Block someone from calling or texting you one of two ways:
To block someone who has been added to your phone’s Contacts, go to Settings > Phone > Call Blocking and Identification > Block Contact. The All Contacts window will appear where you can scroll through names to then tap the name of the contact you’d like to block. You’ll be taken back to the Blocked window with the name added to the list of blocked contacts.
From Settings, contacts can also be blocked selecting either Messages or Facetime, and then following the above instructions.
In instances where you want to a block a number that isn’t stored as a contact in your phone, go to the Phone app > Recents. Look for the number (or name) you’d like to block and tap the blue “i” with a circle around it to the right of the number. Scroll down to the bottom of the contact card that appears and select “Block This Caller.” The message “You will not receive phone calls, messages, or FaceTime from people on the block list” will appear with two options: Block Contact or Cancel. Hit Block Contact to add the number to the big, bad blocked list.
Block from Messages by selecting the message thread with the contact and tapping the blue “i” in the upper right corner. Tap on their number and then proceed with the same instructions as in the Recents tab in Phone.
Unblock a Contact
Decide an acquaintance served their time on the blocked list and want to digitally revive them? Like adding someone to the blocked list, they can be removed two ways:
In Settings go to Phone > Call Blocking and Identification, where a list of blocked contacts and numbers will appear. Tap Edit in the top right hand corner. Then, tap the red delete button to the left of the name, which will cause a red unblock button appear. Select it, and the contact is restored to unblocked bucket, with all rights, privileges and honors appertaining thereto.
From Settings, contacts can be removed from a blocked list by selecting either Messages or Facetime, and then following the above instructions.
Find the contacts’ name or the number you’d like to unblock in the Recents tab of the Phone app. Select the blue icon to the right of their name, then scroll down and tap “Unblock This Caller.”
Unblock the contact via Messages by selecting the message thread with the contact, and tapping the little blue “i” in the upper right corner. Select the information icon, and proceed with the same instructions as in the Recents tab in Phone.
Will The Contact Know They’re Blocked?
Short answer: no. But a perceptive friend might notice that they can never get a hold of you. When someone in your blocked list calls, they’ll be immediately sent to voicemail. Any message left in voicemail will be put in a separate folder called “Blocked Messages,” to which you can listen.
If the contact tries to send you a text or iMessage, from their end, it will look like the message was sent, though you — thanks to your craftiness — will not actually have to see the message.
Take note, blocking contacts goes one way, meaning you can still call, text, or FaceTime the numbers you’ve listed in Blocked. So if the blocking is also to limit yourself from communication with a certain person, better go ahead and delete their number completely from your phone.
Should you continue to get unwanted phone calls from spammers or marketing companies, consider adding your number to the National Do Not Call Registry.
