What is Bandwidth?

Bandwidth is a US-based communications platform that owns and operates its own nationwide IP voice network rather than reselling capacity from other carriers, offering Voice, Messaging, and Emergency Calling APIs to developers and enterprises.

Pricing is usage-based, billed in 6-second increments for voice, with outbound SMS starting around $0.004 per message and domestic outbound calls around $0.010 per minute. Bandwidth's Emergency Calling API connects to more than 6,000 public safety answering points, making it a common choice for enterprise and telecom-grade communications needs.
