Messaging is live on Bandwidth Build

October 13, 2026
Messaging
API
Universal Platform

Bandwidth Build now supports a 30-day free trial of SMS. Send and receive messages between your verifiable mobile number and a Bandwidth Build 10DLC phone number through the same Messaging API our enterprise customers run on.

Send your first SMS message from the UI with just one click; respond from your phone and watch the reply come back to you in real time. When you’re ready to reach real customers, upgrade to the full Bandwidth App portfolio.

Bandwidth Build free trial includes 3,000 credits which you can use toward sending messages in addition testing voice capabilities available in Build, such as SIP trunking, inbound and outbound calling, IVR and call flows, and call recording and transcription. And when you upgrade to a full Bandwidth account, your integration comes with you. It’s all built on the Bandwidth Universal Platform, no rework required.

This free trial experience is for SMS for US and CA users only. Build users are not yet able to create their own campaign or send messages to other people. 

Learn more in the dev docs. 

Sign up at bandwidth.com/build-sign-up, or ask an AI assistant to create an account using the Bandwidth CLI.
