Is it worth moving from Airtel prepaid to postpaid?

[webgenius]

Here is my sample recharge summary for my Airtel prepaid:

16th July: Rs 200 top-up
16th July: Rs 31 SMS pack activation
19th July: Rs 97 Call charge discount pack
26th July: Rs 200 top-up
26th July: Rs 103 3G pack activation

You see, I have spent almost 630 bucks in the last 15 days on recharges, and I have around Rs 250 left in the main account. I might recharge again when it goes below Rs 150.

On an average, I spend about Rs 500 to Rs 600 every month on Airtel (top-up recharge, SMS pack, 3G pack, discounted tariff recharge).

Will I save any money if I move from prepaid to postpaid?

With prepaid I'll have control over my expenses. Is it really possible with postpaid too? What if I use too much 3G and the amount goes in thousands? Is there any maximum limit to prevent such happenings?

Seeing your usage pattern, it's best to switch to Postpaid.
Moreover, Postpaid offers some attractive combos to pull the prepaid customers.

Are you working or studying?
Coz, there are special discounts for corporate customers..

I'm working. Will there be any maximum credit limit so that the charges does not exceed above certain limit?
