I am using this network from long time and I think it has one of the widest network range . And more importantly it has no network problems which is one of the main cause of other network operators. It has some good net plans and other plans but I think some of them are costlier than other network operators . But sometimes it also gives free net data or provides full balance offer which is quite helpful.
And at last it has a good customer service which is the key factor for any of the operators.
