I bought this phone because my Android phone come in the years and has become more and more slowly. Since I have professionally, a phone was bought this dual SIM phone. The decisive factor was also that I was curious about Windows Phone. Moving from Android to Windows has been easy. Unfortunately, there are not as many apps for Windows Phone as Android, however, are needed by me available. The unit is robust and impresses with its bright orange color. Calls run on both SIM cards clearly, the same goes for SMS and MMS. Internet, Whatsapp, Facebook, and any other apps running without jerking. Switching from Internet via 3G to Wi-Fi takes place automatically and smoothly in both directions. For me, a successful purchase of a well-balanced mobile phone at a good price.
