I recall one time in 2015 or 2016 when I had only a very weak 2G signal, but wanted to check a couple of pages (at least one of which was several hundred kilobytes). Connections always timed out in browsers, but I got it working by SSHing into my VPS, downloading the page with curl, then copying that down with scp. My recollection is that the file size would increase by 32KB every 15–30 seconds. Fun times!
Mosh works over 2.7 KBPS capped data plans. I connected to a tilde and just use lynx/links/edbrowse for light www/irc/jabber and gopher. It runs much faster than being connected natively to the inet.
I can read everything and even answer in fora with Edbrowse.
