I am setting this up per those instructions:

using USB3 as Device doesn’t work if I have to use USB2 for the port when executing AT commands? So should I use USB2 as the device and execute the commands against USB3? What do I do when I am done executing commands? Should I reboot the Amarok or reset the modem? Something else?

Currently, it does not say Sim card not registered. But it is not serving internet either.
