Trick to surf free on BSNL Dataone Night Unlimited Plan

I use BSNL dataone connection 500c plan, I was often wondering if there were any tricks that apply on the BSnl. One day I forgot to disconnect my BSNL connection after 8 am,which is the limit of free download time (2am-8am).

When in the evening I looked my usage detail I was surprised to know that I was not charged for using after 8am… so I started to use the trick, it can atleast extend your free download time upto 1/2 hour (I did not experiment beyond it).

If you want to extend the free download time. Here we go….

Just connect before one or two minutes before 8 am, and use till it get disconnected automatically or the link disappears. You will not be charged for it.

Here I am putting up a screenshot of my use.



Its just a trick and you should strictly avoid using such tricks as you may sometime end up getting a huge broadband usage bill.

  1. I’ve contacted BSNL officials and didn’t get any positive info for a week. The reset is at random intervals.(this is why bsnl s*ks) 30 min can account to 200MB or more.Just don’t try this if you wanna save your pocket…
    @ Prashant Vishwakarma. Resize image before posting..

  2. As per my knowledge and usage, I think the Bsnl server responds 20 to 30 minutes later from the given time (2:00 am – 8:00 am)… that’s why the free hour starts at around 2:20 A.M and stops at around 8:25 A.M.

  3. @srinivas the link you has given states that the user is charged according to the time at which he connected the dataone,if u connect in time(2-8) u ll not be charged.m dead sure,they provide this flexibility,but net get disconnect after 30 min max.

  4. It can happen..Similarly like Sify and Airtel…but its all about taking chNCES…You might be lucky for a time or two…but once you will get charged..Probably end of your bandwidth…

  5. no need to conect before 2 minutes just ccontinue ur dwnload it works for abt 5 to 10 min not more to me


    In short. BSNL s*cks. They are not able to manage an automated reset @ 2am and 8am . Thos who get to use extra time may be happy. wat abt those who get billed for using after 2am???
    I got official communication on this issue will update the post soon.

    Again my site(crimechamber) is down. Can anybody share your server space with me for 6 months(until my final yr is over). I get only 1000 page views per month less than 500MB bandwidth.

    BSNL have updated their rest timings which makes this trick obsolete. I request mods to have a clear warning left at beginning of the post for the welfare of DW visitors..

  9. Namaskaar bhai logon.

    I wud like to explain how this trick works .
    BSNL server maintains the chargeable units by making session of 30 mins. They cant break ur downloading session at correct 2 or 8 am , instead they break it after 30 min of ur start or login time( the time at which u plug in ur modem). So if u started at 01:55 am , then this session will automatically break at 2:25 am and all the downloading done in this interval ( upto 2 : 25 am) will be charged as the session started before 2 am.
    Either u start ur downloading after 2:30 for being safe or follow this trick if u want ur d/nloading not to be charged after 2 am :

    Plug in ur modem (on ur sleeping time) at either 11:02 ,11:32 , 12:02 , 12:32, 01:02 , 01:32 or 2:02 am . Then dont touch ( ie dont ON & OFF ur modem) till next morning .

    Staring ur session at ni of d specified timing will break ur session at 02:02 am . And then all the downloading done will be free as the session startd or broken after 02 am.

    For proof u can see that their session period is either of an half hour or 1 hour or 1hr 30 min etc ie a multiple of 30 min

    So the leader of this post is right if u plug in ur modem at 07:59 am , u will not be charged upto 8:29 am .

    ATTENTION : these all timing sud be synchronised with BSNL server clock ( as displayed in BSNL potal website).

  10. ya,its right,i had also seen several time that when i forget to disconnect upto 20min…the use is not charged

  11. The trick was workinh perfectly before…but now-a-days…if u r connecteed from just before 2minutes from 8 and get connected nearly 1/2 hours…they pay separately after 8a.m…so dont try this trick now…

  12. Thnx
    I know that its a silly question ~ but if i connect to net at 6:00 AM and continue till 8:25 AM ~ Will I be charged
    If this trick isnt working properly,then why dont U del the post
