well, really a great move by Mtnl..airtel will surely have a tuff time in retaining their customers.well, really attractive plans are 512UL combo and 256 UL combo..512 UL combo comes with 500 free calls for 1299 Rs.If u assume that 1 call costs@ 1 rupee then the effective BB charges for 512UL is a mere 800 Bucks.while 256 Combo effective charges for BB is 500 bucks only.They have also chopped installation and security charges.owing a unlimited BB is as simple as paying 600Rs(installation+security charges)+ the montly rental of 599 Bucks and 100 free calls.This is amazing stuff from MTNL...HATS OFF to MTNL:dance::dance::dance:
