Hello friends As we come to the tablet world the cheapest one is datawind ubislate
but friends its a 2g tablet, configuration is ok but it does not support 3g or higher network, the company is taged with reliance, only for browsing its free for 1 year, but its 512 Ram, batter is somewhat okk but over all its not recommended for newer generation, as it is not compitable with 3g or higher so it is just a fun, for children, it works like a mini laptop, as it comprises the specification, but comming to network its not good
