It is not just Karbonn Mobiles, even Spice Mobiles are gearing up to launch a new handset on 15th September at 3:30PM. Interestingly the timings are the same, however Karbonn will sell it via Snapdeal and Spice will do it via Flipkart.
So what is it? Well most likely the Android one, and more clues pointing to it. Google will be launching the Android One on 15th a few hours before Karbonn and Spice Mobiles makes it official on their respective eCommerce partners.
As you can see they have kept the timings same, so both the new handset (the Android One) from respective brands will go for sale on different eCommerce site simultaneous. Most likely the design could be the same or with minor changes. It would be interesting to see what these companies price it at.
The Android One are low cost smartphones created by Google with a price tag of $100. It could be price around the same in India or a little more. So watch out for dual dhamaka on Monday the 15th September 2014.
