Samsung Galaxy C7 Pro is a very smart & nice phone. it is very easy to serve for anyone. its quality is very high and it can use anyone.it is launched recently, most probably January 2017. so it is a very latest mobile for us.it is different between other that it is dual sim phone but not only input GSM. but also it can be GSM+GSM or GSM+CDMA. so it different to other.its battery is most powerful its powered by 3300mah non removal battery. Samsung galaxy is a smart phone that accepts nano sim.I suggest to all buy it.
