Hi friends I have been using airtel since last 4 yrs it is the best network I have used I also switched on to bsnl and idea but again I came back to airtel.the network strengh are strong and they reach even into the remotest areas .only bad part about airtel is that the data packs are too costly. I neer felt the use of talk time and message packs.but if airtel could offer some best offers it could become perfect service provider of country .so you people can use airtel its good but for data packs you should switch on to bsnl.
