Summary: I took this phone to Hong Kong and it works great. I was able to get reasonably fast data and the call quality was fine. The battery life seems to be depleted faster if wifi is used rather than broadband. I also used it to take photos and the 5 MP camera is just fine if you are aware that you're not going to be getting iphone-level quality photos (but they're totally adequate for snapshots).
Summary: The Dual sim feature works really well , the camera is surprisingly good my previous phone had 12mp camera, battery life is good for 3 days, Android software is easy to use my previous phones were Nokia's I was able to transfer all my contacts across ,basically a very good Budget Dual sim phone-smart.
