I am using airtel since 4 years and its the best network than any other it gives a gud plans.recently I converted my prepaid service to post paid service. as per my job I have to travel many areas near my locality.
And has to give feed back.airyel rocks its signal every where and make my work easier.lot of my co-workers also converted to airtel and using a CUG connections through it.my suggetion is to switch to airtel and if possible take a postpaid and enjoy its services.
