Using your iPhone 14 Pro is a breeze. To turn it on, press and hold the side button. When taking photos, just open the camera app and tap the screen to focus. You can switch between different lenses for various effects. For Face ID, make sure your face is clearly visible to unlock the phone. When it comes to charging, use the recommended Apple charger to avoid any issues. Keep your iPhone in a cool, dry place and avoid exposing it to extreme temperatures. Clean the screen with a soft, dry cloth. Regularly update your iOS to get the latest features and security patches. And remember, since it's unlocked, you can easily switch carriers whenever you want.
