Karbonn K4

Hey frnd's d phone is gud. Sound wireless fm al perfect. It has a superb battery back up n safety ie privacy protection. N d drawback is tat u cant keep al d photo of ur choice as wallpaper n d back panel/cover is very tight, one gets a feelin tat v r breakin it. D headset is nt 3.5mm jack. Overall d phone has classy look can give 4/5 ratings to this mobile.

Don't you think with intellect

Although bulky & costly the battery is very powerful & useful for a businessman like me.Even on heavy use on both the connections with incoming & outgoing calls it gave me a talk time of 8-9 hrs and standby of 4-6 day that too WHILE IN TRAVELING.
Don't you think that this is a Best option for 500-600 Rs we R going to spend for a 1000-1200 mAH battery of SO CALLED BRANDED Company.

Dear friends search,study,think and decide with the help of powerful tool like Internet
