Hi my name is rajeev. and I am going to tell u about aircel . I am using sim sience 4 month.very bad network and not costmar spport. One of the worst mobile operator I have ever seen. Recently I bought aircel sim. I m facing a problem in network in my areaAircel closed compliant without share permission to me, no network 24 hours and no gprs or internet work 24 hours. I lost many money for internet but poor quality and poor network for 2g internet. It is a matter of shame for the company.
