I have used uninor network for more than six month but now I broke the sim and throw away because it was not working properly.
Its network frequency is very low.
Its internet service is worst than any other mobile operator .
It gives many exciting offer of data service but it does not work properly as its speed is 1-2kb/second which is very worst than others service providers.
Many times it does not connect a call with other network as it does not operate in many state.
Its operation is limited to very less state.
So whoever wants to try this network please see my review.
