Recently, I saw an advertisement which promoted the new 'SMS card' launched by Vodafone which promised free local SMS to all users (they don't need to be Vodafone customers) for 30 days for a price of 63 Rs. Are there similar packages for Airtel? I'm assuming that the so called 'SMS card' will have a code number on it which I will have to enter on my mobile card (just like you get those prepaid mobile cards). Please guide me as to the best plan for sending free SMS via airtel for a decent period of time. Please do not send links which show me all the packages for airtel but those that specifically showcase this particular package.
