I am trying the EM7565 development kit on windows 10. I have ATT SIMS activated through Sierra. I am getting an error when I try to connect, “Can’t connect to this network” “Cellular data isn’t working properly. Try again later.” ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/d/da54f8a8eb864f7f1d00d445a50c6e3c205fade9.png) I am powering my device off of a powered USB switch and I have both of the provided antennas connected along with the short cables to connect the radio ports to the devkit board’s ports. Anyone have any ideas? I have installed the firmware noted for ATT at [https://source.sierrawireless.com/resources/airprime/minicard/75xx/airprime-em\_mc75xx-approved-fw-packages/#sthash.YQLOVVFZ.dpbs](https://source.sierrawireless.com/resources/airprime/minicard/75xx/airprime-em_mc75xx-approved-fw-packages/#sthash.YQLOVVFZ.dpbs) . ---

Do you have modem port in device manager? ---

It turned out I needed an APN. Now that I have that, I can connect but I can’t get a DNS server. I also can’t ping the gateway. To send AT commands, I assume I connect to the DM Port above (happens to be COM12 on my system). Is it 9600 8n1 with no hardware flow control? I tried that with PuTTY with no luck. ---

Not dm port, it should be modem port for AT commad ---

Thank you for your help so far. The SIM question is a good question. I can send but I can’t receive anything. I can get the app to track sessions but it also shows no data received. Do you know SIM diagnostic commands that I can run? ---

Hi @jyijyi I’m trying to establish data connection with my EM7565 on window 10 but having similar issue as well. I don’t have the GSM antenna installed yet but the AT!SCACT =1,1 return error.

have you set the correct APN in +CGDCONT?
