This is a commonly asked question, but it’s not technically possible for TrapCall to unmask blocked calls received before activating TrapCall on your phone. The service needs to be on your phone at the time of the call for us to work our magic. We offer yearly plans for TrapCall for this very reason, because you never know when you might get a blocked call you really want unmasked.
