When I plug in the em7305 network card and sim card in my X230 machine The computer can go online normally

After the lsusb command is entered, three usb devices are displayed  （ttyUSB0  ttyUSB1 and ttyUSB2）

What command do I need to enter, then I can get the link em7305 and I can enter AT commands
