You get all of simplelogin with unlimited. There is a way to convert your login so you won't lose your setup. And I BELIEVE that it prorated any unused time you had left on your simplelogin account, so you would get credit for the 3 months you have left when you convert it... But not 100% positive on that, check with support. But I do know when I converted mine a few days before simplelogin was going to expire I was charged for a new month of service with some credit applied. So there is a process.
IMO if you're using proton mail, and simple logon anyway and want a VPN then unlimited is kind of a no brainer. It works pretty great for me.
The amount of work he is putting into this is really impressive. Being from the US it kind of sucks to see his play out in every country but ours. Is 'merica just a lost cause or is there something else we can do here?
