hi everyone,
i'm using gsm shield to receive sms which is then stored in an array but code is working but the word OK is display each time i'm receiving sms, can someone please help me how to solve this.
Please refer to the attachment for the error i'm encountering.
Thanks a lot
/*

This sketch, for the Arduino GSM shield, waits for a SMS message
and displays it through the Serial port.
Circuit:
* GSM shield attached to and Arduino
* SIM card that can receive SMS messages
