I absolutely wanted a dual SIM, n not being a big user of the internet, I can give my opinion, apart from the wifi to contact my box ca c is of simplicity) ... we hear very well ( voice and ringing tone) and use is very fluid .... no worries with Dual SIM (Italian chip TIM italia and an orange chip) rocker is easy ..... if you have to give a fault I would say to awaken, we must briefly press the power button and move his finger across the screen, there may be a simpler t it, but I have not found .. without internet traffic, the battery takes 7 to 10 days
