone-based and need a sales contact
- Products are spread across several consoles and API generations (legacy SMS API versus Messages API)
- Number rental at $1.28 a month is above Twilio, Plivo and Telnyx
