Vodafone India offers reduced call rate

"Hello! Recharge with 96 and enjoy all Local & National Calls and SMS

at 50p flat for 365 days. For details call Vodafone Customer care at

55555."

I think this is a better offer than the paisa billing offer of 1p per second.

Dial 123 (TollFree) to find out all about Value Added Services. Get
info on Callertunes, SMS BonusCards, Alerts and lots more. You can
also subscribe to any Value added services from there.

Vodafone India offers Second billing

Recharge for Rs.64 Today. Enjoy Unlimited Vodafone Calls (Local & STD)

@ 1 Paise / Sec + ALL Other Calls (Local & STD) @ 1.2 Paise / Sec for

1 Year.Call 121.

That would be the first Vodafone swipe against DoCoMo. But i like
Vodafone's 50p per minute offer far better than this.. It's much more
profitable for longer calls of 5 mins or longer.
