I used to be a Bsnl customer for a long time.Recently along with Jio offers Bsnl also introduced the best offer that would blow your mind.
3GB data per day wow amazing isnt.
But its a trap people.The speed they are providing is unbearable.you have to wait like 5-6hrs to download a movie and you cant watch videos in YouTube without buffering.
Out of 3GB data you cant even reach 1 GB data.when we call customer care they will its a network problem they get in to it.
If you have real experience . dont buy bsnl
