I was used this operator about 5 years. I dont seen this kind of sim card in our life . They show many offers but still this is dumbed. very bad network, service very weak.Many time he cut my balance without any service and when I complain them he asked me to solve shortly and after that he did not pick the call and tells that he is busy.Bad customer care service and very bad network coverage.I complained many time about network related but he tell me last 3 year that I will solve your problem within 72 hours
