Hi guys ...i have booked tata broadband connection which i will get within a week for 256kbps night unlimited for 199 rs pm but i also heard abt 9pm to 9am 2mbps unlimited for which we need to buy thr prepaid and im interested in going for tht option but i want to make sure tht thr is no hidden cost in it and also i want to kno whether 299 will be charged to me seperately or will be deducted from my prepaid balance .
