Who doesn't like free internet? I have been surviving on free internet from telenor for months now without even recharching my balance. Yes i am that cheap, but i also don't use internet that much on mobile and places i go to usually have free wifi so i can get by easily.
Not many know that telenor has a mobile app called 'mytelenor' that can be used to activate custom packages, get loan, recharge balance etc. Basically all your sim management can be done using this app and more.
The best this is the daily free offers of internet that you can just activate without any additional charges. Just install the mytelenor app from appstore/playstore and you will start getting daily offers for internet and other packages.
There's also a 'Play and Win' feature where you answer a few general knowledge question and win free social MBs if you answer correctly. You can play this once daily so be sure to answer them correctly.
I have been using it daily to get free social mbs for whatsapp and facebook . Ocassionally i also get free general use internet offers.
