Aircel provide all type of service chief and best in comparison to other network service providers. So I want to use it . But when I use its service in the roaming it is not working properly, during this reason I have to face so many problems with this poor network . I couldn't do any call, net serfing and not receive any call . For this reasons I dislike it. I have no any billing disputes. When I remove this service and join with other strong network and service providers then we have to no any problems with this. While using in home towns and roaming no any difference to use. Now , for this service we to pay a little bit more than to previous service.
