My first sim is Aircel and I still use it. I am using it because this is my orginal number. I network works fine but somtimes it gives so much of problem actually most of the times when I call someone or someone call me to the aircel number, the voice becomes shaky and very distrubing. So I stopped calling from my aircel number. So the network is poor. The data plans are also high every mobile operator is reducing their data plans now but aircel has no attracting new plans till now. The customer service is worst, they even could not tell why the calls keeps on droping suddenly.I think aircel should update their plans and reduce their price for data plans and most importantly improve their network.
