SIM300 general help
+CPIN: NOT INSERTED
mean that the sim card is not, or probably "not well" inserted. Try to clean the contacts, and keep the card pushed by hand, just for test.
+CPIN: SIM PIN
pin code must be entered, try AT+CPIN=1234
+CMS ERROR: 517 : SM BL NOT READY
sm stay for Sim Phonebook. Anyway this message probably mean that the sim is not well inserted, or that the PIN code in not inserted (try AT+CPIN=1234 )
Receiving bad charachters on the terminal:
This is due to the fact that Sim300 start up as factory default in "autobaud rate". Set it to a fixed speed, for example AT+IPR=115200
The speed will change after the "OK".
