Kechaoda was a china company some of the china mobiles were blasting so take care of china mobiles kechaoda k66 was 2.5 inch and camera was very less not able to capture photos and it sound was very loud it makes nuisance for other people and the battery life was not good we cant use them for official the rate was cheap to buy we cant use them for our official life so I strongly recommend not use.
China mobiles and use our Indian mobiles.
