    Arduino gps / gsm / gprs sim problem

    Hello, I am just looking for some advice, I recently purchased: SIM808 GPS/GPRS/GSM Arduino Shield(Product Code : RB-Dfr-665) {https://www.dfrobot.com/product-1469.html}, but I have not been able to collect any GPS data? I am getting the "Open the GPS power success" in the serial terminal when I connect to an external power source, but nothing else is happening. In the AT commands it is coming up with AT+CPIN? which I can see means an error with the SIM card. (Just wondering if this is something to do with APN settings?)

    Another query I am wondering about..I have purchased a GiffGaff SIM card that says it is 2G/3G/4G compatible. Should this be okay for the device? Also I am in the UK.

    Any advice would be great for a newbie.

    Lucy

    Have you tried asking on the Arduino forum at https://forum.arduino.cc/?
    All advice is offered in good faith only. All my code is tested (unless stated explicitly otherwise) with the latest version of Microsoft Visual Studio (using the supported features of the latest standard) and is offered as examples only - not as production quality. I cannot offer advice regarding any other c/c++ compiler/IDE or incompatibilities with VS.
