I was using this network for soo many years. In past 2-3 years I must say it was best operator from my point of view but now after converting into 4g it become worst and useless as it become soo much expensive. Now days I am not able to use this network. Its network coverage also become poor . Sometime my balance also deducted and when I contact customer serviece they blocked my no. And I cannot contact again, once my no. Was also being closed soo I bought another and since then it is useless
