Well what can I say about Airtel? By far the best service as on date - atleast in the southern region (because I dont know much about the other areas). I started off with a magic card with Airtel & at that time I wasnt very much into cellphones. But the mobility it gave me thrilled me. My associates could find me anytime, my family could get in touch with me anytime & I was so much within reach. Especially with my line of work where I have to stay @ the work site for hours @ a stretch & dont have access to a telephone because I a not able to reach the phone which is pretty far from my workplace (at the site office) I found my cellphone very handy. Then I thought about longevity of the service & my continued use of a cellphone & decided to go in for a Post Paid Connection. I was very pleased at the kind of prompt service. I got the card as promised, activation was a charm & service was great. I would recommend Airtel to people at the moment. Although Reliance & other services have much to promise but yet to prove a lot more Airtel has already proven itself & established a stronghold here. So id play it safe & go for Airtel.
The congestion @ times is a killer though. But hey its something we will have bear with. You cant have everything going your way all the time!!
