The device you need is a smart card reader.

However, it is likely that you will not be able to succeed even if you have the equipment. The problem is that you do not have access to the areas of the card which hold the data about the mobile network accounts, because you will need the operators secret access keys.

Naturally, no operator will make those keys available, because they open the possibilities of many fraud activities.
