From last three months I am using there free sim because they offered it for totally free for new users as a part of there advertising strategy and company policy.
About this sim, Network and everything is good and I am happy . I will not say that is bad but the customer service is not so good for now.It is new will improve by time but for now a days I did not like the way when person talked with me on the phone.
My area do not get good network but they are still able to provide good network so good on that part.
But need to see how long they will provide the service at same price that they are for now.
