@Lehaha maybe that is not PM VM but VM of her previous provider? Can she receive any incoming calls or text at all?
A critical part to porting is to receive a text from the old provider and reply YES within 90 mins. If you fd is not receiving calls and text on PM sim card and can only make outgoing calls, then she might have missed the step and hence porting was not completed
