Block somebody, then unblock them. It’ll randomly block them after unblocking them. So I removed it, reinstalled, and now I can’t use it without starting a free trial, that means after you signup, you have to go into the App Store or whatever, and cancel the subscription, so it doesn’t charge you in seven days. Did I have to do that the first time? Didn’t want to do it again, so I removed it.
You might want to go to Phone in Settings, and blocking services, and disable it before removing it.
Call Control doesn’t require setting up a subscription. It has neighbor spoofing blocking too, the only thing I care about.
