    sim300s - KUNS Design - GPRS+GSM SIM300 Module+Development Board not registering?

    Just to clarify, AT+COPS? - Should not be empty correct? And AT+CSQ - should provide something other than 99,99 correct? (I'm in an area with great service when the sim is in my phone) --I have this nice tool setup, https://m2msupport.net/m2msupport/module-tester/ pretty nice. Thank you
