Hi Folks,
I'm new to this so please forgive my lack of knowledge.
Basically I am trying to send an SMS from the simcard (using AT commands and a SIM eval kit) . I have put the simcard in a normal mobile phone and cancelled all passwords etc - entered a phone number in the contacts and stored a message on the simcard but when I try send a saved SMS using AT+CMSS=1 I get error 302 or other ways I get error 515. Any advise?
Thanks
Do you think that means it is not possible to send an SMS which is stored on the sim card?
Basically what I was trying to do was to send an SMS to the eval kit (sim340) then get it to send it back to the sender using AT commands. Am I trying to do the impossible?
I have a eval kit like yours and the first time that I have used it I could not send msg. the solution was to change the simcacrd and to put that of another phone company. Make sure that your simcard is unblocked.
Send AT+CPIN? if responded +CPIN READY means simcard unblock, if responded +CPIN:SIM SIM you should introduce the pin number sending AT+CPIN=nnnn (nnnn is pin number).
