LG How to Enable or Disable Call barring

With Call barring on the LG smartphone it is possible to bar calls of a certain category. Both incoming and outgoing calls can be barred. As an example, all incoming calls can be barred if the device is abroad (roaming). It is also possible to create a whitelist, which means that calls can only be made with the entered phone number.

Note: A password (PIN) is required to edit the call barring function, which is set by the network operator; the PIN is usually 0000.
