I'm going to be using the GE863 module in an upcoming project. I can't seem to find enough information on connecting a SIM card to the GE863 though.
So far all I could find was the following pin descriptions for the SIM socket:
VCC (C1)
Reset (C2)
CLK (C3)
GND (C5)
VPP (C6)
I/O (C7)
On the GE863, five of the six SIM connection pins are obvious (VCC, RST, CLK, GND, I/O). This would leave me to assume that the SIMIN pin on the GE863 gets connected to VPP on the SIM card, but we all know what happens when we assume.
So... could someone point me in the right direction here? Schematics of the GE863 wired to the SIM socket would be great, but any sort of clear indication will do.
Thanks
