I am using this network from last two years.
when coming to call charges and planes **Aircel** providing good topup offers when you recharge with 100 you will get more than 100. providing good reduced call charges.
From last three months they activated local calls 10ps/min offer.
Disadvantages
when you speak with some one you will get more voice disturbance some time network drops when you speak with some one.Finally I suggest you to don’t go with this network if you give very important to calls.
