BSNL 3G Hack for Unlimited Plan – Chennai

There are multiple techniques to hack the BSNL 3G service which you can find them in many mobile blogs, I have tried them but its not working in my area, however here is the 100% working technique to get 3G speed for mere 249.Rs instead of 1300.Rs. The trick is, to say in short, we activate GPRS service for 2G and change the tower to 3G network so we get 3G speed for browsing :)


Well, here are the steps to follow,
Step 1 : All you need is a 3G supported Mobile phone with 3G activated BSNL Sim in that.
Step 2 : Now top up your mobile with minimum 300 Rs.
Step 3 : Activate Unlimited GPRS plan by sending SMS in the following format,
GPRS249 to 53733
Step 4 : Now change your Network Operator from GSM to WCDMA/UTMS/3G depending on your handset,
Now enjoy unlimited Browsing in 3G speed :)

Note :

If you have doubt, You can check whether the system works or not in your circle by activating 7 rs. plan
by sending sms as “GPRS7″ to 53733 and do the same as above.

Available GPRS Packs :

Rs.7 – 50 MB 1 day
Rs.20 – Unlimited 1 day
Rs.13 – 200 MB 3 days
Rs.89 – 2 GB 1 mnth
Rs.249 – Unlimited for 1 months

This works 100% in Tamilnadu Circle ( Chennai ). I have around 5 of my friends using the trick in Chennai, do check it in your area and update us :)

Do you use this technique or any other trick ? do share with us below !

    i wish to know that it will work in maharashtra or not
    and the other thing is that in maharashtra unlimited plan is of Rs. 274.
    and i have 2g sim in which this plan is activated and after changing the network to utms it gives very good speed at starting for 10 days after that it again started givingspeed at 20-30kbps speed.
    so please give me the trick to again use the same sim at 3g speed.
    thank you.

    I live in West Bengal and I am using a 3G modem from Micromax, and BSNL 2G sim card to access 3G speed on BSNL network.
    To achieve this speed, activate the unlimited plan which comes @ Rs 198(in my case), and after doing that just maintain a min. balance of Rs50 in your account. Then just go to modem setting and select the UMTS.

    Now You are ready to get 3G speed at the cost of 2G tariff.

    This trick worked for me but the speed is upto 30kbps only,
    So Please give me the trick to increase the speed.

  4. rahul says

    I just confirmed with cc in chennai there’s unlimited plan with 3g @1499rs. and there’s unlimited plan in 2g@274. so bit confused what you are saying.
    moreover merely switching network won’t give the speed limit. but any way that’s good try. if you get a plan in 3g for 274/249 and saying it will go for unlimited then may be its not. if you are saying take plan in 2g and switch to 3g then your post need correction in point 1 as 2g sim.

  5. Abhinav says

    Guess how…….every1 makes a blog and publishes it online which is just a google search away………bsnl people are not that dumb……..

  6. Rahul Kapoor says


    Don’t do this trick, it is not working, Only one service will work at the same time, GPRS or 3G.
    When you activate GPRS by SMS it will just convert your 3G sim into 2G and after that you will receive GPRS Speed, No matter you select UMTS or GSM in the mobile you will receive the speed of GPRS. I am saying this because i faced this problem.
    If you thing the speed will be back after converting your 2G sim into 3G again then it won’t work bcoz the plan 248 is for 30 days and you cannot concert your sim to 3G until the voucher expires. in other words you will be stuck in 2G sim with GPRS speed for 30 days. I faced this problem and it gave me a very big headache.
    So use BSNL 3G with the correct way if you want faster speeds.

    Thank you

    @Anand Kumar : Yes,you are right. But, they didnt get 3g speed. One of my friend get 3g speed in new 3g sim without paying any bucks.

  8. RM says
