How to unblock a number

I would recommend you to use LEO Privacy to block unwanted calls so that when you want to remove them from blacklist, you just need to go into LEO Privacy to do this action.

hi Jessica, I tap on "settings" then up the top I tap on "My device" or "device" then scroll down and tap on "call" then tap on "call rejection" or "block calls" then tap on "Auto reject" then tap on the number and that's it.....CHEERS..

Depends on what make and model and OS of phone.
Android phones click on Call ' Settings 'Call Settings 'Call Rejection and edit there

Below are the steps to block and unblock contact.

Block:

Dial a number which you want to block. Click on end call.
From the menu - tap on Logs Icon
Tap on the number which you want to block.
At the bottom - Middle of the screen, You will find three dots (...)
Tap on it.
Tap on Block contact.
A new screen will come - Block Contact.
You will have option to block - Call as well as message.

1) Call
2) Message

Put a check mark and click ok.
It will display the number, by saying it is blocked.

Hi To unblock the accidentally blocked number you need to do the following Press the MENU key Select MESSAGING Scroll down the list and select SETTINGS Select TEXT MESSAGE Select BLOCK NUMBER Highlight the number you wish to unblock and select OPTIONS Select DELETE Select either DELETED SELECTED or DELETE ALL and press OK Briefly press on the ON/OFF button to return to the Main Screen

Go back to that same number you blocked then secarch for the options on that same number you will unblock then you can now unblock the number.

Go to menu then initial setting then call block. Scroll to find the blocked number and choose erase. That erases it from the call block menu on your phone.

just a guess....
search for " screening or block number " at phone/numbers or message/text it may help..
then the rest is up to you..

go to menu, then select settings icon. Scroll to call settings(option 7). Select all calls. go to auto block(option 2). select off, then highlight word Block. Press the OK button on phone to bring up list of numbers that are blocked. highlight the number to unblock, press option and select delete. this will unblock the number and allow them to call you again.

Usually to permanently unblock the number, you need to contact your phone service provider and ask them to unblock your number. You can then block it per call if wanted by dialing *67 before dialing the number.
