Don't rely on RCS! Unfortunately, #RCS is worse than #SMS. (It used to be worse than #CVS, but that was something completely different.) #FreeSoftware operating systems can easily support SMS and even #MMS, e.g. with #ModemManager. RCS is completely locked into #BigTech #duopoly Google + Apple and cannot be supported by #Mobian or free Android flavours. Use #RFC6120 instead. Open, free, #standardised, federated #InstantMessaging for all! #federation #digitalSovereignty #IETF #Jabber #XMPP

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. https://blog.hofstede.it/replacing-lenovos-wwan-unlock-blob-with-a-100-line-bash-script/ #Linux #Fedora #ThinkPad #ModemManager #FOSS
