Those of us who are no longer paying customers of twc/spectrum can no longer get help from twc/spectrum, we do not have service accounts and our credentials no longer work. This is why many people over the years have been coming to Apple for help. There are many threads here that have become locked with no solutions.
A company that is advertising itself as the privacy/secure phone product in its latest marketing campaign has allowed these "profiles" to linger on our devices even though we delete the profile, delete the two/spectrum apps, "forget" the wifi networks, yet when we go to restaurants, doctor's offices, and businesses near spectrum wifi locations we get spammed by Apple iOS prompting us for a password.
I've even logged into my Mac to ensure there is no spectrum/twc/cable wifi and similar SSID in my apple profile's list of all the SSIDs I've ever connected to and there is none there, yet Apple iOS still interrupts us and prompts us for a password for a service/application/profile/SSID which we have already removed.
Others have reported here that reset network setting have not worked, and others have reported that full phone reset and restore's have brought the settings back.
Apple's programming has allowed that settings removed by the user are not truly removed.
Full phone resets without a phone restore are not an acceptable solution.
