Forum for advanced users who grok the power of text-based apps, the advantage of tmux/GNU screen, the keyboard and who often find the mouse a hinderance to a fast workflow. A text-based UI is also a decent escape from enshitified resources.
This forum broadly covers tools, hacks, and advocacy of text-based environments.
Slightly marginally kind of related:
I actually have no idea, what I'm talking about, but is RCS even possibly without a SIM Card?
I guess, it's just doing stuff over internet anyway, but is it hard linked to the SIM card, or how does it even work?
Not sure how much reach RCS has, but here in Austria, I haven't seen one using it - I'm still fighting to get people off WhatsApp and onto signal, not sure how much leverage I have for stuff like RCS
I’m not real familiar with RCS either but I got the impression RCS could be used to send an SMS to someone without having mobile phone service yourself. The old way was email gateways where you email $phonenumber@sms.$carrier.net and the msg is sent as an SMS (at no cost) to the recipient at that carrier. But those email-sms gateways are dying off and you need to know which carrier the recipient has.
BTW, I suggest avoiding Signal:
