I have been attempting to setup my Tachyon and have been unable to get it to setup and establish a cellular profile.

Here is the output from:

`journalctl -u particle-tachyon-rild --no-pager`

I'm in the UK (and selected that region at setup). I have attempted install 4 times and ensured I was outside during the 4th setup (to make sure there would be a good mobile signal). I've tried the troubleshooting steps suggested in [Cellular Modem | Particle Developer](https://developer.particle.io/tachyon/device-details/cellular).

Hey Luke! I'll loop back on what is going on here - could you share your particle account email address? You can DM [@support](https://community.particle.io/groups/support) if you want to keep that hidden; just click on the link and select Message.

Thanks
