That's interesting, Apple must have changed the policy then. It used to turn itself off after a couple of minutes after being disconnected to save data, battery and security. Certainly, when used over wi-fi, that's still the case.

But don't you lose wifi connectivity if you keep the hotspot on all the time?
Doesn't appear to - when I'm out of the car & the ignition off, the phone reconnects to a known wifi network.

We have two iPhones paired with the car this way & when in the car separately or together the internet connection works. When we are both in the car it chooses to pair with the last known connection although there is a menu option on the car to swap them if required.

Interesting - as soon as I switch personal hotspot on my X, it disconnects wifi and just goes to 4G (just tried it now sat in the house).

Do you have the Bluetooth still switch on ? (doesn't need to be connected to anything).

Also when you are on the Hotspot Settings screen the phone is disconnected from your WiFi - once you back out to the main settings list it reconnects after four or five seconds.

I'm using an iPhone 7 plus & iPhone 8 plus iOS 12.1 (just about to update to 12.1.1).

So just tried it again (I always leave Bluetooth on) and about 5 mins later it reconnected to WiFi.

However it disconnected a minute later then reconnected. Ios12.1.1 for me. So learnt something new but a little flaky - but would give it a go if I didn’t have the sim.

Cheers

Like Senwar I always leave Bluetooth on.
Like Senwar I’ve learnt something new!

Yes, the WiFi does return once I’ve exited back out to the home screen - thanks mss911. Next thing to try would be whether the tethering works (by WiFi or usb) while the phone is being used for CarPlay.
