How to troubleshoot failed SMS delivery with your AI

Connect CallFire to your AI client once. From there, your agent handles the heavy lifting of digging through logs to find out exactly why a message failed.

Ask AI about this page

Short answer

Why did my SMS messages fail to deliver?

Your AI can cross-reference failed message logs against your contact list to spot invalid numbers or carrier-side blocks. This identifies whether the issue is a bad recipient or a filtering problem. You'll get a clear list of problematic entries and the specific reasons for each failure.

Where every issue lands.

Troubleshooting outcomes

The AI sorts your delivery failures into actionable categories.

INVALID

Bad phone numbers

The AI identifies contacts with incorrect formatting or disconnected lines. You get a list of numbers to remove from your database.

BLOCKED

Carrier filtering

The AI flags messages caught by carrier spam filters. You'll see which specific content or patterns triggered the block.

RETRY

Temporary issues

The AI catches transient failures like network congestion. These are the messages you can safely attempt to resend later.

MANUAL

Human review needed

The AI highlights ambiguous errors that require you to check your messaging strategy or carrier settings manually.

The workflow

What your AI does when the failure occurs.

Instead of you clicking through dashboards, your agent pulls the data and finds the patterns.

  1. Pulling logs

    The AI pulls your recent messaging history to see which specific texts failed to send.

    list_texts

  2. Inspecting failures

    The agent looks at the specific error codes and status of each failed message.

    get_text

  3. Checking recipients

    The AI pulls the details for the specific people who didn't receive the message.

    get_contact

  4. Auditing the list

    The agent scans your entire contact directory to find patterns in invalid numbers or opt-out statuses.

    list_contacts
