Nokia Asha 310 smartphone was launched in feburary, 2013 . it is 3inch with 240*400 display alongside 64MB RAM and 2megapixel rear camera. its OS is Nokia Asha platform. it don’t have good touch screen. you have to press hard to touch anything in this phone, specially while opening the locj you have to press the screen very hard. it has only 20mb internal space. but one good thing in it is that, it has SD card slot and it supports up to 32gb. it is a dual SIM phone. it doesn’t have 3g on any sim slot. its has FM and Bluetooth in it. screen sharpness is not good.
I will not recommend to you for this.
