This phone is launched by Nokia with his New own operating system Asha. This looks really nice and very easy to use because this phone's size is very small and light weighted. I am using this phone since 14 months and my experience is great. This phone launched with great features such are WiFi, Bluetooth, GPRS and USB. Nokia optimized this phone very nicely with his own Operating System Asha therefore phone doesn't lags. Phone also support instant messaging service like WhatsApp, Facebook messenger, weChat and etc. Overall my Experience is really good and I strongly recommend this phone.
