Perhaps the most important points. To switch between the SIM card during phone calls back and forth is necessary no complicated restart. It is, however, proceed as follows: zurerst enter the phone number or select the phone book. Only then is possible to select the desired SIM card with the button on the right side of the device without rebooting. However, it is simply a joke, that this feature is described in the manual rather meager at any point. It is this possibility is likely to be a function of Haupargumente for purchasing a dual SIM phone. And as I have taken a few recessions, the mobile phone has just returned for this reason again. Hence only 4 stars for an otherwise Top mobile. Great design, excellent voice quality and good workmanship. But a bug I would have but to mention. When you copy data from the SIM to the phone or vice versa go with every copy transition data lost or double and triple adjusted loss of other data. Therefore, before backing up data to another device.
