They must be having some hidden terms and conditions for free. All these schemes are just to get the attention of consumers. Once you take the connection and when you get your first bill, you will come to know the actual scheme. lol
True
A call is calculated by pulse rate.. whether you are using 1 seconds or 600 second is irrelevant... A one second call s well as 600 seconds calls ended with the same rate Rs.1 in this case...
However there are some catch.. such as drop in the calls..
Say customer A is calling Customer B.. call A will redistered in call B cell but before B answered call A has been cut up from CAll B..
So 'A' think he didn't properly dialled so he again attempted the same call and same result finally he give up(after ten times).. So theoretically Customer A didn't made the single call...But in the CDR of the customer A 's mobile service provider will register this call as one seconds call and sent this detail to the billing server as ten different calls means Rs 10/- charged...
TRAI has aware of this drop out calls, and advise the MOBILE services providers excluded this from the billing...But MSPs are not doing this automatically.. only when the customers who got the detailed bills, point out the dropped calls details the nodal officer will discount the charges in the billing..
If TATA can give without dropout calls, the service is really good.. So be careful with your first bill..
