hi,
I have a sim800 which is so similar to sim900.
I can send commands to make a call or send a sms or ... .
but although I have used the command "AT+CNMI=1,2,0,0,0" and it will respond "OK", there is no indication when new sms or call. please help me.
I am connected to network, there is no simcard pin, like I said I can make call and get response from the module and I am using pic18f4550 and usart.
