A few brief observations:
1) I do not like the fact that you cannot have GV and Fi. They make you choose one or the other.
2) I was aware of the lousy service here in Lakewood for T-Mobile and Sprint, but I was counting on Fi's advertised usage of public hotspots. I assumed they had contracts with the major providers (Comcast, etc), but I have yet to been connected to even one public WiFi. If this continues, IMO in Lakewood the service is barely useable.
3) Support is adequate. I had a question during activation. The two options were email and a call back. I selected call back, and received a call within an hour. The person who I spoke with was American, friendly, and moderately knowledgeable. After I activated, I had another question. This one was not so urgent, so I selected email. But I did see there was a chat option as well.
