A field technician is working onsite where no Wi-Fi networks are available. The technician has a smartphone with an adequate data plan and needs to provide Internet connectivity for a company laptop. Which smartphone setting should the technician enable to share the phone's cellular data connection with the laptop?
Enabling the mobile hotspot (also called tethering) feature turns the smartphone into a small wireless router, allowing nearby devices-such as the technician's laptop-to connect via Wi-Fi and use the phone's cellular data connection. Airplane mode disables all radios, data roaming only affects how the phone connects to cellular networks when outside its home area, and NFC is for short-range data exchanges, not Internet sharing.
