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.
It won't turn on a smart USB charger or port.

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, ... )
