3.Now go to the message option and write "backup" and send it to 6000 .Now this SMS will charge you 2 BDT and the offer charge is 23 BDT.So,you balance should have at least 30 taka so that you can avail the offer.

Now how to get unlimited internet through out the month by spending only 270 taka?
It is very easy and legal but a bit tricky.You need to have 10 SIM card of Grameen Phone.Now you need to activate the facility in all the SIM card.So,the calculation is :
(2+2+23) = 27 * 10 sim =270 taka and you will get 30 days facility of unlimited download and upload in all the SIM card.Please be noted that active the facility to another SIM when you first SIM card's facility will expire.
