According to this Update,The Tariff will be for SMS:

2. Every SMS beyond one hundred SMS per SIM per day Not Less Than 50 paisa/SMS But Telecom Comapanies(TATA,AIRTEL,IDEA) Usually Charge Re.1/SMS for Local SMS and Rs.1.5/SMS for National SMS
So From 20th November 2012, You can send 100 SMS Free if you have activate any SMS usage pack, when your 100 SMS limit exceeded then your Service provider charge you Re.1/SMS for Local SMS and Rs.1.5/SMS for National SMS. 
PS: It can be 50 Paisa/SMS for your Service provider As TRAI’s SMS Tariff is “Not Less Than 50 Paisa/SMS After 100 SMS a Day”. So  Do confirm before Smsing over 100’s SMS.
The Telecom company send SMS’s to their customer for this change , As I use TATA DOCOMO I have received the Same Message:
“As per TRAI rules from 20-Nov-12, SMS pack & free user can get 100 discounted & free SMS/day, Thereafter SMS will be charged as Local@Re1 and National@Rs.1.5”
