I have a Droid phone. When my internet is down I turn on my hotspot and connect my laptop to the phone's hotspot. For this to work I need to turn off WIFI so my phone uses cellar connection. If I keep WIFI on, the phone tries to go out the WIFI which does not have internet.
I have been told that this configuration does not work with an IPhone. You need to keep the WIFI on or the hotspot will not work.
How can the IPhone hotspot work if it is connected to WIFI that does not have internet access? Does the IPhone realize there is not an Internet so it knows to go out the cellular connection? Why would it not work if WIFI is off?
