what size Sim and is this a dual phone?
What does Sim card does this phone use?
Is this a dual Sim phone?
How many hours does the battery last? Will it hold a charge for the
whole day if apps are not used much?
It supports Nano sim card. It is just one sim. There is one more slot for the memory card right next to the sim card slot.
Phone comes for a day. If it is 100% in the morning. By the end of the day I have 30 to 40% battery left with moderate screen brightness and usage.
Advantage of this phone is the entire phone gets charged from 0 to 100% in 75 to 80 min. So I really don't care much about the battery life.
