# Can technicians call customers through ServiceTitan Mobile without having a job booked?

## Problem

Technicians need to call customers in the ServiceTitan mobile app without booking a new job.

## Solution

1. Open the ServiceTitan mobile app on your device and go to the **Follow-Up** tab. This is where you can find estimates from completed jobs you are assigned to.
2. Look for the opportunity that belongs to the customer you want to call.
3. Tap **View Opportunity**.
4. Tap **Call** to place a call to the customer. ![Call customer from follow up screen](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/can-technicians-call-customers-through-servicetitan-mobile-without-having-a-job-booked-image-u7a5utqr.png?sv=2026-02-06&spr=https&st=2026-10-31T02%3A39%3A01Z&se=2026-10-31T03%3A39%3A01Z&sr=c&sp=r&sig=pta0usf3VjM5rDfIq7NZ2ZoktTQ4zTNx4Sf15Dkh8go%3D)
