GoHighLevel SIM-Based Calling Setup Guide

If you use ClickUp or other tools to manage your agency, you can still rely on the GoHighLevel mobile app to place calls that show your business number instead of your personal cell. This guide explains how SIM-based calling works in the app and how to configure it so your outbound calls are tracked properly while protecting your personal caller ID.

The steps below are based on the official GoHighLevel documentation and walk you through enabling SIM-based calling, understanding its behavior, and troubleshooting common issues.

What Is SIM-Based Calling in GoHighLevel?

SIM-based calling in GoHighLevel lets you use your phone’s native dialer while still logging activity inside the CRM. You call leads and clients using your normal cellular service (your SIM), but the system routes the call in a way that displays your GoHighLevel business number to the contact.

This option is useful if:

  • You want more reliable call quality via your carrier network.
  • You prefer the native phone app experience.
  • You still need calls tracked in GoHighLevel as activities.

SIM-based calling differs from in-app VoIP calling, which uses data or Wi‑Fi directly inside the GoHighLevel mobile interface.

Key Requirements for GoHighLevel SIM-Based Calling

Before turning on SIM-based calling, review these basic requirements so the feature works correctly in your GoHighLevel account.

  • You must have the GoHighLevel mobile app installed and logged in.
  • Your account or sub-account must have at least one phone number assigned.
  • Your mobile device needs a working SIM with active cellular service.
  • You must grant the app permission to access phone and contacts (if prompted).

Once these items are in place, you can configure SIM-based calling from the mobile app settings.

How to Enable SIM-Based Calling in the GoHighLevel App

Follow these steps to turn on SIM-based calling and link it to your GoHighLevel number.

Step 1: Open the GoHighLevel Mobile App

  1. Unlock your smartphone.
  2. Locate and tap the GoHighLevel mobile app icon.
  3. Sign in with your account credentials if you are not already logged in.

Make sure you are in the correct sub-account where your business phone number is set up.

Step 2: Access GoHighLevel Phone Settings

  1. Inside the GoHighLevel app, open the main menu or profile menu (usually in the top corner).
  2. Navigate to the section labeled Settings or Phone, depending on your app version.
  3. Look for an option related to Calling or SIM-based calling.

The exact wording can vary slightly, but you should see an option that refers to using your device’s SIM for calls.

Step 3: Turn On SIM-Based Calling

  1. Tap the SIM-based calling option to open its configuration screen.
  2. Enable the toggle or checkbox labeled something like Use device SIM for calling.
  3. If prompted, select the GoHighLevel phone number that should be displayed as the caller ID for your contacts.

After enabling this option, outbound calls initiated from the contact record screen in GoHighLevel will use your device’s phone app while still passing through your system number.

How GoHighLevel Handles SIM-Based Calls

When SIM-based calling is enabled, GoHighLevel coordinates between your CRM and your phone’s dialer.

  • You initiate a call from inside the contact view in the app.
  • The system triggers your native dialer using your SIM.
  • The call is logged as an activity in the GoHighLevel contact timeline.
  • The contact sees your GoHighLevel business number, not your personal mobile number.

This creates a balance between reliable carrier calls and centralized call tracking.

Call Logging Behavior in GoHighLevel

With SIM-based calling turned on, GoHighLevel typically records:

  • The date and time of the call.
  • The direction (outbound from you to the contact).
  • The contact associated with the call.

Use your contact’s activity timeline to verify that calls are being logged correctly after configuration.

When to Use GoHighLevel SIM-Based Calling vs In-App Calling

Both calling options inside GoHighLevel have advantages depending on your workflow and connectivity.

Use SIM-Based Calling When:

  • You have strong cellular coverage but weaker Wi‑Fi or data.
  • You prefer your phone’s native call interface.
  • You want to minimize dropped VoIP calls.

Use In-App Calling When:

  • You have strong Wi‑Fi and limited cell minutes.
  • You manage most conversations through the GoHighLevel app and want to stay fully in-app.
  • You’re working from a device without a traditional SIM (like some tablets).

You can switch between SIM-based calling and VoIP-based in-app calling as needed in your GoHighLevel settings.

Troubleshooting GoHighLevel SIM-Based Calling Issues

If SIM-based calls are not working as expected, try the checks below before contacting support.

1. Verify Permissions

  • Ensure the GoHighLevel app has permission to initiate phone calls.
  • On your device, open system Settings > Apps > GoHighLevel and confirm call permissions are enabled.

2. Confirm Your Business Number

  • In your GoHighLevel sub-account, verify that a phone number is assigned.
  • Make sure the correct number is selected in the SIM-based calling configuration screen.

3. Test a Call from a Contact Record

  1. Open any test contact in GoHighLevel.
  2. Tap the phone icon to start a call.
  3. Confirm that your native dialer appears and that the call is connected.
  4. Ask the recipient which number is displayed to verify your GoHighLevel number is showing.

4. Check for App and OS Updates

  • Update the GoHighLevel app to the latest version from your app store.
  • Make sure your mobile operating system is reasonably up to date.

If you still have issues, review the official SIM-based calling guide at this GoHighLevel support article or contact your account administrator.

Best Practices for Using GoHighLevel SIM-Based Calling

To get the most from SIM-based calling in GoHighLevel, apply these practical tips across your team.

  • Train your team: Show users how to start calls from the contact record instead of the native dialer alone.
  • Monitor call logs: Regularly review contact timelines to ensure calls are being tracked properly.
  • Standardize caller ID: Use a single shared GoHighLevel number for outbound calls in each sub-account for consistent branding.
  • Document your process: Add internal SOPs in your favorite project management tool so everyone follows the same GoHighLevel calling workflow.
