I have used this sim card around 1&half years, I had never thought I will face such a worst experience, network coverage is very poor, in my room of the hostel range is totally zero. Even call rate charges are very high compared to other networks, being an old customer they do not provide any concession, sms charges on the peak, in these days where most of the companies cutting the cost their charges even are not in the range of our needs, that’s why I finally switched to another operator.
