I was a Fi user for about a year, but had major issues getting the phone to switch back to the cell network when I left my house. We live in a little valley with poor reception, so the phone seemed to "give up" on cell service, and then I'd have to reboot it after I left my house to get it to reconnect (wifi calling worked fine while I was home).
