I got hold of a used Dell mini 9 with xp. I have a 'sim not found' problem when trying to connect to vodafone or using the dell mobile wireless utility. I have seen the dell service pages that shows you how to take the machine apart and noticed that the wireless 3g card is seperate from the sim reader. Has anyone had this problem and changed the wireless 3g card with positive results. Just wondering if the sim reader could be at fault and not the card as the device manger finds the hardware and all drivers are present.
