I bought Karbonn KC 750 last month for my grandfather, but apart from its low cost, this phone is good for nothing. The screen resolution is quite poor for this phone. Also the keypad does not work properly, one needs to press the buttons too hard to make the keys work. The phone has an ordinary design, and the sound, although loud enough, gets bad at high volumes. The GPRS doesn’t work at all. Once, the phone got dropped on the floor, and the key’9’ doesn’t work anymore. So not durable enough as well. Though low cost, I don’t think the phone is any value for money. So I don’t recommend this phone.
