Short Explanation
The laptop can hear, or it can draw, and it still cannot see. You add a USB webcam. A microphone, a cellular card, and a pen do not put a picture on the call.
Full Explanation
A USB webcam is the camera accessory for a laptop that has none. The user needs video on calls, so the webcam is the accessory. A microphone adds audio only. It does not supply a picture. A SIM is a cellular identity. It is not a camera. A stylus is a pen for a digitizer. It does not capture video. Exam caveat: the call application has to be told to use the new camera. Plugging it in does not always switch the app off the missing built-in device. Operational check: plug in the webcam, select it in the call app, and confirm the other person sees a picture. Select the webcam in the call application and confirm the far side sees video. If the call app still shows no camera, select the USB device by name. Write the result on the ticket before you close it.
