## Direct answer

SMS should behave more like a protocol because developers and agents need predictable interfaces, stable identity, delivery visibility, and safety controls. TextTree wraps SMS in programmable APIs, webhooks, logs, numbers, and controls so it feels more like infrastructure than a legacy telecom portal.

## Best for
