This is one very interesting phone. Its responsiveness and speed is more than what we had expected.
The Dual Sim function removes our need of carrying two phones when we need to maintain two lines or are travellers. Only other reason to carry two phones instead of this phone is due to the need to preserve battery and have a back up device should this fail mind set.
Other wise when one line is not needed it can be easily turned off with the soft switch that is contained within the settings or using the short cut pull down menu.
Below is a capture of the specifications that are available on the manufactures website, along with the link it came from. Do not in time the link may not work as newer models come out. But here it is for now.
