As cheap like price, the network coverage is also comes cheap and breaking sometimes. The rural areas are always runs with low or nil network coverage. Hassy voice and blank calls is a common issue on this network. Sometime I hear my own voice back to my phone. Data speed is compromising slow as it comes free with offers.
So only use this as secondary option to use.
