Yes , it's true .
And , you just CAN'T call customer care and activate it .
All customers under 799UL 256 plan are applicable for this .
He/she can send "DELIGHT" to 53636 from their registered mobile numbers.
It takes 96
Working hours for activation.
96 Working hours = 12 Days. [ Calculated . True .

]
Under this Scheme , You pay Rs.799+100 = Rs.899 a month.
You get Rs.100 of talk value and double the speed ; i.e. 512kbps .
SO, you put in 100Rs , You get back the 100Rs as TT AND you get double the speed .
Not bad , Hm ?
And, yeah . This offer is referred as January 2010 Delight offer .
I'm repeating this ; Even if you haven't recieved any SMS/Mail from Airtel and you're using the 799UL 256 plan , you can send the SMS and get it for yourself .
Any further reasonable queries regarding the same would be answered by me.
I got full details.
