I can also recommend OSDE. I'm happy with it. I particularly like being able to get a house call from the OSDE doctors. Though I think that is on hold during the pandemic. Otherwise every doctor I have wanted to visit accepts it (I have the 310 plan). My wife has it as well and has a doctor she likes at hospital italiano (she paid out of pocket when we first arrived for her first appointment there) and OSDE covers her appointments there. So as people say flexibility is nice.
I never tried house visits with my OSDE 310. Sounds like an interesting option. Do the experts also come home?
Recently during Pandemic , I required a doctor's certificate that "I have no fever or flu like symptoms" and requested for a house doctor. Proved to be impossible. OSDE has a made a app where it seems doctors provide you advice online but I found, the app does not work those OSDE did not believe me. However, I was able to find a OSDE doctor v v close to my house who met me personally and issued me the document. It was v v helpful to me.
