Dear Sirs,
I had already tried
$ mkdir /media/sim
$ sudo mount /dev/sdc /media/sim
But this doesn't work, as I don't know the filesystem of the card.

Your reader is a TF/SD/MMC card reader from what I can see, it reads various types of memory cards. A SIM card is a smart card and not a memory card/mass storage device and smart card are accessed serially using the ISO7816 communication protocol. The internal file system is not accessible for mounting, instead there are serial 5 byte commands for selecting a file and commands for reading/erasing/writing the file you have selected.
