I have a USB stick 4G modem and I automated the connection setup; it has a web app (starts a small embedded webserver when you plug it in) which I "reverse engineered" and I wrote a small script which makes HTTP requests so I don't need to go to the web interface, login, enter PIN code and click connect every single day multiple times. I just run "telekom connect" and that's it. What a time saver! :D
