Summary: For the price you pay for it it's definitely worth it Duo sims really helps to save carrying additional phones when itself does the job for answering private line and office line. But the second version should be better.
Summary: Excellent/superb WiFi reception, very nice and clear screen, works perfectly both sim cards. It take decent photo, and focus not so great, but for a fraction of money, its a excellent smart phone. Sony does a great job on its smart-phones. On and off, I got 5 different models.
Summary: I got this phone for the purposes of not having to carry two phones (work and personal) or for traveling. The phone aesthetics look nice, but it's plastic and so feels a little flimsy. The phone itself is good, both sims work fine although I don't use the phone much (reason later). It runs Android but is a little slow compared to other phones, or maybe I'm just used to my iPhone 5 speed for apps and turning the phone on.
