bsnl evdo kerala speed review

Finally I thought of writing again about the BSNL EVDO again. I am using the EVDO for more than 2 months now . I uses the device from cochin( Kochi or Ernakulam ) or from calicut. I have taken some sceen shots to show you the speed of EVDO. I used to be online every time. So I knows the speed of EVDO of each time. 


I am having 2 shifts in my office. ie I have night shifts and day shifts in my office. So after my night shift I reached home around 3:00 AM. I used to browse from 3:00 AM , dont know how much time I will spend , it depends with my mind . You all can guess how many users will be there online in the night ... You can see I have full range for the device . Though it has full range the maximum speed I got is 200 kbps . But not a static one, upto 0( Zero) kbps .
The BSNL is telling you will be getting a speed upto 2 Mbps. I have not seen a speed more than 512 kbps itself in this device from Kochi. What the hell they are bosting , I dont no .
When I reaches calicut , I have two internet connections , one this EVDO and the other my bsnl broad band land line connection. I have a home combo plan of 500 C there.  The 500 C home combo plan of bsnl is a good one. I started the dataone with the starter plan of 250 per month . But it has only a upload / download of 1 GB. But the 500 C home combo plan of BSNL has a 1.5 GB transfer in day time and an unlimited night surfing from 2:00 AM to 8:00 AM. I used to browse with EVDO in the day time. The tower will be 1 or 2 . Not the 4 range will be shown . But still I got speeds upto 384 kbps and all , some what static. I may need to rethink about the EVDO whether I need to continue it or not. 
The tariff plan of EVDO is 550+tax per month . I bought EVDO to use at Ernakulam . But when the speed of evdo in ernakulam is like this, then whats the use of it ? Often I got the page "The page cannot be displayed". 
I remember my father's wordings. "Why do you want to buy this so urgently . Wait we can buy after some time ". As I am a web developer I can't live with out internet. Its some what killing me when there is no net . So I don't bother his words . 
At the time , there was none offering an unlimited access like bsnl evdo scheme , so I bought it. In the previous post I have described my pain for buying the EVDO. But now I have seen an advertisement of Tata Indicom offering unlimited internet in the same pay . I think it will be good switching to Tata rather than EVDO for now. Tata offers roaming to other states , but EVDO doesnt offers roaming to other states for now. I will loose my 4200 for the device. Anyway it will be better to look for some more time to see whether it will works good or not ?
