In few months I will start a PhD at ETH Zurich and I was wondering if it is possible in this case to change my insurance from Helsana to SwissCare. That would help me save quite a bit of money which is always welcome when you are gettign PhD money (which is still quite generous at ETH).
Would also be nice to know if I should just follow the normal student procedure and terminate the Helsana contract or how I could do it :P
