For #lenovo #thinkpad #t480 #t480s #t490 #t490s #t440 #t470 etc. #tseries under #nixOS does a/the #LTE #cellular #modem (e.g. #Fibocom #L830-EB #4G LTE #WWAN Modem) work without special measures i.e. does it "appear" in the GUI OS e.g. #gnome & become available for use automatically on installation or update of nixOS e.g. by running update of configuration in usual way? Are there special options in configuration.nix one has to set first? Even then, does it work? Anyone have LTE success here?

Moreover, it appears that TMo are using the #Fibocom FG360-NA-03 specifically as seen in aforementioned datasheet. The difference with the FG360-NA-00 and FG360-NA-05 versions is that their datasheet lists "driver" as “Linux 4.1” instead of OpenWRT for the -03 spec. Main difference between all of them seems to be supported wireless bands as they apply to the carrier. The -03 variety for TMo appears to support a bunch more bands (TMo + Sprint) as a result. The #MT6890 AP is a #CortexA55, for completeness sake.

What, you thought I wasn't going to self-nerdsnipe? So according to TMo's datasheet[1] the gateway contains a #Fibocom #FG360NA 5G module which itself is built on the #Mediatek #T750 SoC, which (yes it's turtles all the way down) contains a number other MT ICs including an #MT6890 quad-core ARM AP. That processor apparently is running a "driver" designated as “Kernel 4.19 #OpenWRT 19.07 (?)” but according to the previous research it boots Android? Weird stuff.
Wish me luck while I decide whether to attempt soldering headers onto the alleged UART connection of the 5G gateway I am supposed to return unharmed to its rightful owner, eventually 🧯
