How to remove MDM from my personal iPhone?

Obviously, your situation is far beyond what users in an online forum can do. I suggest it's time for professional help.

if you have a managed device, contact the administrator that installed the MDM. Apple does not turn off MDM on devices. nothing that you’ve provided in the screenshots indicates that you have a MDM installed.

go to settings > general > VPN and device management

you’ll see any installed management profiles

FYI, the Managed Network named AT&T Passport is installed by your cellular provider. If AT&T is not your Cellular provider, then yours uses the AT&T network. Each provider has their own managed networks used to access additional WiFi features. For example, TMobile uses 2 managed networks, one of them is name TMobile Wingman and is used to access WiFi on some airlines. Xfinity uses Managed Networks to be able to access WiFi from nearby devices where you would normally not have WiFi access. They manage a WiFi network from users routers.

Just wanted to clear that one up for you and that it in no way indicates your device is being managed by anyone else. Removing the SIM card, removes the managed network and when you install a SIM card from another provider, you will see the Managed Networks that they use.

There are many other App Store programs that can take over your devices and spread laterally.

Not possible with apps provided by the App Store. Each app lives in its own Sandbox without being able to contact the others. They cannot spread or install additional apps.

Devices managed by MDM usually have the profile installed at Settings > General > VPN & Device Management, and they can install apps remotely and prevent you from deleting others.

It is possible if you have jailbroken your phone and then there is an alternate App Store where you can find many apps that contain Malware and are no longer protected by the default security provided by your device. Jailbreaking is a deliberate act and not something you would do by accident.

No. There are no such apps.

I am in the exact same situation, I would be very grateful to have someone who can help me out with this issue as I have a few more issues that I have been experiencing with Apple, which I informed them that I was remotely accessed…. Only to be told that it wasn’t under VPN Configurations, so until I discovered hidden (5 devices) in an Apple app, and Family sharing in another app!!!! I was offered a bounty which is cool, I took an oath giving up my privacy rights so the engineers could download the software to find the best solution for my iPhone, stop being cyberstalked, 14 I phones and 22 Androids later, Ultimately I was told if I do not have any way out unless calling my administrator… Um you mean my hacker???????who is a computer programmer and developer/ stalker/ harassment/ law enforcement involved/ FBI…., ??? At the very end now after 15 months of having to deal with an autistic son, move my other child in with grandma and this has hurt our marriage and…… I was told today that there IS NO WAY OUT if I don’t have the passwords to the phones that have had my Apple IDS Changed and since I’m out of luck as they refuse to help me,… tears! Any advice?
