If you want to delete the blocked contact list for phone calls, go to Settings> Phone>
Blocked numbers will be visible in the Blocked section (iPhone and KaiOS) or Blocked contacts section (Android) of your WhatsApp Settings. The only way to remove blocked contacts from this list is to unblock them.
If I block someone on my phone and then delete their number, are they still blocked? Yes, you can try and see. Deleting a blocked number will only remove the blocked contact's details like name and address, etc .. However it will remain in the blocked list as a phone number.
When you block a number, it automatically blocks all incoming calls and messages from that number and also deletes all of the conversations you have had with them. This is so they won't be able to reach you at all and no matter what they do.
When you block a phone number or contact, they can still leave a voicemail, but you won't get a notification. Messages that are sent or received won't be delivered. Also, the contact won't get a notification that the call or message was blocked. When you block an email address from Mail, it goes to the trash folder.
Yes the block/unblock phone number list will remain on both iPhones since they use the same Apple ID.
There is no way to see missed calls from blocked numbers on an iPhone. To see if you missed a call from a blocked number, you need to unblock them or contact customer service. Once you unblock, you can check to see if you received a voicemail from a blocked contact.
There is no limit.
Related. On an iPhone running iOS 7 or later, you can finally block the phone number of a nuisance caller. Once blocked, the phone number remains blocked on the iPhone even after you delete it from your Phone, FaceTime, Messages or Contacts apps. You can confirm its sustained blocked status in Settings.
Blocked text messages disappear
When someone that you've blocked texts you, their texts go nowhere. They won't receive any notification that they're blocked, and their messages will still look like they've been sent. But you won't receive any of them, and you can't respond.
Android phones move all blocked messages into a folder on the phone called “Spam and Blocked.” That means that the phone is still collecting messages from the blocked people; they just aren't notifying you. This can be a lifesaver in needing those blocked messages for various reasons after the fact.
If you've been blocked, the recipient will not receive a notification and won't be able to respond. If you don't receive a returned call or text message within a few days, there's a good chance you may be blocked.
When you call a number that has blocked yours, you may hear one or half a ring or no rings at all and then the call will go to voicemail. If it goes straight to voicemail, their phone may also be off or out of range, or they may have temporarily turned on Do Not Disturb mode to work, drive, or sleep.
To delete your spam messages, open the Messages app. From the main window, tap the menu button and then tap Spam & Blocked (Figure A). The Messages menu is accessed from the application main window. In the Spam & Blocked window (Figure B), you'll have to manually tap every single message you want to delete.
Generally speaking, it is not possible to restore blocked texts on iPhone 7 or other iPhone models, because there is no blocked folder on iPhone to save messages and texts that are stopped from receiving. It means that no blocked messages are saved on your iPhone.
