I have been usinh this aircel network for about 3-4 years and I must say it is a great network.but it has some flaws like you woukd find difficulty in finding network coverage, and calls drops too much.
But other than this this company usually bring too good offers like.you would find very cheap internet here and call rate also.but the service is not that good.and this company dsnt bring proper 3g service in india which is also a big problem
