After you unblocked it, did you restart the phone? You may need to completely remove their contact, power cycle the phone and then add the contact again after they try calling you.
The unblocking feature allows you to remove a phone number from your list of blocked contacts. This means the phone will no longer stop incoming calls, messages, or FaceTime calls from that contact. Once unlocked, the person can send you iMessage messages, leave voicemails, and call you like any other contact.
Scroll down the Settings menu and tap “Phone.” On the “Phone” screen, tap “Call Blocking & Identification.” You can now see a list of all your blocked contacts. To unblock someone from this list, tap “Edit” in the top-right corner of the current screen.
After you unblock a number, the contact will regain the normal capabilities of being able to call and message you. However, you won't receive the messages that were sent when the number was blocked. Similarly, you cannot see call history details for the blocked number after unblocking it.
Alternatively, send a text message from a different number and wait. Messages you send from your blocked number don't appear on the recipient's phone, even though the status says it's delivered. Recipients can only see the messages after unblocking you.
If you are not receiving calls from people that are not in your contacts, then go to Settings>Phone>Silence Unknown Callers and turn that Off. If you are not receiving any calls at all, you need to check Call Forwarding, Do Not Disturb, and other Focus settings.
To turn off, enter this star code
To block a number: Press #, dial the 10-digit number you want to add, and press # to confirm. To unblock a number: Press *, dial the 10-digit number you wish to remove, and press * to confirm. Enter *67 and then the number you want to block from seeing your caller ID info.
If your Android phone is not receiving calls, it can be due to poor network coverage. However, if you can make calls but not receive them, it is likely due to the enabled airplane and DND mode, incorrect network settings, or your device software isn't up-to-date.
No. The ones sent when they are blocked are gone. If you unblock them, you will receive the first time they send something once they are unblocked.
If you block a number you will be unable to receive calls and messages from that number. Once you've unblocked them, their calls and messages will come through on your devices. This only applies to newer messages and has practically stayed the same since Apple introduced the option to block contacts.
Scroll down to Blocked Contacts, and tap that field. You'll see a list of all contacts you've blocked. Swipe left on a contact to unblock it. To unblock multiple contacts, tap Edit (in the upper right-hand corner of the screen) and tap the red circle to remove the number from your Blocked Contacts list.
Your old messages remain blue, but the latest texts you send after they've blocked you turn green. However, the bubble colors aren't accurate clues. They could mean the recipient turned off their phone, gone offline, or switched from iOS to Android.
The only way to see a call history from a blocked number is to unblock the number. They will be added to your regular call list, and you will be able to see any missed calls you receive from the number. However, they will be able to contact you again. Consider if it's worth your privacy.
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.
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.
Blocking Someone on Android Messages and Apple iMessage
When you block a contact over Android or iPhone, they will still be able to send you text messages. These messages will not show up on your phone but the sender will see the messages as sent. They won't know that they've been blocked.
It means either you have been barred from calling that number by either your service provider or the person or the number has been blacklisted on your cellphone.
