Hi Brian_7, When you did smscon -imsi (with your fathers card inside) you did 'learn' smscon that this card is trusted so after this when ever you insert this card in a later time again is NOT seen as a possible card from a thief. I don't have a explanation why smscon didn't send a SMS to your mother's card the first time your fathers card was inserted (it should have). Maybe Saturn's remark has some validity...
