How to set an empty number for telecom mobile phones? If so, how to set it to normal?

There are two ways to set your number to an empty number so that others can call and hear it.

First, use the call forwarding function to transfer the incoming call to an empty number.

1, enter the settings of mobile phone call forwarding function (Android phones are in other settings of call settings).

2. Select the transfer type first, such as always transfer, busy transfer, transfer when no one answers, and transfer when you can't connect. For example, if no one answers, choose to transfer.

3. After selection, you will be prompted to enter the number. You can make up any number, such as 1234, and it must be empty.

But this method can only transfer all incoming calls to this empty number, and it can't be targeted.

Second, use the incoming call firewall software settings.

For example, use LBE Security Master to set the number of interceptions, and then set the interception type to "empty number".

The method is to advance the harassment interception function of Master LBE and define the blacklist first. Add the number you want to block to the blacklist.

Then, set the interception method to "empty number". Master LBE's default interception mode is to intercept blacklists.

In this way, you can set a blacklist or filtering rule instead of transferring all the numbers, which is targeted.

Recommend the second method.
