the reason for this thread to be popular is very clear.
MTNL is the cheapest mobile 3G service provider in the country with un believable 3g rates.
When vodafone , artel charges Rupees 10 & Rs. 15 per MB respectively, MTNL is charging Rs. 0.83 per MB and their unlimited plans are still better.
Private operators have paid extreme high license fees and are unable to support their fees. so they are charging those Rs. 15/MB data charges on 3G.
MTNL on the contarary is reducing the 3G rates. So cheapest 3G will attract the maximum crowd !!
