The phone is brilliant, actually. BUT, if you are going to buy a refurbished, unlocked phone, do not buy a formerly Verizon phone to use on AT&T. There were alot of headaches to get this to work, and I cannot use the standard voicemail setup because of this. I guess for the price, it might be worth it to deal with all of this, but I would suggest doing the research to know which unlocked phones are more compatible with what service providers.
These are not cheap phones but you get what you pay for. I came from an Xperia Z3V with Verizon. When it was time to upgrade, I looked and studied with the results being I liked Xperia Xzs enough that I took the leap to an unlocked phone and AT&T. It was a little scary, but there was no interruption in service. The specs and features on the phone are phenomenal. Xperia is the biggest seller in Europe where phones are unlocked. Here in US phones are tied to service. That's why Xperia may not have the most users in US but I can assure you, they are the most loyal.
