# SMS

> Understand where SMS fits in TruAgents and what setup and operational behavior make it different from email.

## Summary

SMS is the shorter, faster, more constrained communication channel in the TruAgents model.

Compared with email, it generally asks for tighter message design, simpler formatting assumptions, and channel-specific infrastructure setup.

## Who this is for

Teams planning how to use TruAgents across one or more communication channels.

## What makes SMS distinct

* shorter message expectations
* stronger sensitivity to delivery setup
* direct links to phone-related contact data
* provider-specific setup requirements

## What "SMS ready" should mean

Before trusting an SMS campaign, the team should be able to say:

* the provider credentials are configured correctly
* the originating phone number is configured
* contact phone data is usable
* the campaign message is short and clear enough for the channel
* the team understands how replies and follow-up should be handled

If one of those is uncertain, the channel may exist in the app without being operationally ready.

## Current product hints

The current app suggests that SMS setup is closely tied to Twilio-style credentials and a configured originating phone number, which means this channel should be documented as both a communication choice and an infrastructure choice.

## How to think about SMS in TruAgents

SMS belongs inside the same campaign and communications model as the other channels, but teams should still be more conservative about:

* message length
* field readiness for phone numbers
* provider setup and credential completeness

## When SMS is the right channel

SMS is usually strongest when the team needs:

* short, direct communication
* fast response loops
* less formatting complexity than email
* clear phone-based contact data

It is usually a poor fit when the message needs heavy context, complex formatting, or a long structured explanation.

## Common mistakes

* treating SMS like compressed email
* assuming provider credentials are enough without a real sending number
* overlooking contact phone quality
* testing campaign logic before SMS infrastructure is stable
* forgetting that short messages still need clear review and intent
