PIC18F4525 - GSM module

[loup-garou]

hi,


i would like to know how to connect PIC18F4525 to a GSM module (SIM300)
(which pins ??) , both of them has I2C and SPI interfaces.


the communication should be in the two directions.

the PIC command the module GSM to dial a number when he get an activtion input, and the module GSM have to activate relays in the outputs of the PIC.


thanks in advance.

SimCom SIM300 is perfect for that

So how does one get hold of these for cheap? I mean most places ask more than what the module itself is worth
