When I asked at the local electronics store as I was getting my phone service re-established, I asked about home Wi-Fi with TIM, and they said it would be 4-year contract at 30 eur/month. I was in a jet-lagged state and didn't want to think further at that time. With the service I had before, they said it had to be paid 6 months at a time, and the price I last paid would amount to 200 eur/year, but I worry about finding it not working on arrival and waiting for a service call.
