===== Step 2: Install the Profile =====

# Open the **Settings** app.
# Tap **Profile Downloaded** (located right below your Apple Account name near the top).
# Tap **Install** in the top right corner.
# Enter your device passcode.
# Review the warning screen and tap **Install** again to confirm.

===== Step 3: Enable Full Trust =====

# Return to the main **Settings** menu.
# Navigate to **General** > **About**.
# Scroll to the bottom and tap **Certificate Trust Settings**.
# Under the //Enable full trust for root certificates// section, toggle the switch **ON** for your newly installed Root CA, and tap **Continue**.
