What happens if you block someone?
Incoming calls will go directly to voicemail when someone in FaceTime, Messages, or the Phone app is blocked. They can even leave you a message that will appear silently in the Phone app's Voicemail section but hidden in a Blocked Messages section.
Messages or FaceTime calls will not show on your Apple computers, so the person you blocked is not going to receive a warning or be any wiser. They would be left with the feeling you neglect them.
Blocking others in the mail app will result in their messages going to the specific email address in the trash tab.
View your block list, or unblock someone
You will need to open the Settings app and pick Phone, FaceTime, Email, or Mail from the list if you have a change of heart and delete someone from the block list. Each of the first three selections will have a Blocked Contacts environment, while Mail will have an option to 'Ignore.'
Regardless of which settings page you 're using, when you find the person you want to unblock, swipe over their names to the left.
Your blocked list is the same through Phone, FaceTime Mail, and Texts, so you don't have to visit every device every time and delete the touch. You may remove anyone from the Phone settings page and be excluded (or vice versa) from Calls, FaceTime, and Mail.
