# Activating the 3CX Mobile App with a QR Code

**Before You Start Activating 3CX** **Make sure you already have:**

- The **3CX Mobile App** installed on your smartphone.
- An active 3CX extension account.
- An activation QR Code from your administrator or from the 3CX Web Client.
- A stable internet connection.

# Step 1: Install the 3CX App

To activate the 3CX Mobile App with a QR code, you first need to install the 3CX app. You can install it from:

- **Android:** Download it from the Google Play Store.
- **iPhone (iOS):** Download it from the App Store.

Once installed, open the **3CX** app.

## Step 2: Get the QR Code

After installing the app, the next step to activate the 3CX Mobile App with a QR code

is to get the QR Code, which you can obtain in two ways.

- **Via the Welcome Email**

Your administrator usually sends an email containing your account details along with an activation QR Code.

Just open that email and get the QR Code ready to be scanned.

- **Via the 3CX Web Client**

If you can already log in to the Web Client:

1. Log in to your 3CX Web Client account.
2. Click the **profile icon** in the top right corner.
3. Select the **Scan QR Code** menu.
4. The QR Code will appear on screen.

### Step 3: Scan the QR Code

1. Open the **3CX Mobile App**.
2. Select **Scan QR Code**.
3. Allow the app to access your camera if prompted.
4. Point your camera at the QR Code.
5. Wait a moment for the process to complete.

Once successful, the app will automatically connect your smartphone to your 3CX extension.

## Step 4: Confirm the Activation Was Successful

If activation succeeds, you'll see:

- Your name or extension number appear in the app.
- The status change to **Available**.
- You can already make and receive calls using your office number.

## If the QR Code Won't Scan

Here are a few things you can try:

- Clean your camera lens.
- Make sure there's enough lighting.
- Enlarge the QR Code display if you're opening it on a computer.

## If You See an "Invalid QR Code" Message

If you see the message **"Invalid QR Code"**, the QR Code has likely expired or doesn't match your account. Contact your administrator to get a new QR Code.

## Scan Was Successful, But You Still Can't Receive Calls

Make sure:

- Your internet connection is stable.
- The app's status is set to **Available**.
- 3CX app notifications are turned on.
- The app isn't restricted by battery-saving mode.
