Hi
here some general info regarding sim card protocol

Card Power-Up

When a smart card, or in our discussion SIM card, is inserted into a card reader or mobile
handset the card is not immediately powered up. Doing so without out at first testing if
the card is properly inserted can destroy the card.

Once the proper insertion of the card has been detected, the card accepting device (CAD)
or mobile equipment (ME) the CAD or ME first powers the card to a normal operating
voltage and the card is brought to an idle state. Then a RST command is sent over the
contact line (C2) on the face of the SIM card. The RST command remains in a low state
for a set period of time and then is set to a high state. This is a signal to the SIM card to
begin its initialization sequence.

but this is a theoretical frame.
let me know the present condition of the hand set without
RST pad damaged
regards,
NEIL
