Hi friends I had ported my postpaid number from Vodafone to Airtel that time I was thinking that airtel much better than Vodafone but when I use airtel service I was very disappointed with their network belive me guys some time whole network gone from my cell there is only one network bar left in my cell therfore I lodged a complaint in airtel regarding network issue and they assured me for resolving this issue I waited for 4-5 days but my problem still not resolved by them.
Finally I need to say that airtel network now become Aircel type network
