With so much hype around the Per Second billing, even I was about to get carried away. Then just my concious said, let me analyse my usage pattern and my current bill plan.I have an airtel postpaid connection with 995 as Advance rent for 2 years.Call charges are Local (any) - 50p/min STD(Any) - Re 1/Min.My usage is 100%local apart from 1-5 SMS/month.Upon analysis of my past 3 months bill I found out that after changing to the Freedon 249 Plan, I would be in a loss rather profit.Reason: - 1.Long calls mean a saving a 10p/min.2.Free seconds are only 10500 (effective 175 minutes)This plan translates that for the first 175 minutes, the call rate is roughly 2.37p/sec. (if taxes are excluded).So my suggestion would be that rather that going with the wave, analyse and only then move on.Finally, How often do we make a just 10-15 sec call or how often a call drops at 1minutes 2sec? Just check your bills once.
