struct WorkStruct

    char phone[16];
    char datetime[24];
    char gprsBuffer[64];
    char message[50];
    float temp;
    float hum;
    int oled_modus;

@sn2k Could you try to type "AT+CSQ" manually in Serial Debug mode? See what you'll get. What I got as below,

OK
AT+CSQ

+CSQ: 23,0

That is why it uses Software Serial and his buffers.
