Simplest 3G/4G connection for Pi, must work headless and stand-alone

Are there any simple 3G/4G add-ons for a Pi that will allow it to power up into a mode where it has the ability to be connected to via the mobile data connection? I want a system that I can connect to from my home desktop/laptop on demand. Sort of 'thinking out loud' about this:- I suppose a USB 3G/4G dongle could provide the hardware required to make a mobile connection to the PI, recommendations? It has to 'connect on demand' dialling *to* the Pi, it can't keep the line open all the time, very expensive! So, is there software for Linux (and thus for the Pi) which will handle incoming calls to allow ssh login? How does one manage the other end? Is there Linux desktop software to allow one to dial up a remote system and then squirt ssh down the connection? Any/all ideas would be very welcome. I'm happy with fairly low-level stuff, I am a retired software engineer, grew up with Unix (solaris) command line and I'm also quite into home-build electronics projects. -- Chris Green

Not for me then. Our university offers a VPN for all students but I have no access to any of its actual computers.
