# Find Mobile Phone

> Ask your agent to find a mobile number and explain whether it meets your rule.

[Agent guide: CLI and SDK instructions →](/docs/plays/task-find-mobile-phone)

## 1. Have your context ready

Provide a person’s first and last names. A company domain, email, or professional profile can help establish identity. State that landlines are not acceptable.

## 2. Ask your agent

Paste this into your agent, then provide your task and example inputs when it asks:

```deepline-prompt theme={null}
/deepline-gtm Find a mobile phone number for this person with Deepline. Inspect the maintained phone lookup first and check that my identifying information is sufficient. Require a validated mobile line; do not accept a valid landline. Explain the proposed lookup and applicable usage, then wait for approval before running it. Report the number, identity evidence, line type, validation outcome, source, and any rejection or no-result reason.
```

Complete any requested sign-in yourself. Give the agent the missing information before approving execution. Provider-backed work can incur usage.

## 3. Review the result

The returned number matches the intended person and is validated as mobile. A completed lookup can legitimately have no accepted number. Country information helps normalize a number; it does not guarantee a particular provider route.

Ask your agent:

```deepline-prompt theme={null}
/deepline-gtm Compare the result with the acceptance rule we agreed. Show the evidence for accepted and rejected outcomes, unresolved questions, and recorded Deepline usage where work ran. If work is still running or a response is uncertain, inspect the original saved execution before proposing another request. Explain the next decision I need to make.
```

Approve a larger job, recurring work, or external changes only after reviewing that decision.

## Check your understanding

The agent found a valid landline. Should a mobile-only task accept it?

> **Show the answer**
>
> No. Ask it to retain the rejection, enforce the mobile-only rule, and show
> line-type evidence before accepting a number.
