Connect to a Personal Hotspot with a USB cable
You can connect a Mac or Windows device to the Personal Hotspot on your iPhone using the USB cable that came with your iPhone (or another cable that matches the ports on your iPhone and other device).
Note: If you see an alert on your iPhone that says Trust This Computer? tap Trust. You may be asked to enter your device passcode to proceed. If you see an alert on your Mac that says “Allow accessory to connect?” click Allow.
As soon as it’s connected by a cable, your Mac or Windows device is able to use the cellular connection on your iPhone.
