I was using the mobile operator vodafone from last too years. but I purchased an airtel number to use for internet usage and calling. but the cost of internet packs is very high and I am unable to purchase the internet packs because it is very costly.the speed of internet in our area is very bad. speed is not so good. when we open the browser some times its speed is good but sometimes the page is not opened and takes very long time to open.
Next problem is signal problem and the signal is not very good. I got inly one tower on my cell. and during the calling the call generally gets disconnected in between.
