The network coverage of Reliance Karnataka is really not good.
The network towers are very few and does not provide proper network coverage as compared with other service providers.
The cost of calls and the internet cost is quiet low. But what is the use if there is no proper network coverage to make a call or use internet. The speed of net is also average.
Due to these reasons it is not preferred by people in Karnataka. hence I would suggest Reliance networks to focus on network coverage.
