You can buy this operator because of these reason it have a very low call rates, browsing charges and offers . but the service and network is worst assume you are going any where and you do not have a network in the mobile.
And it is urgent to call someone so the thing is main problem of this operator is network and the frequency and the call drop is also a problem with this network, call can be drop any time while you are talking and you have to call back again. so if you like to buy this operator just check this review .
I am using this operator but as a optional because the network problem . and sometimes the operator cut your balance for the fake reasons they will auto activate any service and deduct the balance and even if u will ask about them they tell you the strange reasons and its difficult to get the balance back .and the customer care also not good you have to call and wait for hour to connect the call so if you are looking for a good network and service you should avoid this operator but if you are looking for low call rates and low browsing charges then you can go for this operator.
