My ThinkPad T14s shipped with an Intel XMM7560 LTE modem locked behind a Lenovo unlock blob. I replaced it with a ~100-line bash script that does the exact same handshake - and explains, in plain shell, what the "unlock" really is: a SHA-256 over a 4-byte constant. No magic, no blob.
Full credit to Floris Stoica-Marcu for the script.

Looking forward to work with #modemmanager upstream on improving dual SIM support in our #LinuxMobile stack: https://nlnet.nl/project/Linux-MultiSIM/ .
Thanks a lot to @NGIZero for supporting this!
This is how you cable a macro site, right? Hey at least LTE lights up. Still working on the gNB side.
We've released a new version of mobile-broadband-provider info. Besides updated provider info and more #cellbroadcast channel information we also added emergency number information:

Well I bought the AirVelocity 1901 that’s been on eBay for months, so assuming it actually works and I can guess the console root password (hopefully one of the ~10 known default ones), maybe I’ll have an n48 gNB for #ModemManager testing…
Not gonna hold my breath though.

… so far so good. The mechanical part seemed to have gone well and #ModemManager recognizes a #5G connection. No tests, yet.
I keep posting these until it gets boring: #Cellbroadcast received yesterday on a #OnePlus6t running #Phosh , #cellbroadcastd and #ModemManager . Just showed up, no fiddling, just using distro packages.
Although the project finished some months ago: Thanks to @NGIZero for funding work on this.
Let’s build a GPS-backed NTP server to sync a bunch of LTE base stations, instead of each one having its own GPS antenna
