In their own words
Bandwidth Messaging API
Bandwidth Messaging API sends SMS and MMS over HTTP, with two-way messaging, inbound webhooks, and options including 10DLC, short code, toll-free, alphanumeric, and global mobile number texting. The product page lists reach in 120+ countries. Traffic monitoring can show unregistered traffic and messages blocked by carriers or Bandwidth, with alerts by email or webhook. Registration Center can autofill customer and campaign data for Short Code and 10DLC; RCS is described as coming soon. Developer guides cover ServiceNow, Zendesk, and Salesforce integrations. New accounts have a default outbound testing limit of 1 message per second, while A2P traffic can go up to the account limit. If a webhook does not receive an HTTP 2xx response, delivery is retried multiple times over 24 hours and then stops. Bandwidth says it does not store message text and retains metadata for queries after successful webhook delivery. Pricing is on request, with a free trial but no free plan. Listed U.S. outbound rates include free for 10DLC SMS, $0.01, paid once for short code or toll-free SMS, and $0.02, paid once for listed MMS routes.
