How Does It Work? - Flexispy

Simply make a call to the phone whenever you want to secretly listen through its microphone. The target will not ring or show any signs of an incoming call, but will answer and turn on the mic immediately. No record of this call will be left in the call logs. Safely, discreetly and remotely. Send another hidden message to turn the feature off, when you want to place a normal call that will ring again.
