Hi blatons, you mentioned yurself as a "download Freak".So, I think you concern for the total reusable data of the total data transfered under your connection.Instead of going for UL1350 plan ( where you need to run your system 24/7) to download 5 GBi suggest you to go for H500 , here you get 2Mbps(=250KBps) and the unlimited duratin 0200-0800 = 6 hrs => if you schedule properly, you can download 5.4 GB (if you get full 250 kBps speed, *it is possible* )you can atleast get 200 KBps means you can download atleast 4.32GB perday. What you save is [850 + electricity charges+taxes on both]If you also browse extensively, then you can go for H1000 plan, where you can have day usage limit of 5 GB(per month) , which is verymuch sufficient..But the advantage with an unlimited plan is that , we can start downloads whenever you want.. , But if we compare costs,data b/n these plans ,what i feel is night unlimited plans leads the way.
