Is Airtel offering higher speed in its unlimited plan?

Today i was surfing net as usual when i was amazed to see my download speed. my plan is simple 512kbps unlimited plan and i normally get around 64kbps download speed but today i got 2mbps+ speed.  Check out the screenshot below

I couldnt believe it so i checked the speed on speedtest.net as well and i got the following result

I do not know how it happened but what i know is that i downloaded few movies in very less time because of this 😀

If anyone of you are facing the same then let me know :-). Thanks for spending time on my blog. keep visiting Techian for updates.
