Dear All,

Please help me.
My problem: SIM_VDD = 0, not found network, SIM card doesn't work.

I connect SIM300CZ with SIM Card as below:

SIM Card..............................SIM300CZ
C1------------------------------>SIM_VDD
C2------------------------------>SIM_RESET
C3------------------------------>SIM_CLK
C5 -->> GND
C6 NC
C7------------------------------->SIM_IO

between C1 and C7: R 10k
between C1 and C5(GND): C 200nF

Thanks.
