Kali 4G Modem AutoStart service

I’m trying to make Kali start the 4g modem on startup.
so far I went to /etc/systemd/system and created a file called cellmodem.service
Next I entered these things:
[Unit]
Description=Start Cellular Modem
[Service]
ExecStart=/usr/local/bin/uconsole-4g-cm4 enable
ExecStart=/usr/bin/Sleep 60;/usr/bin/systemctl restart ModemManager
[Install]
WantedBy=default.target
------so after all that I saved the file from nano and entered:
systemctl enable cellmodem.service
but it doesn’t work, am I doing this wrong? Help Please.

I may be wrong. I haven’t built a script in ages. I believe after you make it you have to use the command line to make it executable. I hope this at least gives you something to Google.

Ummm… Did you try systemctl start cellmodem.service? enable causes the modem to run on startup, assuming your service is set up properly.
