A system uses multiple communication modes for fast uploading of a datum preloaded from a manufacturing device to a data storage device over existing external contacts of the data storage device. Preferentially the data storage device is a high capacity SIM card and a user mode allows communication by standard protocols such as ISO, SD/MMC and USB whereas a manufacturer mode applies a multi data line SD/MMC protocol or a custom protocol for high speed data uploading.
