Hi guys my name is jalal and taday I will share my experience about airtel . Last year I have a airtel sim . First time I recharged 399Rs for unlimited calling and per day 1.4 GB net. I thinked that it provides me all time free calling and high speed internet . But my thinking was wrong . When I call some one it didnot connect .when open the net it took most probably 2-3minutes for connecting . Its speed is 100kb/s-150kb/s. So, while I serched any website in google it was taking 4-5minutes for opened the website . For this, whenever I called the worker they told that we were working on it but month of month passed I saw nothing better on it . So guys I think donot buy the airtel sim.
