While surfing Tata DoCoMo Website got a link to their Wired Broadband services. Check the page here. It looks like now they are also providing BB services.
and Reliance also.....Right now I use their BB and Plan I have is freedom 999 plan (need to pay 1142 every month including tax)....12Mbps (1024x12/8 =1.5Mbps.........Every company does same they dont say original speed you get) till 25GB and than 1Mbps
1) Plans are costly!
2) One should always try to avoid FUP, as the speed becomes way too slow after the main usage.
3) The 512 Kbps plan price is almost double of mine! :O , and again, if its wireless, then it can have high latency problems too.
