    This is an update to my recent posting. Good news (and bad news). I was finally able to get the Cellular Shield to connect to the network via the AT+SBAND=7 command. Yipee!

    However, the bad news is that the power LED was bad. I have replaced it with a working SMD LED and I now have a working Cellular Shield with a working LED power indicator. Oooh-rah!

    HELP! After a great deal of noodling around and testing (including swapping my SIM card into another working Cellular shield), I have the following situation:

    1. The power LED is not lighting - even though there is power to the board.
    2. I can send AT+ and AT commands to the board and I get appropriate responses back through the Terminal monitor.
    3. However, I have no signal connectivity and never get a +SIND: 11. I have a quad band antenna on this shield (also just purchased with the board).

    Start of Terminal Monitor Output:

    Starting SM5100B Communication… +SIND: 1 +SIND: 10,“SM”,1,“FD”,1,“LD”,1,“MC”,1,“RC”,1,“ME”,1 +SIND: 3 +SIND: 8 +SIND: 4 SM5100B Communications established… Reading SIM Card Type… +SSIMT: 0,0 OK Reading PIN Value… +CPIN: READY OK Reading/Checking for Signal Quality… +CSQ: 0,99 OK Checking to see if SIM Card Logged to Network… +CREG: 0,2 OK Current DTE indication setting… +CNMI: 3,1,1,0 OK Starting SMS AT commands… OK Sent CMGF Command…

    +CMS ERROR: 313

    Please note that my SIM card works fine in the other Cellular shield that has a working LED power indicator.

    I have a feeling that since the LED is not on, there is a problem with the power regulator on the shield.

    Any help would me most appreciated!
