I using aircel post paid last one year actually it corporate plan it name smart 200. it is not bad people say but it is very less serviced. they should improve there there service, so that people can get more.before I was using aircel for a limited time.i was really angry because for any recharge I should suffer either I should make online recharge nor I should got to city .but other operators were very good in service.Plz see that if they improve more then it will become success for them .
