Low cost 3G Mobiles

I was looking for a low cost dual sim 3G mobile as my 1 year old Samsung Star Duos was slow on 2G / WiFi. I found Samsung 3G dual sim mobiles are costly. Then I came across Karbonn & Micromax. Exchanged my old one & brought a Micromax Bolt A59. Its very fast

Karbonn Smart A10 is another dual sim 3G mobile with 5 mp camera and low cost

Karbonn Smart A11 Star is another dual sim 3G mobile u can consider Rs. 4,499 INR on 12/09/2014 @ flipkart
