First of all… yup I fricked it up, the filename is wrong. it should be uConsoleLTE.service. by the way there should be no * symbol in the command, remove them. (Why you add those things in?)
Second, have you ran sudo systemctl daemon-reload before running those commands?
Last: You may want to look here for more information: https://forum.clockworkpi.com/t/uconsole-lte-modem-how-to-guide-for-a06-with-9001-stock-firmware
The GitHub Gist is updated to fix those filename issues.
