Summary: I would have given it a 5 star, but i am giving it a 3. First because the settings to use data from whoever you choose as your cell phone carrier is complicated. I almost returned it thing the phone was faulty until i was worked through it. Secondly, the battery has little or no life. My former cheaper Blu phone had more life to it.
Summary: i heard that the F versions do not work with Lte in the USA. Not sure why sellers are not specifying for this is very important information. the only reason most of us want to buy such expensive phone is to be able to enjoy all the features that comes with it...especially Lte network, which means faster speed.
