I chose mainly for the reason for this device because they allow companies can use 2 SIM cards simultaneously. Similarly, the presence of two cameras also of importance. The unit is very clearly structured, operation without reading the instructions understandable to everyone. Sometimes you have to search for the sub-functions a little, but that also has the advantage that you can place the device gets to know really. It is very comfortable to hold, the display is a good size. All in all I am very satisfied and would recommend this device to anyone!
