I have an iPad Air WiFi, and was recently on a remote island that had a, can I call it, a "Cellular Data tower," which I believe is commonly called a 'hotspot.' The island had only private WiFi service. So I was out of contact with the 'Net. I was very surprised when, at a restaurant which had WiFi now & then the Personal Hotspot icon appeared on my status bar. I do not know why that happened; maybe something to do with management's tech setup? Can I configure an iPad Air WiFi model to connect to the 'Net if a hotspot is in range? The User Guide (p.58) says a WiFi iPad *can connect to the 'Net but it must be connected to the cellular data network. How to do that?? I went to Settings, searched "Cellular Data," and one result was "Safari->Reading List." I went to Safari, there was no 'reading list.' So I don't know if I get my machine configured to connect to the hotspot or not. Does anybody know? Another guy on the island had a Samsung laptop, and he had a little machine (he didn't know the name for it) which just needed to be near his laptop, cost $75, Huawei, I've attached a pic of it here so he was online because of it. It would fit in the palm of your hand. Does anyone know (if I can't connect just with my WiFi machine) what that thing in the photo is and do they make them for iPads like mine? Thanks for reading!
