Twilio revolutionized the way businesses handle messaging, voice calls, and authentication. With its robust APIs for SMS, voice, email (SendGrid), WhatsApp messaging, and video, it became the backbone for countless apps and services—from Uber notifications to Airbnb verifications.

However, Twilio isn’t perfect for every business. Some users find Twilio expensive as they scale, complex to set up without deep developer knowledge, or overkill for simpler communication needs. In 2025, companies are seeking cheaper, more flexible, or more specialized alternatives to Twilio.

Whether you’re building SMS alerts, two-factor authentication (2FA), customer support bots, or omnichannel marketing campaigns, these are the 10 best Twilio alternatives you should consider.

1. Vonage Communications APIs (formerly Nexmo) – Enterprise-Grade Communication

Vonage offers robust APIs for SMS, voice, video, and verification—very similar to Twilio. It’s highly scalable and trusted by large enterprises for global messaging and voice calling services.

Vonage often beats Twilio on international SMS rates and offers strong documentation and compliance support for industries like finance and healthcare.

Best for: Enterprises, international apps, and companies scaling globally.
Why it’s great: Strong support, global reach, and competitive pricing for non-U.S. routes.

2. Plivo – Cheaper Pricing with Reliable SMS and Voice

Plivo is a cloud communication platform offering SMS, voice calls, and SIP trunking. It’s often cheaper than Twilio while maintaining high deliverability and uptime.

It supports two-way messaging, call masking, conference calls, and local phone numbers in over 190 countries—perfect for scaling SaaS apps, marketplaces, and support systems.

Best for: Cost-conscious startups and apps needing global communication.
Key advantage: Transparent pricing, easy migration from Twilio, and great API documentation.

3. Bandwidth – Direct-to-Carrier Communications

Bandwidth differentiates itself by owning part of its telecom infrastructure (especially in the U.S.), meaning it cuts out intermediaries and can offer better pricing and more direct control over calls, messaging, and 911 services.

It’s often used for large-scale voice and 911 integrations, including services like RingCentral and Zoom Phone.

Best for: Apps requiring call control, SIP trunking, or emergency services.
Unique feature: Direct carrier network = fewer hops = better performance.

4. Telnyx – Programmable Communications with Private Networks

Telnyx offers voice, messaging, wireless SIMs, and even private IP networks for enterprise-grade performance. It’s similar to Twilio but with a heavy emphasis on security, private networking, and programmable voice control.

It’s especially popular among fintech, healthcare, and secure enterprise apps.

Best for: Security-focused apps and large-scale voice applications.
Why developers love it: APIs are powerful but intuitive, with granular control.

5. Sinch – Strong for SMS, WhatsApp, and Video Messaging

Sinch specializes in messaging APIs, including SMS, WhatsApp Business API, MMS, and video messaging. It’s widely used for mobile marketing, customer engagement, and authentication services.

Sinch’s SMS delivery rates and analytics tools are highly competitive in Europe, Latin America, and Asia.

Best for: Businesses focusing on marketing campaigns and customer engagement.
Highlight: Rich messaging across multiple channels.

6. MessageBird – Omnichannel Messaging API for Global Brands

MessageBird offers a full communication platform covering SMS, voice, WhatsApp, email, video, and chatbots across more than 150 countries.

Compared to Twilio, MessageBird is often easier to integrate for omnichannel flows and offers customer service solutions like a unified inbox and automated workflows.

Best for: Brands wanting one API for SMS + email + WhatsApp + Instagram messaging.
Why switch: Seamless multi-channel campaigns without cobbling APIs together.

7. Telesign – Focused on Authentication and Fraud Prevention

Telesign isn’t a general-purpose messaging API like Twilio—it specializes in 2FA, SMS verification, phone number intelligence, and fraud detection.

It’s a smart choice if your main need is secure authentication rather than broader communication.

Best for: Apps needing secure onboarding, fraud protection, and global verifications.
Specialty: Phone-based identity verification and risk scoring.

8. ClickSend – Cloud Communication for Marketers and Businesses

ClickSend provides SMS, MMS, email, voice, fax, and even direct mail through a clean cloud platform. It’s especially easy for marketers and businesses who want plug-and-play solutions rather than complex developer APIs.

It integrates natively with tools like Zapier, Shopify, Salesforce, and HubSpot.

Best for: Non-developers and businesses needing easy communication tools.
Big advantage: No-code integration with marketing platforms.

9. Agora – Best for Voice and Video Calls in Apps

If you specifically need live voice or video communication inside your app (e.g., telemedicine, virtual events, tutoring apps), Agora is a leader.

It provides SDKs for iOS, Android, and web that make it easy to embed real-time voice, video calls, livestreaming, and interactive broadcasting.

Best for: Developers needing real-time audio/video capabilities.

Strength: Strong local presence in emerging markets and truly enterprise-grade tools.
