WiFi - Managed networks

As it turned out, my phone service provider told me that it did not have to do with their cellular network, but that I should take the phone in for repair. The phone repair place when I called to ask about making an appointment told me that if it was a managed network that could not be removed, then they wouldn't be able to remove it, so I should instead take it back to the place I bought the phone from.

I did so. Fortunately, at the vendor, someone was able to find the information for me that solved this mystery. It was after all the cellular network provider that had this as a back up system for enabling phone coverage if I was out of area. And the person I spoke with had the exact same thing on her phone. Apparently everyone does that used this cellular provider. I couldn't believe it! I mean I did believe it, but I wished that the person I spoke with at tech support at the cellular provider had known this because this would have saved me a drive. All the same, if anyone else has this issue, and you look under the Settings/General/VPN & Device Management and there are no work or school accounts on your phone, don't sweat, your cellular provider is probably just doing a good job of providing you with cellular coverage and didn't advertise this fact!
