sim card interface in a phone

[pes]

Hi,

I was asked to change the sim card slot of a phone.
By removing the old connector broken, I have ripped the track of the
"D-(USB Inter-Chip)" pin. Do you know if the phones sometimes use this
interface to communicate with the SIM card and in what circumstances? In
this case, have you got an idea of ​​the type of circuit that is
connected to this pin?

thank you

I doubt - just for charging, unless there is a camera and then it's for
downloading.

Thank you, but the pin broken isn' t on the USB/charger interface but on
the SIM connector.

I think this interface was designed to accelerate the transfer of files
with the sim card, but these cards haven' t finally integrated many
flash memory and so are not really used to store large files (pictures,
.... )
