C-Netz: Generator and Arduino programmer for SIM cards
...
It supports the simple memory cards only. Works only with very early
phones, like BSA51 (tested so far).
An SLE4428 card must be written. The card must not have any protected
serial number area. Also the card must read all 416 written bits via ATR,
not only the first 32 bits.
