I am working on Dell Edge Gateway 5000 series and have installed Ubuntu Core 16. I am trying to make it as Access Point. I have inserted a sim card in it and have created a connection with the command below.
nmcli con add type gsm ifname ttyACM3 con-name apn user password
When I run the command nmcli con, I am able to see that connection registered. But when I try to up that connection, I am getting the following error.
Error: Connection activation failed: No suitable device found for this connection.
Please let me know what steps to follow to connect to the sim card network.
