I do not yet own an Ipad and I have no experience with using a cellular Ipad as a hotspot. Most of the time the Ipad will be used as a normal tablet, but there will be stretches of time, ie while traveling, that it's primary purpose will be as a hotspot for other devices. My question is this when using it as a hotspot, I assume I should have it plugged in at all times, but does it have to be turned on or can it be in screen dark mode, what I call sleep mode, for it to act as a hotspot. Any information about how to use the Ipad as a hotspot would be helpful, I understand how you set it up in Settings, what I don't understand is what state you leave the Ipad in 24 hours a day?
