This is the worst network company in India. This telecom company is owned and operated by central government of India so as a government company its network spead is very slow. The cost of data and calling is very high as compare to other companies that provide internet and calling facilities. The cost of 3G internet provided by this company is equal to cost of 4G provided by other companies. The customer services provided by this company is one of the worst service provided by any telecom company because most of the time their customer excutive number will not connect and if it connect the responce provided by them is not good. So I will recommend not to use this network because their internet is slow, their data pack are very high and their customer services are not good.
